Arduino-based Adjustable Power Supply PCB (February 2022)

PCB for the Arduino-based Adjustable Power Supply project in the February 2022 issue of PE.

Please note this PCB is supplied without components.

We have published all sorts of fancy bench supplies over the years: linear, switchmode, hybrid, high-voltage, high-current, dual-tracking… But sometimes, all you need is a basic power supply with voltage and current monitoring and limiting; something that’s convenient and easy to set up and use. That’s exactly what this is – a very useful little power supply built on an Arduino shield!
