Arduino M0 Pro Development Board (formerly Zero Pro)
The Arduino M0 Pro Development Board is based on a 32-bit ARM Cortex® M0+ core and features the ATSAMD21G18 MCU.
Want to be more innovative with your designs? The M0 Pro is great for IoT (Internet of Things) projects due to it's powerful ARM Cortex® M0+ core, and introduces a number of ways to communicate with MCUs, computers, Arduino products and mobile devices.
The Arduino M0 Pro also benefits from an Embedded Debugger (EDBG) which eliminates the need for any additional hardware.
