Wouldn't it be cool to drive a tiny OLED display, read a color sensor, or even just flash some LEDs directly from your computer?  Sure you can program an Arduino or Trinket to talk to these devices and your computer, but why can't your computer just talk to those devices and sensors itself?  Well, now your computer can talk to devices using the Adafruit MCP2221A breakout board! https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2021-04-06 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2021-08-19 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2022-08-17 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2022-09-01 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2022-10-14 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2022-10-21 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2022-11-21 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2022-12-01 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2023-03-13 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2023-03-14 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2023-03-15 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2023-03-16 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2023-03-17 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2024-11-27 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2024-12-03 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2025-02-22 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2025-03-03 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2025-04-26 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2025-05-12 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2025-08-08 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2025-08-21 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2026-01-30 https://elecena.pl/product/17500488/adafruit-mcp2221a-breakout-general-purpose-usb-to-gpio-adc-i2c 2026-02-16
