{"title":"Adafruit CP2102N Friend - USB to Serial Converter","handle":"adafruit-cp2102n-friend-usb-to-serial-converter","url":"/products/adafruit-cp2102n-friend-usb-to-serial-converter","description":"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.\n\nThe 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.\n\nKey Features\n\n\nCP2102N Chip – Up to 3 Mbps transfer speed with reprogrammable settings memory\n\nUSB Type-C – Modern connector for reliable, reversible connection\n\nFTDI-Compatible Pinout – Drop-in replacement for FTDI cables and CP2104-based boards\n\nAuto-Reset – Works with Arduino/ATmega328 for one-click uploads\n\n3.3V Signal Levels – 5V-compliant, works with both 3.3V and 5V systems\n\nRX/TX LEDs – Visual data transfer indicators\n\nFull Modem Control Pins – DTR, RTS, RI, DSR, and more on side pads\n\n\nDriver Support\n\n\nLinux – No driver required (built into kernel)\n\nWindows – Automatic driver installation via Windows Update\n\nmacOS – Driver available from Silicon Labs\n\n\n\nIdeal For\n\nUploading firmware to Arduino, ESP8266, ESP32, and other FTDI-port microcontrollers\nSerial debugging and data monitoring\nReplacing older FTDI or CP2104-based serial adapters\n\n\nPackage Contents\n\n1× Adafruit CP2102N Friend breakout (assembled and tested)\n1× Right-angle socket header\n1× Male header strip\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2487,"title":"Default Title","sku":"AF-5335","price":11.12,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
