Adafruit Metro M4 feat. Microchip ATSAMD51

The Adafruit Metro M4 is engineered for high-speed, robust performance with its Microchip ATSAMD51 processor. This metro-like bullet train operates at a powerful 120MHz with a Cortex M4 that includes floating point support, ready to accelerate your coding ventures.

The familiar Arduino-compatible shape and pinout cater to effortless integration. With a compact design, it maintains compatibility with all existing shields. It offers precise placement of analog pins and consistent hardware support for SPI, UART, and I2C interfaces, mirroring the arrangement of the Metro 328 and M0.

Built with an ATSAMD51J19 processor, it features a 32-bit, 3.3V logic setup, a robust 512 KB flash, and 192 KB RAM. Additional technical specifications include dual 1 MSPS DAC and ADC, 6 SERCOM hardware communication modes, a wealth of 22 PWM outputs, and stereo I2S input/output.

The PCB board enhances capability with a variety of built-in features: a power supply flexibility between 7-9V DC and USB connections that seamlessly switch for convenience; a simple toggle with an on/off switch for easy control over the power setup.

This device is well-equipped with native USB support, eliminating the need for a separate converter. Utilize it as a serial device or manage code updates via the bootloader, capable of operating as an HID keyboard or mouse.

Equipped with onboard QSPI Flash, it enhances storage like a mini hard drive. Whether working in CircuitPython or Arduino, it aids in efficient file management. The UF2 bootloader streamlines reprogramming, offering simplicity akin to dragging files onto a USB drive.

With established support for Arduino and a trajectory toward running CircuitPython at peak efficiency, the Metro M4 creates seamless integration and expands your creative possibilities. Its capacity for running CircuitPython 3.0 is growing with each update, refining your development experience.
