Adafruit 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, resulting in an ultra-thin, lightweight board. The board features a Cortex M4 Core 120MHz Arm® microcontroller with floating-point support. Grand Central has 62x General Purpose Input Output pins. Of those pins, 16x are analog in, and 2x are true analog out. The board also has an SPI port, I2C port, and UART. The board supports CircuitPython or Arduino IDE libraries for wireless integration and building Internet of Things (IoT) projects. The board also includes an 8MB QSPI Flash storage chip.Features
