Adafruit Feather M4 CAN Express with ATSAME51

Adafruit Feather M4 CAN Express with ATSAME51 features the SAME51 chipset with built-in CAN bus support. The ATSAME51J19 comes with a 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. It has support for extra peripherals for CAN interfacing projects. The Feather M4 CAN Express also has a CAN transceiver chip and a 5V converter to generate 5V power to the transceiver when running on a battery. The two CAN signal lines and ground reference signal are available on a 3-pin 3.5mm terminal block.
