Introduction
The Adafruit Grand Central M4 Express is an Arduino mega format MCU board with an ATSAMD51 CPU, which is a 32-bit ARM Cortex M4 processor.
Licensing Information
The Adafruit Grand Central M4 Express is open hardware certified by the OSHWA - certificate reference US000247
Application: software and function
The Grand Central MCU will be deployed in a location away from the main demonstration, and will be used to test the second iteration of the sensor board prototype. Given that there are no network communications as part of the Grand Central, it is expected to be used with an Arduino Ethernet shield.
