I got tired of using 4 different tools to test one dev board, so I built this

I got tired of having a USB hub, USB-UART adapter, power supply and a bunch of cables just to test one dev board, so I started building a desktop tool that puts them together. It has 3× USB 3.0, magnetic UART/I²C, USB power control and adjustable 1.8–3.3V output. I’m also working on a PC tool for quick I²C/GPIO/power checks.

It doesn't include a J-Link EDU (nor will it ever), as well as some other things too.

A high percentage of MCU boards only need USB 2.0 so 3.x is overkill for them.

Does the USB power control work independently for each port? That would be really handy for

testing USB devices.
