USB Power Breakout PCB

Post by parkview » Sat May 13, 2023 4:59 pm

The other day I wanted to do a quick breadboard circuit test and I needed to get 5V and 3.3V onto the circuit. I have a nice RPi based Hat that could be used to inject power to the breadboard, but it's a monster and I thought all I need is a simple small PCB. So I spent a few hours to make my own one up:

These should supply 2A 5V, with 700mA 3.3V via a USB-C connector. There is a red LED across the polyfuse, with the idea that it should light up when the fuse activates - kind of giving a warning. It's two side and small, so it would be easy and cheap to make into a panel for cheaper production cost. Another thought would be to add a USB Micro connector onto it as well - just to give connection options. Although it would make it sizably larger.

JLCPCB where kind and sent me six of these small PCB's. It didn't take long to assemble two of them and they all work fine. I think if I did another version, I would place the GND pin in the middle, so the pin out would be: 5V - GND - 3.3V That way I could just solder two pins if I only needed one set of voltages and it would then plug into a breadboard power rail.

I think the board came out well though:
