Hi.

The entire circuit is powered by a USB cable from the computer. I am using the ESP32 DevKit V4 module. E32 is powered from pin 5V. Mo and M1 are connected to 0V. AUX, TXD and RXD are connected via 4k7 resistors to pin 3V3 on the ESP32 module. RXD and TXD are connected to the TX2 and RX2 pins of the ESP32 module. The GND pin of the E32 module is connected to the GND pin of the ESP32 module and the GND of the USB cable.
According to the pictures in your article it should be fine.

What connection error did you have?

Hi Peter.
