  • 🌱【Powerful CPU】 The Seeeduino XIAO is equipped with an ARM Cortex-M0+ 32bit 48MHz microcontroller, which is three times faster than Arduino Uno and Arduino Nano. Furthermore, this Arduino IDE compatible board XIAO has 256KB flash memory and 32KB SRAM.
  • 🌱【Rich Interfaces in a Tiny Size】 The device has 14 GPIO pins, each of which has 11 analog channels, 11 digital channels, I2C*1, UART*1, and SPI*1, USB Type-C interface*1 in a tiny space, just 20mm*17.5mm (about the size of your thumb). Seeeduino XIAO is the smallest Arduino compatible board in the Seeeduino series.
  • 🌱【Fully compatible with Arduino IDE】 Seeeduino XIAO development board is perfectly compatible with Arduino IDE and you can easily create small projects using the extensive and comprehensive Arduino library. It has a 2.54mm pin pitch and can be used even when inserted into a breadboard because it is an Arduino microcontroller.It has a 2.54mm pin pitch and can be used even when inserted into a breadboard because it is an Arduino microcontroller.
  • 🌱【Applications】 Seeeduino XIAO is suitable for Wearable devices, Rapid prototyping, DIY keyboard, USB to multi-channel TTL/USB host mode, etc.
  • 🌱【Perfect for Wearable and Tiny Arduino Projects】 This microcontroller has good performance in processing but needs less power. As a matter of fact, it is designed in a tiny size and can be used for Arduino wearable devices and small projects.
