USB Type-C to serial add-on for headless Raspberry Pi setup, with TX/RX LEDs for data activity indication.

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.
Ground connection on the Raspberry Pi header side of the PiUART add-on.
Raspberry Pi UART transmit console signal used by the PiUART USB-to-serial connection.
Raspberry Pi UART receive console signal used by the PiUART USB-to-serial connection.
USB-to-serial console and optional power input for the Raspberry Pi, described on the Adafruit product page as a USB Type-C to serial connection with switchable Pi power.
On-off switch controlling whether the PiUART feeds the Raspberry Pi 5V rail from USB power.
