This was handy for a few reasons. Very clear visuals of all the key information that makes it much appreciated. I was using a $12 board with a CP210 comms chip doing USB->Serial/TTL conversion and there was a little confusion over the location of the A/B pins for RS-485. Once I solved that issue, the guide you have here was great, and this board is so small I can wire it up to a female USB-C socket and just use a normal USB cable for the PC connection.
