Adafruit Feather M4 CAN Express with ATSAME51

Experience lightning-fast performance with the Feather M4 CAN Express, powered by the upgraded ATSAME51 chipset, boasting a 120MHz Cortex M4 with floating point support, 512KB Flash, and 192KB RAM.

Ideal for CAN interfacing projects, it integrates a built-in CAN bus, transceiver, and 5V booster. The 3-pin 3.5mm terminal block provides easy access to CAN signal lines and ground reference.

Effortlessly switch between Arduino and CircuitPython—plug it in, and it appears as a tiny disk with main.py. Edit with any text editor for seamless coding on any computer, including ChromeBooks.

Measuring only 2.0" x 0.9" x 0.28" and weighing 5 grams, it features robust connectivity with 21 GPIO pins, hardware SPI, I2C, Serial, DAC, ADC, PWM outputs, I2S input/output, and a parallel capture controller.

The additional 2 MB SPI Flash storage acts as your storage hub for Python scripts, libraries, or data logging, and can be accessed via Arduino for file reading/writing. Additionally, it includes a Mini NeoPixel, built-in lipoly charger, and multiple user-friendly features.

Easy reprogramming is facilitated by the pre-loaded UF2 bootloader, appearing as a USB storage key for drag-and-drop firmware updates without special tools or drivers.

Compact, powerful, and versatile, the Feather M4 CAN Express is fully assembled and tested, ready for your innovative projects. Headers for soldering and breadboard integration are included, though a Lipoly battery and USB cable are sold separately.
