Adafruit CP2105 Friend - USB to Dual UART Serial Converters

Perfect for seamless connectivity, the Adafruit CP2105 Friend lets you transfer serial data from two ports to USB with ease. It features dual UART ports—one 'standard' and one 'enhanced'—each uniquely optimized for data integrity and speed.

Enhanced port specifications: supports data bits (5-8), stop bits (1, 1.5, 2), parity options (odd, even, mark, space, no parity), and baud rates from 300 bps to 2.0 Mbps. It includes 320-byte receive and transmit buffers along with modem control signals like CTS, RTS, DTR, DSR, and RI.

Standard port specifications: handles 8 data bits, 1 stop bit, various parity options, and baud rates between 2400 bps and 921600 bps. Features 288-byte receive and transmit buffers and similar modem control signals as the enhanced port.

Built with flexibility in mind, this board uses a USB-C connector and has separate interfaces for each port—Enhanced on the left, Standard on the right. The board comes with no extra GPIO pads or LEDs, ensuring a minimalist design with clear access to necessary inputs and outputs.

Designed for stability, it provides superior driver support and high-speed capabilities compared to other options. Each unit is fully assembled and tested, with pin headers included for easy integration into your projects. Compatible with Linux, Windows (auto driver download), and Mac OS X (via SiLabs driver page).
