Description:

The Adafruit Feather M4 Express is a powerful and versatile development board based on the Microchip ATSAMD51 microcontroller. It’s perfect for projects that require more processing power, memory, and connectivity than smaller boards. This Feather comes with 512KB of Flash and 192KB of RAM, a 120MHz Cortex M4 processor, and built-in USB support. It’s designed to be easy to use with the Arduino IDE and CircuitPython, making it a great choice for beginners and experienced makers alike. The Feather M4 Express includes a wide range of peripherals, including multiple timers, UARTs, I2C, SPI, and analog-to-digital converters, allowing you to connect to a variety of sensors and devices. Its compact Feather format makes it ideal for portable and embedded applications.

This is Adafruit Feather M4 Express – Featuring ATSAMD51 – ATSAMD51 Cortex M4.

Welcome to the most powerful Feather made to date: The Feather M4 Express. This Feather is powered by our favorite new chip, the ATSAMD51J19 – a 32-bit 120MHz Cortex M4 processor with floating point support, 512KB Flash, 192KB RAM.

The Feather M4 ships with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with main.py on it. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can’t install software on. When you’re done, unplug the Feather and your code will go with you.

Want to use it with Arduino instead? The Feather M4 can be used with the Arduino IDE – and it’s bonkers fast when you do. Just follow the Adafruit guide on setting it up with Arduino and it is ready to go!

The Feather M4 Express also has a mini NeoPixel and 2 MB SPI Flash storage. You can use the SPI Flash storage like a very tiny hard drive. When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB.
