One of Adafruit's favorite Feathers, the Feather M4 Express, gets a glow-up here with an upgrade to the SAME51 chipset which has built in CAN bus support! Like it's 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 for support, this will for sure be your favorite new chipset for CAN interfacing projects.
At the end of the board Adafruit have placed a CAN transceiver chip as well as a 5V converter to generate 5V power to the transceiver even when running on battery. The two CAN signal lines and ground reference signal are available on a 3-pin 3.5mm terminal block. The chip and booster can be put to sleep for power saving. The built in CAN can read or write packets and has support in both Arduino and CircuitPython.
And best of all, it's a Feather - so you know it will work with all Adafruit's FeatherWings! What a great way to quickly get up and running. It's even pin-compatible with the original Feather M4.
The most exciting part of the Feather M4 CAN is that while you can use it with the Arduino IDE - and it's bonkers fast when you do, you can use it with CircuitPython as well. 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.
Here are some of the updates you can look forward to when using Feather M4 CAN:
The Feather M4 Can Express also comes with 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 Adafruit's helper program, access the files over USB.
Easy reprogramming: the Feather M4 CAN comes pre-loaded with the UF2 bootloader, which looks like a USB storage key. Simply drag firmware on to program, no special tools or drivers needed! It can be used to load up CircuitPython or Arduino IDE (it is bossa-compatible)
Comes fully assembled and tested, with the UF2 USB bootloader. They also toss in some headers so you can solder it in and plug into a solderless breadboard.
Lipoly battery and USB cable not included (but we do have lots of options in the shop if you'd like!)
