The MCP2221A is powerful and useful to have when the user wants to use Python, for example, to quickly iterate and test a device that uses I2C or general-purpose digital and analog I/O. No firmware is required. The user doesn't have to deal with how to send data to and from an Arduino, which is then sent to and from an electronic sensor, display, or part. This breakout includes an MCP2221A chip, USB Type-C connector, onboard 3V regulator, and 4 pin JST SH port for I2C connectivity with 3V power and logic. The port is Stemma QT/Qwiic compatible for use with any sensor or chip that has a matching port. The user can wire in Grove I2C devices with an adapter cable with no soldering required.
