A pro micro is quite expensive, especially during the current chip shortage. Buying hot-swap-sockets and using the same microcontroller for many boards is the way to go. This socket lets you use your pro micro (and other similar microcontrollers) without having to permanently stick it to your PCB.
Included: 1x pro micro socket
please note, the regular pin headers included with the pro micro are too thick and will NOT work with this socket. I recommend using official mill max socket pins or cut-off diode legs.
