EBB36 v1.2 without max amplifier from BTT.
Flashed by us with canboot and klipper.
It was flashed with can bus speed 500000.
How to wire the board?
How do I connect the Board?
If you have a BTT Octopus there is a guide to connect this can toolhead directly to the RJ11 of the board using a bridge mode.
Although we recommend to leave it alone (it’s too much complicated) and use a middleman such as U2C that we also sell. The U2c is like an interpeter that will convert and read the CAN data. U2c connects via USB-C to the RPI and the can toolhead board can be connected to the U2C via 4 cables only.
This meand that you will reduce your cable harness from 17 cables to 4 cables only!

Do I need to flash anything?
No. We sell all of our boards pre flashed.
