As usual I’ll be using a NodeMCU board (I really did order a lot of them) which uses an ESP8266 ... work! What’s your best and worst idea for microcontrollers that interact with the blockchain?

When I began programming microcontrollers ... ESP8266 for the majority of my projects, the ESP32 has more than earned itself a place on my workbench now that I know how to compile custom NodeMCU ...
