Adafruit Feather M4 CAN Express with ATSAME51 (ADA4759)

This is a placeholder topic for “Adafruit Feather M4 CAN Express with ATSAME51” comments.

One of our 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 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 for support, this will for sure be your favorite new chipset for CAN interfacing projects.

What is the warranty on these? Cheers.

Right thanks, so since Adafruit products don’t appear to be manufactured/handled in an ESD safe manner, except for the final packaging I assume 90 days?

“Low-cost hobby-grade parts that are subject to casual mishandling in favour of convenience are often covered by a 90-day warranty unless there is sufficient evidence of a static-safe work environment”

Hi Ingmar :slight_smile:

Adafruit make good quality stuff! Their feather products all come with a 12-month warranty.

If you do run into any warranty issues, you can always make a post here so we can run through some troubleshooting or reply to your order confirmation email and we’ll get you sorted ASAP.

They do, I AGREE and they would be even better if they understood ESD safe manufacturing and handling practises :wink: [yes, i know it’s a dig but the various “inside” videos speak for themselves]


Hey Oliver,
I see the M4 CAN have been dropping like flies with the NEO having predictably killed PB03 of the SAME51 (ref their forums). Do you know if a new fixed batch is planned? I’d like to get one of the “fixed” ones.

Hey Ingmar,

Unfortunately we haven’t heard anything from the team over at Adafruit, it looks like a lot of their issues regarding this have only been in the last few weeks.

I’m sure they will be able to provide a solution ASAP, until then it is just a bit of a waiting game I’m afraid. If you had any other questions in the meantime don’t hesitate to ask.
