Product description
Adafruit MCP2221A Breakout is a compact interface board that makes it possible to connect a computer (Windows/Mac/Linux) directly to digital devices, sensors, and other modules via USB without the need for an external microcontroller. The board is based on Microchip’s MCP2221A, which provides USB-to-serial conversion with support for digital input/output (GPIO), analog-to-digital conversion (ADC), and I2C communication. The digital GPIO pins can be used to drive LEDs, read buttons, or other digital signals, and the ADC functions enable measurement of analog voltage levels. The I2C interface is suitable for communication with common sensors and OLED displays. The board is powered from the computer via a USB-C connection and includes a Qwiic connector for simple and fast plug-and-play connection to compatible sensors and modules. Extensive Python libraries and tutorials make it easy to integrate the board into prototypes and test setups on Mac, Windows, and Linux, with support for CircuitPython. There is no internal firmware that the user needs to manage, which means the computer can communicate directly with connected peripherals via the available interfaces.
