BigTreeTech U2C V2.1 USB to CAN Bus Module for EBB36/42

The BigTreeTech U2C V2.1 is a USB to CAN module that facilitates communication between your Raspberry Pi, BTT EBB36 or EBB42 CAN, and 3D printer mainboard.

 

Klipper, a popular open-source firmware, has revolutionized the 3D printing world with its ability to offload complex calculations to a single-board computer like the Raspberry Pi, enhancing print speeds and quality. If you’ve caught the modding bug like us, you can’t resist the opportunity to figure out how things work, so that you can make them work better. Makers eager to upgrade their printers quickly realise the potential of a powerful CAN bus connection, which you can use to install Klipper onto your 3D printer. With Klipper’s rising popularity, Makers have found ways of expanding their mainboards with this firmware using breakout boards and CAN-bus modules. This BigTreeTech U2C V2.1 is a USB to CAN module that serves as a crucial link in the communication when expanding to Klipper.

The BigTreeTech U2C V2.1 converts the USB port of Raspberry Pi to CAN bus for connecting your 3D printer mainboard and BTT EBB36 or EBB42 CAN. For mainboards such as the BTT Octopus Pro, this module drops in seamlessly with all the CAN interfaces you need for connecting through CAN bus. A long transmission distance and opportunity to mount many nodes make the BTT U2C V2.1 so versatile as a CAN bus module. Your motherboard, EBB, and other expansion boards can be mounted on the same CAN bus at the same time. The BigTreeTech U2C V2.1 has a total of three CAN output, providing a versatile solution for your Klipper expansion project.

As one of the rising stars in the world of 3D Printer Component Research and Development, BigTreeTech have certainly hit the ground running, entering the market in 2015 and spending their early stages primarily learning, researching, testing and developing, before producing some truly impressive results. From simple but effective upgrades to standard parts, all the way through to completely custom parts that no other brand offered at the time, BigTreeTech now have an incredibly diverse range, with almost no area of 3D Printing being left out.

Some of BigTreeTech’s most notable additions to the world of 3D Printing include the SKR Motherboard Range for numerous different 3D Printer models, the awesome TFT Touch Display Range with fancy features like dual-mode operation, as well as their very impressive Stepper Driver Range that cater to all tastes and preferences under the sun. And of course, to top it all off, BigTreeTech also have a sister company named BIQU, and we must admit that they have been producing some pretty impressive (and low price) 3D Printers, with the BIQU B1 possibly becoming a new rival to the Ender 3.

Of course, it’s easy to see that BigTreeTech are modern masters of 3D Printing R&D, and while we do still have a lot of different parts that we want to test out from them, so far we’ve been extremely happy with what they’re capable of producing – all while fitting into same kind of hobbyist budget that they used to operate on as Makers and Tinkerers themselves.
