I tried this solution on my sparkfun pro micro 3.3v, but upon substituting the promicro8 hex file for the promicro16 hex file, I get the following error when trying to burn the (faked out) 5V bootloader:
avrdude: verification error, first mismatch at byte 0x001c
0xff != 0xfe
avrdude: verification error; content mismatch
Maddeningly, the errors aren’t even consistent. Other times that I try (after changing nothing), I get different byte numbers called out as the mismatch location. However, it is always complaining that 0xff != 0xfe.
These errors appear after quite a long while – about the same length of time I was previously used to waiting for a successful bootloader burn on a 5V pro micro.
Any ideas? Thanks in advance!

Any ideas on whether this receiver could be suitable to receive 315 MHz signals from tire pressure monitoring system transmitters?
I’m a little concerned it’ll be super hard to get good data from this receiver because of everyone’s comments about noise ….
Has anyone run into problems using the EEPROMex library on these Pro Micro boards? I used that library flawlessly on an Arduino Uno, but I think using it bricked by Pro Micro 5V (I was able to recover it by reflashing the bootloader: https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader/uploading-code—easy-way), but I’m wary of trying again.
Any ideas on how to easily use EEPROM memory would be fantastic! Thanks!
