This is the new XIAO Arduino, a very interesting tiny (2cmx2cm aprox) microcontroller with the following features:
- Powerful CPU: ARM® Cortex®-M0+(SAMD21G18) running at up to 48Hz, 32KB of SRAM, and 256KB of onboard Flash memory
- Small Size: As small as a thumb(21×17.5mm) for wearable devices and small projects
- Easy Development: Supports Arduino / Micropython / CircuitPython
- Multiple development interfaces: 11 analog PINs, 11 digital PINs, 1 I2C interface, 1 UART interface, and 1 SPI interface
- Designed for production: Breadboard-friendly & SMD design, no components on the back
You need to install the Arduino IDE 2.0 and you can work following the screenshots of my installation in order to test the blinking code.
1- Add in Arduino> Preferences the link found in the image below to install this Seeedstudio board
2. After install go to Tools>Board manager and find and install XIAO Board
3. Choose the Seeeduino XIAO
4. Open and test the blinking code by changing the delay time in order to be sure that you control your board
