Doing this obviously means we will need to change the core hardware design to handle the change from the Arduino Nano and the Expansion Shield ... to a NodeMCU ESP8266 Or ESP32 ... the only expansion board I have been able to identify as a possible solution is the L293D Motor Driven Expansion Board for NodeMcu I do not have one of these boards yet ... and don't know how it interfaces to the esp yet either and we don't need the L293D ... It may be worth creating a custom break-out board for the project ... based on the NodeMCU ESP8266 & ESP32 ❓
