USB-to-serial converter breakout using the CH9102F chip, a near pin-compatible alternative to the CP2102N for UART-to-USB bridging.
Ground pin on the FTDI-like 6-pin edge header, visible on the Adafruit product image silkscreen.
Clear-to-send flow-control pin on the FTDI-like edge header; Adafruit notes CTS is the only flow-control pin not supported by the built-in Linux kernel driver.
Power wire on the FTDI-like edge header; Adafruit states the power wire is +5V.
Serial transmit output on the FTDI-like edge header, visible on the Adafruit product image silkscreen.
Serial receive input on the FTDI-like edge header, visible on the Adafruit product image silkscreen.
Request-to-send / auto-reset control pin; Adafruit states the 6th pin is RTS and the board matches its FTDI cables by default.
Modem-control pin available on the side header; Adafruit states the side header includes modem control pins such as DTR, RI and DSR.
Ring-indicator modem-control pin available on the side header per Adafruit product-page modem-control-pin description.
Data-set-ready modem-control pin available on the side header per Adafruit product-page modem-control-pin description.
