Grand Central M4 Express Evaluation Board

Adafruit Grand Central M4 Express Evaluation Board is a development tool that evaluates the Microchip ATSAMD5. The board features the SAMD51 microcontroller without headers. A board without headers is ultra-thin and lightweight. The board has a Cortex M4 Core 120MHz Arm microcontroller with floating point support. Grand Central has 62 General Purpose Input Output pins. Of those pins, 16 are analog in and two are true analog out. The board also has a hardware SPI port, hardware I²C port and hardware UART. The board supports CircuitPython or Arduino IDE libraries for use in wireless integration and in the building Internet of Things (IoT) projects. The board also includes an 8MB QSPI Flash storage chip.
