Sure, you can program an\nArduino or Trinket to talk to these devices and your computer, but why can't\nyour computer just talk to these devices and sensors itself? Well, now your\ncomputer can talk to devices by using the Adafruit MCP2221A Breakout Board.\nWhat can the MCP2221 chip do? This chip from Microchip is similar to a USB to\nserial converter chip, but also adds a GPIO and I2C interface. The\nanalog\/digital GPIO pins can act as 10-bit analog inputs (ADC) and there is\neven a 5-bit DAC output. The I2C interface is great for talking with OLEDs,\nsensors, PWM drivers, is the most popular interface for small devices. You can\nuse the GPIO to do things like flash LEDs, read switches or buttons, and much\nmore. The MCP2221A Breakout is like a small Swiss army knife for serial\nprotocols on your computer. This chip is powerful and useful if you want to\nuse Python (for example) to quickly iterate and test a device that uses I2C or\ngeneral digital and analog I\/O. There is no firmware to deal with, so you\ndon't have to deal with how to \"send data to and from an Arduino that is then\nsent to and from an electronic sensor or display or part\". This breakout\nfeatures an MCP2221A chip, USB-C port, built-in 3V regulator, and a 4-pin JST-\nSH connector for I2C connectivity with 3V power supply and logic. This\nconnector is Stemma QT \/ Qwiic compatible for use with any sensor or chip that\nhas a matching port - you can even wire Grove I2C devices with an adapter\ncable without soldering.
