Adafruit WCH CH9102F Friend - USB to Serial Converter
Long gone are the days of parallel ports and serial ports. Now the USB port reigns supreme! But USB is hard, and you just want to transfer your everyday serial data from a microcontroller to computer.
Pinout
- GND1
Ground pin on the FTDI-like 6-pin edge header, visible on the Adafruit product image silkscreen.
Type · groundVoltage · 0V - CTS2
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.
Type · controlVoltage · 3.3V signal level, 5V compliant per Adafruit product page - 5V3
Power wire on the FTDI-like edge header; Adafruit states the power wire is +5V.
Type · powerVoltage · +5V - TXO4
Serial transmit output on the FTDI-like edge header, visible on the Adafruit product image silkscreen.
Type · signalVoltage · 3.3V signal level, 5V compliant per Adafruit product page
Start wiring
UART · 0V · 3.3V signal level, 5V compliant per Adafruit product page
Verify supply voltage and logic levels before powering up.
Module pins: 5V, GND, TXO, RXI. Schematik maps them to your board in the app.
