About the Dual Power Supply PCB

Dual Power Supply is an open source PCB design by HighCarlSagan, published on GitHub under the Custom license license. It is a 4-layer board measuring 150 × 80 mm, with 57 components from 17 distinct parts.

By type, the board carries 26 resistors, 24 capacitors and 4 connectors.

It belongs with the power & battery, sensors and dev boards & breakouts designs in this gallery.

From the project

Universal power supply with 5V and 3v3 output, upto 60 Watts total. 6A on each rail.

A compact mains-input dual-output bench supply built around an isolated AC-DC brick and two integrated buck modules. Provides clean, regulated 5 V and 3.3 V rails for hobby electronics — bench bringup, MCU dev boards, sensors, LEDs, and small actuator loads.

I wanted a single, always-on bench supply that I could leave plugged in and tap into for anything I'm prototyping: ESP32s, Pis, sensor breakouts, the Telegram-controlled lights board, whatever.
