Zero 32-Bit SAMD21 Development Board with Embedded Debugger, Virtual COM Port and 3.3V UNO-Compatible Pinout

Zero is a 32-bit development board powered by an Atmel SAMD21 microcontroller with an ARM Cortex-M0+ core for embedded projects and 32-bit application learning.

Key Features

• Onboard Atmel Embedded Debugger provides a full debug interface without additional debugging hardware.
• EDBG also provides a virtual COM port for device and bootloader programming.
• Supports connection to a computer through micro-USB or external power from a compatible AC-to-DC adapter or battery.
• Works with shields designed for 3.3V operation and the Arduino 1.0 pinout.
• Suitable for IoT devices, wearable projects, automation, robotics and education.

Specifications

• Model / SKU: Zero, ABX00003
• Microcontroller: Atmel SAMD21
• Processor core: 32-bit ARM Cortex-M0+
• Operating voltage: 3.3V
• Debug interface: Onboard EDBG
