Adafruit CP2102N Friend - USB to Serial Converter
We have ✅ 1 available of the AF-5335 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Adafruit CP2102N Friend is a USB-to-serial converter breakout featuring the Silicon Labs CP2102N chip with USB Type-C. It provides reliable serial communication at up to 3 Mbps, making it ideal for uploading firmware to Arduino, ESP8266, ESP32, and other microcontrollers that use an FTDI-style serial header.
The board is configured to match the standard FTDI cable pinout, with 5V power on the power pin and 3.3V signal levels (5V-compliant). It includes auto-reset circuitry for Arduino/ATmega328 boards, so you can upload code without manually pressing the reset button. RX/TX LEDs blink during data transfer for easy debugging.
