RS485 CAN HAT for Raspberry Pi 5/4B/3B+/3B/2B/B+/Zero/Zero W/WH/2W, Long-Distance Communication via RS485/CAN Function, Onboard CAN Controller MCP2515, SPI Interface Transceiver SIT65HVD230DR

Easy setup on my Voron 2.4. Follow the online instructions and setup is a piece of cake.

The documentation that comes along with it is good. I was able to use this to test as a 2nd device to get my home brew can controller for a different device working. I needed one "known good" node to start, and this did the trick.

This made getting a CANbus connection to a tool head very easy.

Will not transmit data. The Modbus will with with the USB adapter but will not with the Hat

This hat was easy to add to the variety of the Pis I have (4B and ZeroW) and it works like a charm. My only complaints are that the male pin headers on the hat get bent easily when compared to a Raspberry Pi's and that the female pin headers can be a pain to mate. The documentation is actually quite good and even provides some ways to debug

I bought this expecting a some hassles getting it to work - sort of the standard for this low end stuff. I was sort of amazed how quick it was. There's a wiki page that explained how to change the Pi's config.txt to set up the CAN baud rate and a tar ball with some example code. Drivers were already in the Pi distro. I booted up the by and the device was there - set up some params for the SocketCAN interface with ifconfig, did a make on the example code, wired up a $500 Kvaser PC CAN USB interface, and it worked - both sending and receiving.A good deal.

easy to install and setup using the Openplotter OS. worked easily with a Raymarine Axiom 7 chart plotter, allowing me to get GPS to the Pi from the Axiom and AIS from the Pi to the Axiom. great value for money

Product seemed to be damaged before shipping, and did not function. Waste of time. Ordered a different, higher quality SPI CAN PCB for the sake of not wasting any more of my time.
