Seeed Studio Seeeduino Cortex-M0+ Development Board ATSAMD21 ARM

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.

Key Features

• Microcontroller: Microchip ATSAMD21G18 with ARM Cortex-M0+ core
• CPU speed: Up to 48 MHz
• Memory: 256 KB of in-system self-programmable flash and 32 KB of SRAM
• Analogue capabilities: 12-bit ADC with up to 20 channels at 350 kSPS, and a 10-bit DAC
• USB Type-C port for power supply and data communication
• Compatible with the Arduino Zero and Base Shield V2

Applications

The board is ideal for prototyping, educational purposes, and IoT applications. Its Grove connectors and digital and analogue pins support projects that interface with sensors and actuators, while the Base Shield V2 can be used to add further connectivity. It provides a foundation for developers and hobbyists working on embedded projects.
