可以大量并联，提高输出能力。
拆件前的电路板上，就是两只并联，输出3.3v 6A厚度只有7.5mm用法简单，有电压输入和电压输出，外接可调电阻还可做成可调电源。
可以要自己改过可改成0.98V-20V可调恒流电源一、降压模式线路接法：Vin 与 GND 输入，Vout 与 GND 输出（脚的定义见上图）输出电压 = 0.925V * (R3 + R2) / R2；默认输出3.3V ~= 0.925V * (51K//51K + 10K) / 10K改变R3就可以调节输出电压第二种负压模式：实测输出19.5V1A线路接法：Vin 与 Vout 输入，Vin 与 GND 输出，Vadj 接Vin，去除R3 （脚的定义见图）例如： R1换成 200K，Vin 与 Vout 输入 5V，那么Vin 与GND 就输出 19.5V输出电压 = 0.925V * (R1 + R2) / R2； R1设为 200K，输出19.5V ~= 0.925V * (200K + 10K) / 10K改变R1就可以调节输出电压第三种负压模式 - 隔离电源（第一种负压模式变形）：使用高频磁环，也就是传说中的铁硅铝磁环 77120A7。

短路保护：恒流
输入反接保护：无，如有需要请加装二极管
接线方式：接线端子
产品尺寸（mm）：66(长)*50（宽）*21（高）
重量：43g
使用方法：
本模块有两种工作模式：简约模式和全功能模式，出厂默认是简约模式，如果需要使用全功能模式，可自行开启。
简约模式使用方法：
1、正确连接输入、输出，保证输入电压在要求的范围内，严禁反接。
2、设定所需的电压电流值，设定电压电流值的方法如下：
上电后默认显示的是电压设定值，电压值显示的格式是“00.00”，按下“SET”按键可以切换到电流设定值，电流值显示的格式是“0.000”，按下按键增大设定值，按下按键减小设定值，短按精确设定，长按可以快速设定。
电压或者电流值发生变化后，按下“SET”键后会显示“----”，表示保存了当前设定的电压或者电流值。
若没有改变电压或者电流值，按“SET”键会切换到电流或者电压值。
3、设定完成后按下“OK”按键就可以输出了。
4、输出状态下，在显示电压值时按下按键可以增大输出电压，按下按键可以减小输出电压，在显示电流值时按下按键可以增大电流设定值，按下按键可以减小电流设定值，短按精确设定，长按可以快速设定。
输出状态下短按“OK”按键可以切换显示电压、电流、功率、容量等参数，长按3秒可以自动轮显，再次长按可以取消轮显。
在轮显状态下，按按键无效。
5、输出状态下，按下“SET”按键可以关闭输出。
全功能模式使用方法：
本模块有三项特殊功能，默认都处于关闭状态，如有需要，可自行开启。
功能0：上电后自动输出
功能1：保存与调出设定的参数，显示功率和容量
功能2：输出后自动轮显参数
开启/关闭方法：
长按“OK”按键，然后给模块通电，数码管会在“--0-”~“--2-”之间循环显示，在显示“--0-”时松开“OK”按键会开启或者关闭功能0，在显示“--1-”时松开“OK”按键会开启或者关闭功能1，在显示“--2-”时松开“OK”按键会开启或者关闭功能2。
若松开“OK”按键后数码管显示“--y-”表示已开启当前的功能，显示“--n-”表示已关闭当前的功能。
1、启用功能0后上电之后会自动输出。
2、启用功能1之后，在未输出状态下，按下“SET”按键可以在电压“00.00”，电流“0.000”，调出参数“Lo.-0”和保存参数“SA.-0”之间循环切换。
下面举例说明该功能：
例如需要把10V，1.5A保存在存储位置1并且调出存储位置1的参数。
1按下“SET”按键切换到电压值，设定电压值为10.00V，按下“SET”按键保存当前设定的电压值。
2按下“SET”按键切换到电流值，设定电流值调为1.500A，按下“SET”按键保存当前的电流值。
3按下“SET”按键切换到“SA.-0”，按按键选择存储位置，这里需要调整到“SA.-1”，按下“OK”按键就可以把设定的“10V，1.5A”保存在存储位置1。
4按“SET”按键调整到“Lo.-0”，按按键选择需要调出的存储位置的参数，这里需要调整到“Lo.-1”，按下“OK”按键就可以调出存储位置1的参数。
5本机共有0~9共10组存储位置，每组存储位置都可以任意设定电压电流值，各个存储位置互相独立，互不影响。
3、启用功能2后在输出时会自动轮显电压、电流、功率、容量等参数。
注意事项：
1、正确连接输入输出，严禁反接，反接会烧坏模块。
2、本模块是降压模块，输入要高于输出1.5V以上。
3、输出2A以下自然散热即可，输出2A以上须加强散热。
显示说明：
00.00：电压值，单位V，00.00~36.00V
0.000：电流值，单位A,0.000~3.000A
P.000、P0.00、P00.0、P000.：功率值，单位W，小数点的位置随着功率的变化而改变位置。
例如：P.123表示0.123W,P1.23表示1.23W，P12.3表示12.3W, P102.表示102W
C.000、C0.00、C00.0、C000.：容量值，单位AH，小数点的位置随着容量的变化而改变位置。
例如：C.123表示0.123AH，C1.23表示1.23AH，C12.3表示12.3AH、C123.表示123AH
