Adafruit PiUART - USB Console and Power Add-on for Raspberry Pi
Here's another super handy add-on for your Raspberry Pi computer, perfect for 'head-less' setups! The PiUART adds a USB Type-C to serial connection so you can use any serial port software to connect to the Pi's console.
Pinout
- 5V
Raspberry Pi 5V power rail. Adafruit Learn states the 5V power pins can be fed from the board USB connector when the switch is ON; product page identifies this revision as USB Type-C.
