DRV8825步进电机驱动器载板说明书
DRV8825 Stepper Motor Driver Carrier, High CurrentDRV8824/DRV8825 stepper motor drivercarrier with dimensions.OverviewThis product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the driver’s key features:Simple step and direction control interfaceSix different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and1/32-stepAdjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step ratesIntelligent chopping control that automatically selects the correct current decaymode (fast decay or slow decay)45 V maximum supply voltageBuilt-in regulator (no external logic voltage supply needed)Can interface directly with 3.3 V and 5 V systemsOver-temperature thermal shutdown, over-current shutdown, and under-voltage lockoutShort-to-ground and shorted-load protection4-layer, 2 oz copper PCB for improved heat dissipationExposed solderable ground pad below the driver IC on the bottom of the PCBModule size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)We also carry a DRV8824 stepper motor driver carrier that can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors. The DRV8824 can only deliver up to 0.75 A per coil without a heat sink (1.2 A max with proper cooling), but it has larger current-sense resistors that allow for better microstepping performance than the DRV8825 carrier at low currents. The only way to tell our DRV8824 carrier apart from the DRV8825 carrier is by the markings on thedriver IC; if you have a mix of the two, you might consider marking them (there is a blank square on the bottom silkscreen you can use for this). For lower-voltage applications, consider our pin-compatible DRV8834 carrier, which works with motor supply voltages as low as 2.5 V.This product ships with all surface-mount components—including the DRV8825 driver IC—installed as shown in the product picture.Some unipolar stepper motors (e.g. those with six or eight leads) can be controlled bythis driver as bipolar stepper motors. For more information, please see the frequentlyasked questions. Unipolar motors with five leads cannot be used with this driver.Included hardwareThe DRV8825 stepper motor driver carrier ships with one 1×16-pin breakaway 0.1" male header. The headers can be soldered in for use with solderless breadboards or 0.1" female connectors. You can also solder your motor leads and other connections directly to the board.Caution: Installing the header pins so that the silkscreen side is up and the componentsare down can limit the range of motion of the trimpot used to set the current limit. If youplan on installing the header pins in this orientation, please set the current limit beforesoldering in the pins.Using the driverMinimal wiring diagram for connecting a microcontroller to a DRV8824/DRV8825 stepper motor drivercarrier (full-step mode).Power connectionsThe driver requires a motor supply voltage of 8.2 – 45 V to be connected across VMOT and GND. This supply should have appropriate decoupling capacitors close to the board, and it should be capable of delivering the expected stepper motor current.Warning: This carrier board uses low-ESR ceramic capacitors, which makes itsusceptible to destructive LC voltage spikes, especially when using power leads longerthan a few inches. Under the right conditions, these spikes can exceed the 45 Vmaximum voltage rating for the DRV8825 and permanently damage the board, evenwhen the motor supply voltage is as low as 12 V. One way to protect the driver from such spikes is to put a large (at least 47 µF) electrolytic capacitor across motor power (VMOT) and ground somewhere close to the board.Motor connectionsFour, six, and eight-wire stepper motors can be driven by the DRV8825 if they are properly connected; a FAQ answer explains the proper wirings in detail.Warning: Connecting or disconnecting a stepper motor while the driver is powered candestroy the driver. (More generally, rewiring anything while it is powered is asking fortrouble.)Step (and microstep) sizeStepper motors typically have a step size specification (e.g. 1.8° or 200 steps per revolution), which applies to full steps. A microstepping driver such as the DRV8825 allows higher resolutions by allowing intermediate step locations, which are achieved by energizing the coils with intermediate current levels. For instance, driving a motor in quarter-step mode will give the 200-step-per-revolution motor 800 microsteps per revolution by using four different current levels.The resolution (step size) selector inputs (MODE0, MODE1, and MODE2) enable selection from the six step resolutions according to the table below. All three selector inputs have internal 100kΩpull-down resistors, so leaving these three microstep selection pins disconnected results in full-step mode. For the microstep modes to function correctly, the current limit must be set low enough (see below) so that current limiting gets engaged. Otherwise, the intermediate current levels will not be correctly maintained, and the motor will skip microsteps.MODE0MODE1MODE2Microstep ResolutionLow Low Low Full stepHigh Low Low Half stepLow High Low1/4 stepHigh High Low1/8 stepLow Low High1/16 stepHigh Low High1/32 stepLow High High1/32 stepHigh High High1/32 stepControl inputsEach pulse to the STEP input corresponds to one microstep of the stepper motor in the direction selected by the DIR pin. These inputs are both pulled low by default through internal 100kΩ pull-down resistors. If you just want rotation in a single direction, you can leave DIR disconnected.The chip has three different inputs for controlling its power states: R ESET, SLEEP, and ENBL. For details about these power states, see the datasheet. Please note that the driver pulls the SLEEP pin low through an internal 1MΩ pull-down resistor, and it pulls the RESET and ENBL pins low through internal 100kΩ pull-down resistors. These default RESET and SLEEP states are ones that prevent the driver from operating; both of these pins must be high to enable the driver (they can be connected directly to a logic “high” voltage between 2.2 and 5.25 V, or they can be dynamically controlled via connections to digital outputs of an MCU). The default state of the ENBL pin is to enable the driver, so this pin can be left disconnected.Schematic of nSLEEP and nFAULT pins onDRV8824/DRV8825/DRV8834 carriers.The DRV8825 also features a FAULT output that drives low whenever the H-bridge FETs are disabled as the result of over-current protection or thermal shutdown. The carrier board connects this pin to the SLEEP pin through a 10k resistor that acts as a F AULT pull-up whenever SLEEP is externally held high, so no external pull-up is necessary on the FAULT pin. Note that the carrier includes a 1.5k protection resistor in series with the FAULT pin that makes it is safe to connect this pin directly to a logic voltage supply, as might happen if you use this board in a system designed for the pin-compatible A4988 carrier. In such a system, the 10k resistor between SLEEP and FAULT would then act as a pull-up for SLEEP, making the DRV8825 carrier more of a direct replacement for the A4988 in such systems (the A4988 has an internal pull-up on its SLEEP pin). To keep faults from pulling down the SLEEP pin, any external pull-up resistor you add to the S LEEP pin input should not exceed 4.7k.Current limitingTo achieve high step rates, the motor supply is typically much higher than would be permissible without active current limiting. For instance, a typical stepper motor might have a maximum current rating of 1 A with a 5Ω coil resistance, which would indicate a maximum motor supply of 5 V. Using such a motor with 12 V would allow higher step rates, but the current must actively be limited to under 1 A to prevent damage to the motor.The DRV8825 supports such active current limiting, and the trimmer potentiometer on the board can be used to set the current limit. You will typically want to set the driver’s current limit to be at or below the current rating of your stepper motor. One way to set the current limit is to put the driver into full-step mode and to measure the current running through a single motor coil without clocking the STEP input. The measured current will be 0.7 times the current limit (since both coils are always on and limited to approximately 70% of the current limit setting in full-step mode). Another way to set the current limit is to measure the voltage on the “ref” pin and to calculate the resulting current limit (the current sense resistors are 0.100Ω). The ref pin voltage is accessible on a via that is circled on the bottom silkscreen of the circuit board. The current limit relates to the reference voltage as follows:Current Limit = VREF × 2So, for example, if you have a stepper motor rated for 1 A, you can set the current limit to 1 A by setting the reference voltage to 0.5 V.Note: The coil current can be very different from the power supply current, so youshould not use the current measured at the power supply to set the current limit. Theappropriate place to put your current meter is in series with one of your stepper motorcoils.Power dissipation considerationsThe DRV8825 driver IC has a maximum current rating of 2.5 A per coil, but the current sense resistors further limit the maximum current to 2.2 A, and the actual current you can deliver depends on how well you can keep the IC cool. The carrier’s printed circuit board is designed to draw heat out of the IC, but to supply more than approximately 1.5 A per coil, a heat sink or other cooling method is required.This product can get hot enough to burn you long before the chip overheats. Take carewhen handling this product and other components connected to it.Please note that measuring the current draw at the power supply will generally not provide an accurate measure of the coil current. Since the input voltage to the driver can be significantly higher than the coil voltage, the measured current on the power supply can be quite a bit lower than the coil current (the driver and coil basically act like a switching step-down power supply). Also, if the supply voltage is very high compared to what the motor needs to achieve the set current, the duty cycle will be very low, which also leads to significant differences between average and RMS currents. Additionally, please note that the coil current is a function of the set current limit, but it does not necessarily equal the current limit setting. The actual current through each coil changes with each microstep. See the DRV8825 datasheet for more information.Schematic diagramSchematic diagram for the DRV8824/DRV8825 stepper motor driver carrier.The current sense resistors (R2 and R3) on the DRV8825 carrier are 0.100 Ω. This schematic is also available as a downloadable pdf (196k pdf).Key differences between the DRV8825 and A4988The DRV8825 carrier was designed to be as similar to our A4988 stepper motor driver carriers as possible, and it can be used as a drop in replacement for the A4988 carrier in many applications because it shares the same size, pinout, and general control interface. There are a few differences between the two modules that should be noted, however:DRV8825 stepper motor drivercarrier.A4988 stepper motor drivercarrier, Black EditionThe pin used to supply logic voltage to the A4988 is used as the DRV8825’s FAULT output, since the DRV8825 does not require a logic supply (and the A4988 does not have a fault output). Note that it is safe to connect the FAULT pin directly to a logic supply (there is a 1.5k resistor between the IC output and the pin to protect it), so the DRV8825 module can be used in systems designed for the A4988 that route logic power to this pin.The SLEEP pin on the DRV8825 is not pulled up by default like it is on the A4988, but the carrier board does connect it to the FAULT pin through a 10k resistor. Therefore, systems intended for the A4988 that route logic power to the FAULT pin will effectively have a 10k pull-up on the SLEEP pin. (This 10k resistor is not present on the initial(md20a) version of the DRV8825 carrier.)The current limit potentiometer is in a different location.The relationship between the current limit setting and the reference pin voltage is different.The DRV8825 offers 1/32-step microstepping; the A4988 only goes down to 1/16-step.The mode selection pin inputs corresponding to 1/16-step on the A4988 result in 1/32-step microstepping on the DRV8825. For all other microstepping resolutions, the step selection table is the same for both the DRV8825 and the A4988.The timing requirements for minimum pulse durations on the STEP pin are different for the two drivers. With the DRV8825, the high and low STEP pulses must each be at least 1.9 us; they can be as short as 1 us when using the A4988.The DRV8825 has a higher maximum supply voltage than the A4988 (45 V vs 35 V), which means the DRV8825 can be used more safely at higher voltages and is less susceptible to damage from LC voltage spikes.The DRV8825 can deliver more current than the A4988 without any additional cooling (based on our full-step tests: 1.5 A per coil for the DRV8825 vs 1.2 A per coil for theA4988 Black Edition and 1 A per coil for the original A4988 carrier).The DRV8825 uses a different naming convention for the stepper motor outputs, but they are functionally the same as the corresponding pins on the A4988 carrier, so the same connections to both drivers result in the same stepper motor behavior. On both boards, the first part of the label identifies the coil (so you have coils “A” and “B” on the DRV8825 and coils “1” and “2” on the A4988).For those with color-sensitive applications, note that the DRV8825 carrier is purple. In summary, the DRV8825 carrier is similar enough to our A4988 carriers that the minimum connection diagram for the A4988 is a valid alternate way to connect the DRV8825 to a microcontroller as well:Alternative minimal wiring diagram for connecting a microcontroller to a DRV8824/DRV8825 steppermotor driver carrier (full-step mode).Documentation on producer website.。

板子使用全新的L297作为控制芯片 L298作为驱动芯片板载NE555时钟电路为L297提供CLK因此该版在不需要外部控制的情况下就可以工作板载3个控制按键EN - 使能
CW - 反向旋转
HF - 半速旋转
通过按键就可以直接控制电机的正反转、全速/半速和使能。
三、基本功能描述:
通过光藕隔离之后将CLK CW HF EN四个基本控制端引出单片机等可以非常方便的控制电路的工作这个板子改进的地方比较多也方便研究使用。
板子使用1N5822快速二极管作为续流器件其速度要远远快于整流桥的 L298和电机能够提供更完善的有效的保护。
模块供电+ 5V(L297和L298控制供电) +12V(根据电机最低4V最高16V)给电机供电。
电机输出接口包括: +12V 四相输出 GND(请根据您的电机连接)。
控制输入接口包括: GND CLK EN CW HF。
需要特别说明的是:为了测试方便在板子上设置了NE555构成的一个低频时钟源（使用时跳线冒打在CLK-555处），当您使用外部的时钟信号控制电机的转速时必须跳线冒打在CLK -CPU处否则外部时钟是不会传到L297里面。
四、接口说明:
1、板子左上方小二接口(JT1) VCC接+5V、GND接电源地，次处为芯片L297和555芯片的工作电压；
2、板子左中方小八接口(MCU-IN)为光藕隔离的信号分别为：EN(使能)、RET(复位)、C/CW(正反控制)、H/FU(全速/半速)、CLK(时钟信号) +5V（光藕工作电压）注意：如果没有用C PU控制，小八接口(MCU-IN)的信号可以不接任何东西。
3、JT2为298的工作电压也是驱动电机的工作电压(接+12V)
注意：板子推荐的最高电机供电电压在4V~18V之间最大工作电流不超过2A 否则L298的耗散功率会过大导致发热严重这种情况下通过风冷等措施可以提高最大工作电流到2. 5A左右。
