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


Features:

  1. Board features the CH9102F USB-Serial chip that can upload code at  3Mbit/s for fast development time
  2. It also has auto-reset for Arduino/ATmega328 boards so no noodling with pins and reset button pressings.
  3. Works excellently with any Arduino, ESP8266, ESP32, or any other microcontroller that uses an ‘FTDI port’ for communications and upload

Package Includes:

1 x Adafruit WCH CH9102F Friend – USB to Serial Converter

Converter for connecting the Lidar TFmini / TF02 / TF03 distance sensor with a TTL/CAN communication interface to a PC with a USB port in order to check the parameters/data via the Benewake Windows Display Program with graphic interface. A USB miniUSB cable is also included.

Note: For more technical details go through Datasheet in the attachment sections


Features:

  1. Blind Zone: 10cm
  2. Distance resolution: 1cm
  3. Accuracy: ±10cm (within10m) ,1% (beyond 10m)

Package Includes:

1 x TTL / CAN to USB converter for TF LiDAR
