Connect the SEN5x board to your ESP8266/NodeMCU board as follows. SEN5x GND → ESP8266/NodeMCU GND SEN5x 5V → 5V input (note that the "5V" pin of NodeMCU or D1 mini dev boards is connected to its USB ...

NodeMCU ESP8266 to Adafruit Motor Shield V1. This is an old motor driver. I couldn't find any esp8266 connection with this motor driver anywhere. I made a connection in this way. I hope I could help.

As usual I’ll be using a NodeMCU board (I really did order a lot of them) which uses an ESP8266, but there’s no reason this would be difficult to achieve on an Arduino-based device.
