Pro Micro with Atmega32U4 chip Development Board, AYWHP 1 PCS Pro Micro 5V/16MHz Nano microcontroller Development Board with Built-in USB updater Type-C Interface Compatible with Arduino IDE

Arrived quickly and worked great with my custom keyboard build that I'm typing this review on. The 3 pack is a great value so I'll be keeping a couple of these around for sure.

These are very nice quality and 3 of 3 worked fine. These have the USB-C connector. Just what I needed.

On 3/3 of these boards I got, each USB c port had an issue. Using a known good cable, each cable becomes "stuck" in these boards, leading to the pins inside the USB c port breaking (at the far right). The PCB itself seems to be decent quality. Hard to say if I just happened to get 3 boards of a bad run or what.

I ordered these for the value and availability. Got my project done on time. I did manage to brick two boards, but it was my fault for rushing and shorting them out.

Good little mcu but do note that this does have less available pins than the genuine Arduino micro. The actual processor has some decent specs as far as micro controllers go, but there are some more modern options that do give a bit more performance with more GPIO like the RP2040. It has a usb interface built in so it can be used for HID projects or the like. It is pretty easy to use, you can just use platform up or Arduino ide. Its value is not bad but you can find a lot of micro controllers with similar or better specs for the same price and it is moderately quick definetly not the fastest.

Used this with our satellite tracker for Ham Radio, works great

Priced well. Work as intended.

These will not power up when connected to the usb cable and by default are not recognized by the IDE. Completely useless. Bad batch maybe? In case you are wondering I checked my computer, IDE and cables with working USB-3 Pro Micros from another vendor and these were fine.
