This DC-DC step-down (buck) module accepts up to 40V input and outputs from 1.2V to to input voltage. It has very strong output ability and could output up to 3A current.
The output voltage could be adjusted by tuning the blue potentiometer.
- input voltage: up to 40V
- output voltage: 1.2V~Vin (adjustable)
- output current: up to 3A
- with adjustable potentiometer to adjust the output voltage
