#36 Connecting to GMC-300 Geiger Counter using a serial port (not through USB).

There are already instructions how to connect to GMC300-type geiger counter using USB, but I couldn't find any instructions on using the actual serial port that's directly on the board. In this video I'll show you how to do that. This should work on GQ GMC-300, GMC-320, GMC-300E and other variations. code: https://gist.github.com/ungineer/aa027fde824e19be8453391b7b55f620 Soldering Iron: pine64 direct - https://pine64.com/product/pinecil-sm...
