Description of Enhance Communication Range with RS485 CAN HAT for Raspberry Pi 4B/3B+/3B/2B/B+/A+/Zero/Zero W/WH

RS485 CAN HAT for Raspberry Pi, Allows Stable Long-distance Communication.It is compatible with Raspberry Pi 4B/3B+/3B/2B/Zero/Zero W/Zero WH.The RS485 CAN HAT will enables your Pi to communicate with other devices stably in long-distance via RS485/CAN functions. CAN function, onboard CAN controller MCP2515 via SPI interface, onboard transceiver SN65HVD230. RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard transceiver SP3485. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit for RS485 transceiving, lightning-proof & anti-electrostatic. Operating voltage: 3.3V. CAN controller: MCP2515. CAN transceiver: SN65HVD230. 485 transceiver: SP3485. Dimension: 65mm x 30mm. Mounting hole size: 3.0mm. Reserved control pins, allows to work with other control boards.Comes with development resources and manual (examples in wiringPi/python).

Worked on a Raspberry Pi for the first time

I bought this expecting some issues to get it working - sort of standard for this low end device. I was a little surprised at how quick it was. There is a wiki page that explains how to modify the Pi's config.txt file to adjust the CAN baud rate and tarball with some sample code. The drivers were already included in the Pi distribution. I downloaded it and the device was there - configured some settings for the SocketCAN interface with ifconfig, created the sample code, plugged in a $500 Kvaser

Pros
  • cool
Cons
  • too dumb

Need better documentation but worked fine

Worked like a charm when I figured it out. It took me a while to realize that the documentation available on the internet on Rs485 stuff was pretty sparse.

Pros
  • Pleasing
Cons
  • Other

Clean packaging with compromises

Stacking design is very desirable although the female connector is very difficult to remove once on, mine is very tight. The 120 ohm terminator is soldered onto this board, not as a jumper on other designs. It's annoying to have to desolder the SMD resistor if I want to have more than two devices on my network. The software support is good and the instructions are clear and easy to follow.

Pros
  • High marks for grip and durability from testers
Cons
  • Fairly ok

Pros
  • Very good price
Cons

Used to connect NMEA2000 boat network to Raspberry Pi

Easy installation and configuration with Openplotter OS. Worked seamlessly with a Raymarine Axiom 7 chartplotter, allowing me to transfer GPS to Pi and AIS from Pi to Axiom using Axiom. Excellent value for money and quality

Pros
  • . Satisfied so far
Cons
  • sad packaging

The stacking design is very desirable although the female connector is very difficult to remove once on, mine are all very tight. The 120 ohm terminating resistor is soldered onto this board, not the adjustable jumper on other versions. It's annoying to have to desolder the SMD resistor if I want to have more than two devices on my network. The software support is good and the instructions are clear and easy to follow.

Pros
  • Good workmanship
Cons
  • No
