After successfully downloading a sketch to my Pro Micro C about 100 times, it no longer is even recognized by my Windows-10 laptop when I plug it in.
I connected another Pro Micro C, downloaded the sketch, and it works fine.
Is my original Pro Micro C due for proper burial?
Hello Bob.
Hard to say, it could be a small glitch that bricked the board, but fortunately these are pretty easy to recover. Check the “How to recover a bricked Pro Micro” section in our [hookup guide and see if that gets you back up and running. If it doesn’t, PM me with your order number. :-)](Qwiic Pro Micro USB-C (ATmega32U4) Hookup Guide - SparkFun Learn)
Yup the “bricked pro micro” advice did the trick.
