Adafruit Grand Central M4 Express featuring SAMD51

Experience the powerhouse performance of the Adafruit Grand Central, energized by the Microchip ATSAMD51. Equipped with a 120MHz Cortex M4 with floating point support, watch your code execute with unprecedented speed and precision.

This robust development board mirrors the size and pinout of an Arduino Mega, giving you access to a massive array of pins, multiple analog inputs, dual DAC output, and other features such as:

• 1 MB flash & 256 KB RAM
• 8 MBytes of QSPI flash storage
• Dual 1 MSPS DAC & ADC
• 70 GPIO pins
• Stereo I2S input/output
• Built-in crypto engines

Power the Grand Central via a 6-12V DC jack or USB. Its built-in switch simplifies power management, seamlessly toggling between USB and DC input. The native USB support negates the need for a converter, and it can emulate a serial device or HID keyboard/mouse.

With 62 GPIO pins, this board supports extensive interfacing. Enjoy easy debugging with four indicator LEDs and a multi-purpose NeoPixel.

Unleash your creativity with the microSD card slot and 8 MB QSPI Flash, perfect for data storage and CircuitPython scripting. Easy to reprogram, thanks to its pre-loaded UF2 bootloader.

This technical marvel is designed for those demanding extraordinary power and flexibility, compatible with CircuitPython and Arduino IDE, opening endless possibilities in your projects.
