Custom MCU-Controlled Bench Power Supply with Free-Running, Constant-Voltage, and Constant-Current Modes. Configurable Automatic Over-Voltage, Under-Voltage, Over-Current, and Under-Current Cutoff! [Custom Bench Power Supply](https://preview.redd.it/k3tnynvin7yg1.png?width=3992&format=png&auto=webp&s=83789e386f5cccfcadabd10b3b640294fafa1ab0) I'm working on a balancing bot project that needs multiple voltages and I've never had a decent bench power supply. So in the middle of the other project I decided to build a 3-channel bench supply with 3 modes: Free-Running, Constant-Voltage and Constant-Current. 12V, 2A, on three independent output channels. It has automatic output cutoff for 4 independent limits that can be optionally enabled on the fly to help protect things or limit the damage if/when I do something stupid 😉 The full working version with the first channel is totally working!…
