Seeed Studio Seeeduino XIAO - Cortex-M0+ - SAMD21 - without Headers

The Seeeduino XIAO from Seeed Studio is a small but powerful microcontroller with an ARM Cortex-M0+ microchip. The XIAO has many I/O ports for its size, moreover it has 3 different interfaces including I2C and UART. Thanks to the USB-C port, this board is easy to program using the well-known Arduino IDE.

Seeed Studio is known for the easy connection of sensors and modules using the Grove connectors and cables. However, this XIAO does not have Grove connectors, but Seeed has a solution for this, namely the Grove Shield for Seeeduino XIAO.
