Question1:Can't send and receive data? Answer: 1.Make sure the baud rates on both sides are the same; 2.The fixed frame ID is set in the routine: 0X123, please set the sending and receiving CAN ID of the other end of your CAN to be x0123; Question2:How to configure the config.txt file when the Ubuntu system is installed on the Raspberry Pi? Answer: 1.Mainstream Ubuntu system config.txt files are usually in the /boot/firmware folder 2.Or use the SD card of the Raspberry Pi to read and change the config.txt file under the computer (or other host that can recognize the SD card) through the card reader.

Review: Used it to connect NMEA2000 boat network to a Raspberry Pi - 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
Review: Nice setup - Easy setup on my Voron 2.4. Follow the online instructions and setup is a piece of cake.

## Questions & Answers

**Q: The unit i received has a 12mhz crystal, the unit in the picture and in the docs has an 8mhz crystal. please update docs?**
A: Hi, Thanks for your suggestion, we will update it.

**Q: I want to be able to monitor and transmit CAN transmission on my Snapmaker 3D printer with a PI4B. Will this work? Do I need anything else?**
A: If you connect this board to your Pi and connect the board to a properly terminated CAN bus to your printer, you should be able to use the Linux SocketCAN interface to talk to the printer.  I looked the Snapmaker and there is some sort of CAN hub you can use to make a connection.  Passively monitoring is more tricky - that's best done with a specific tool such as a Kvaser analyzer or a logic analyzer if you pick off the CAN signals after they have been converted from CANH/CANL by a logic transceiver.  The CAN board does support direct connection to the CAN network, and there is a lot of sample code on the web on how to bring up SocketCAN with ifConfig on it.

**Q: Will this work with a raspberry pi pico w**
A: Yes

**Q: Is there a C/C++ api for this thing? I'm not getting this obsession with using Python.**
A: You use Linux SocketCAN.  Once Linux brings up the interface with ifConfig, you can use regular BSD Socket Calls from wherever you like.

### ⭐⭐⭐⭐⭐ Nice setup

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

### ⭐⭐⭐⭐⭐ Worked the first time on a Raspberry Pi
*by T***M on June 15, 2020*

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.
