Plug AX22 modules straight into an Arduino UNO. Four AX22 ports break out SPI, I2C, ADC, and GPIO from the UNO's headers into the standardized 22×22mm connector format. Drop in a sensor, display, or driver module and start coding. A reset button and onboard WS2812B NeoPixel round it out for quick prototyping and status indication.
This item does not include the Arduino Uno, only the shield.
