Nice RS485/CAN Hat

I'm in the process of adding NMEA2000 gear on my boat for the first time, so I've been on the lookout for a CAN hat. I was already using a WaveShare dual-channel RS-485 hat, and originally tried another WaveShare dual-channel CAN hat. It did work, but I didn't like the idea that I literally had three hats stacked on top of my RPI.

I looked at the PICAN hat, but it seems a little bit expensive and doesn't include RS485. I did see the little CAN/RS485 hat from WaveShare, but it only has a single RS485 interface, and I need two.

So, I found this from Innomaker. It's an isolated two-channel RS-485 and single-channel CAN hat. It seems well built, the screw connectors are nice and large and it was easy to set up. Much cheaper than a PICAN hat, and it includes RS485.

Nice little board for those who have both NMEA0183 and NMEA2000 onboard. In my case, I'm even bringing some ancient SEATALK stuff in, and thanks to the excellent work by Teppo and the rest of the SignalK team, it all comes together flawlessly.

Just thought I'd pass this along.


Interesting. One thing I do like about the PiCAN-M is that it powers the Pi off the NMEA 2000 network, rather than needing a separate power supply.
