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. What now? Enter the Adafruit CH9102F Friend, a version of our popular USB-Serial 'friend' breakouts that uses the affordable (and available) CH9102F - a 'near pin-compatible' to the CP2102N. This board features the CH9102F USB-Serial chip that can upload code at 3Mbit/s for fast development time. It also has auto-reset for Arduino/ATmega328 boards so no noodling with pins and reset button pressings. The CH9102F has fairly good driver support, and for 99% of use cases is a fine replacement of the FTR232, FT231x or CP210x series. With a modern USB Type C connector, it's ready to rock on any kind of computer

Setup Guide

Identify the pins

Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.

Wire to your microcontroller

Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.

Install libraries

In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.

Upload example sketch

Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.

Calibrate if needed

Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
