The Adafruit MCP2221A Breakout Board enables your computer to directly communicate with I2C devices, sensors, and LEDs, without needing an intermediary microcontroller like an Arduino or Trinket. This breakout board lets you easily interface with devices like tiny OLED displays, color sensors, and more, right from your computer.
Key Features:
-
MCP2221A Chip: A powerful chip from Microchip that acts as a USB-to-I2C bridge, adding GPIO and I2C interfaces to your computer.
-
GPIO Functionality: The analog/digital GPIO pins can function as 10-bit analog inputs (ADC) and even provide a 5-bit DAC output.
-
I2C Interface: Perfect for communicating with OLEDs, sensors, PWM drivers, and many other small devices that use I2C.
-
USB-to-I2C Communication: No need for firmware or complex setups; you can easily use Python or other programming languages to communicate with connected devices.
Easy to Use:
-
USB C Connector: Connects directly to your computer via a USB C port.
-
On-Board 3V Regulator: Powers devices with 3V logic and I2C connections.
-
STEMMA QT / Qwiic Compatibility: The breakout includes a 4-pin JST SH port, which is compatible with STEMMA QT and Qwiic devices, making integration with compatible sensors or chips easy, with no soldering required. You can even connect Grove I2C devices using an adapter cable.
Simplified Development:
- Perfect for quickly iterating and testing devices like sensors and displays, all without needing to manage separate Arduino or microcontroller setups.
- Great for projects that involve I2C, analog I/O, or general-purpose digital I/O.
With the MCP2221A breakout board, your computer can seamlessly talk to a wide range of sensors and devices, making it the perfect tool for rapid development and prototyping!
