seeed studio CAN-Bus Shield V2 Compatible with Arduino

Months of tinkering with other mcp2515 boards, changing crystals to 16MHz, trying different libraries, starting over, buying a knock off shield, all didn't work trying to talk to megasquirt via can bus. finally this seeed studio can shield and an arduino UNO knock off is working.

Worked perfectly! Was able to use this shield to open and close my homemade truck bed cover using my OEM key fob by intercepting CAN messages.

works good with the Arduino giga and mega, and good documentation

The item arrived on time. I uploaded a test program and ran it but have not hooked it up to my car's OBD2 port yet but i am sure it works fine

I am still pretty new to arduino and soldering stuff. I was also thinking the saulders were missing. I checked them with the multimeter and some were connected even though I could not visually see it. I use the box cutter to separate them all and confirmed that with a multimeter. I soldered them all back mostly to default except for the can bus that I did not want on obd2. The supporting documentation is terrible on the website but I did manage to find a "v2" document that actually looked like the "v2" that I had received. I did lots of extra Googling and finally got it working. All the defaults worked with my mega 2560 r3. I think there's some other can bus shields out there that have better documentation and would have been a better choice. You can also just buy the individual parts and build it yourself. I needed something quick and it worked so it's good with me.
