PinNinja

you won't need a multimeter ever again

Identify all UART pins by flashing a simple script.

Quickstart

  • Flash the script to an Uno.
  • Connect the UART Pins to A0,A1,A2,A3 in any order.
  • Switch on the device.
  • Connect the Arduino to your PC.
  • Open up the Serial Monitor.
  • See the magic happen.

Sample output

This has been tested on a couple of routers and on an ESP8266 with 100% success rate.

You can’t perform that action at this time.
