If anyone has thoughts about the future of OpenHAK hardware, this is the spot for it. Biggest update would be to the radio module. There are lots of options these days. Right now I'm looking at nRF52840. Adafruit has a module
https://www.adafruit.com/product/4062That I have on my desk. There's enough other parts floating around the lab to lash up a prototype. Anyone in NYC interested in playing, plz reply to this thread.
Happy 2020!
