Arduino Giga Can Transceiver

Projects Networking, Protocols, and Devices

Hi everyone,
I am currently looking into the Arduino Giga for a project but we would need Can bus for multiple gigas communicating. Since the giga does not have a can transceiver I was wondering if you have any recommendations on can transceivers available which work with the giga and are available in a breakout format.

Thanks in advance

Best regards

J

Depends on what feature set you need, for example, voltage isolation, a low power/sleep mode with wakeup, support for CAN-FD speeds, a dual voltage 3.3v/5v interface etc. etc.

If none of that matters then a SN65HVD230D direct from a reputable supplier will do the job.
Avoid Aliexpress, Amazon or Ebay as the market is flooded with poor quality fake chips.

Thanks a lot. Do you by any chance have a recommendation for one with the dual voltage interface and support for can-FD speeds?
Thanks again

What is "can-did"?
Post a link to the datasheet for the device.

Sorry I meant to say Can-FD

This works with Arduino Giga Wifi and Arduino UNO R4 Wifi:
Hardware:

  • 2 units of Giga Wifi or UNO WIFI R4 Wifi
  • 2x CAN bus SN65HVD230
    Note: You need 120R (Ohm) on each end of the bus as shown below.

Adafruit has the NXP TJA1051/T3 on a breakout board sold under the name "CAN pal".
That gives you 3.3v logic, a CAN signal at 5v and CAN-FD support.
