OK, got a replacement FTDI stick today and that works OK so now working through testBuzzer and onwards :-)
A couple of queries though -
1. the Arduino IDE reports ATmega328P (5V, 20MHz) Nyboard V0_1 using the URL in the Nybble documentation for the relevant board JSON. I'm on Nybble board 0.2 so is there an updated to the Arduino IDE needed or is this version compatible?
2. What's the latest set of documentation that I should be using to progress with the next stages of calibration, attaching legs/head/tail etc. (I'm using Assembling Instructions for Nybble.pdf that you wrote dated June 29, 2019 - is that the best & latest reference?)
Thanks.
