Bloom VS avrdude

Note also that, if you are on linux, there's the great https://bloom.oscillate.io/ project, which makes it really easy to debug AVR chips; I had great results and a wonderful experience with Bloom + VSCodium + Native debug plugin, or with CLion.

See the Bloom website for more: https://bloom.oscillate.io

You can read more on Bloom's TDFs here: https://github.com/navnavnav/Bloom/tree/master/src/Targets/TargetDescription

avrdude: Version 7.1-arduino.1 Copyright the AVRDUDE authors; see https://github.com/avrdudes/avrdude/blob/main/AUTHORS

The Windows version is to be found in the same place as the Linux/Unix versions: https://github.com/avrdudes/avrdude/

These programmers (picture1, picture2) are $5 plus shipping. Shipping within the US is $4. No extra shipping cost for multiple adapters. They can be used with ZFlasher AVR, avrdude 7, and pymcuprog. If you need assistance with flashing, there's a lot of good info at BLF, and I can help via PM. u/LiquidRetro also put together an excellent YouTube video.

you will also make sure you have the avrdude.exe installed to your computer in order to attach the firmware to the pro micro which you can find here https://github.com/avrdudes/avrdude

Yep, here it is, you need version 7.0.

Device signature is a unique 3-byte signature which helps to identify different Micro Controllers by their types as specified in the avrdude configuration file. Device signature of AVR Micro Controller can be very useful for many developers and engineers.These device signatures can be read from devices with the help of avrdude command line program.
