Adafruit Feather M4 CAN Express with ATSAME51
One of our favourite Feathers, the Feather M4 Express, is being upgraded to the SAME51 chipset, which has built-in CAN bus support!
Like its SAMD51 cousin, the ATSAME51J19 comes with a 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals to support it, this is sure to be your new favourite chipset for CAN interfacing projects.
At the end of the board, we have placed a CAN transceiver chip and a 5V converter in order to supply the transceiver with 5V even in battery operation. The two CAN signal lines and the ground reference signal are available on a 3-pin 3.5mm terminal strip. The chip and the booster can be put to sleep to save power. The built-in CAN read or write packets and has support in Arduino and CircuitPython.
And best of all, it’s a Feather – so you know it works with all of our FeatherWings! What a great way to get started quickly. It’s even pin-compatible with the original Feather M4.
The most exciting part of the Feather M4 CAN is that not only can you use it with the Arduino IDE – and it’s damn fast if you do – but you can use it with CircuitPython as well. When you plug it in, it shows up as a very small drive with main.py on it. Edit main.py with your favourite text editor to build your project in Python, the most popular programming language. No installations, IDE, or compiler are required, so you can use it on any computer, even ChromeBooks or computers that you can’t install software on. When you’re done, unplug the Feather and your code comes with it.
The Feather M4 Can Express also comes with a Mini NeoPixel and 2 MB SPI flash memory. You can use the SPI flash memory like a very small hard drive. When used in CircuitPython, the 2MB flash acts as storage for all of your scripts, libraries and files. When used in Arduino, you can read / write files to it, like a small data logger or SD card, and then use our utility to access the files over USB.
