I am trying to connect my Adafruit PMS5003 PM2.5 Sensor to my Metro ESP32-S2 board.
The PM2.5 sensor needs to connect from the TX connector to a board with an RX connector along with the VCC and GND.
I have a Metro M4 AirLift Lite that has the RX connector and I can connect it to that board.
I can’t seem to locate an RX connector on the Metro ESP32-S2 board.
I have attached a screenshot of the Metro ESP32-S2 and I don’t see an RX connector.
Does the board have an RX connector?
Are you able to connect the PMS5003 PM2.5 Sensor to the Metro ESP32-S2 board?
Thanks,
Tom Henry

Re: Connect PMS5003 PM2.5 to the Metro ESP32-S2 Board
The ESP32 is kind of an odd duck: you’re right that there are no standard hardware Serial pins (there are a couple of pins that connect to the debugger’s UART, but that isn’t general-purpose IO.
Thing is, you can make a UART using any pins you want. This tutorial page shows how to do it:
