Seeed Studio Seeeduino Cortex-M0+ Development Board ATSAMD21 ARM
Seeed Studio Seeeduino Cortex-M0+ development board with ATSAMD21 MCU, 48 MHz CPU, 256 KB flash, Arduino Zero compatible and USB Type-C.
The Seeed Studio Seeeduino Cortex-M0+ Development Board is a microcontroller platform built around a 32-bit ARM Cortex-M0+ processor. It is centred on the Microchip ATSAMD21 MCU and is fully compatible with the Arduino Zero, making it suitable for projects that require an Arduino-compatible board with a 32-bit core.
Overview
The board has a compact design measuring 43 mm (H) x 33 mm (W) x 15 mm (D) and weighs approximately 40 g. It provides 14 digital I/O pins, with 10 capable of PWM output, and 6 analogue input pins. Three on-board Grove connectors are included, two for I²C communication and one for UART, allowing straightforward connection to a range of sensors and actuators. The board can also be used with a Base Shield V2 to extend its connectivity.
