## Description

BIGTREETECH U2C V1.1 Adapter Board Supports CAN-Bus Connection, with 3 CAN Output Interface

Review: easy usb to canbus adapter - good for usb-to-can adaptation in a voron 2.4, if you want to go this route. it's not really necessary in most builds i think, but regardless it's held strong and has no issues.. except for accidentally running 110v directly into the first one and burning it up. don't do that and you'll be fine.
Review: Works great! - Works great to add CAN Bus to 3d printer mainboards that dont have these connections! Easy to configure and install, no janky MacGyvering of wires

## Features

- Support CAN-BUS connection. With rich CAN interfaces: U2C V2.1 has 3 CAN output interfaces
- Why do U2C? More functions can be realized through the transfer, which can realize "multiple connections at one time", which is faster and more efficient
- TYPE-C interface ESD protection to prevent static electricity from damaging the hardware
- Support firmware update for the master through SWD or hardware DFU
- The PCB surface of the U2C adapter board adopts immersion metal work, and the quality is more premium

## Questions & Answers

**Q: ac or dc?**
A: I prefer Motley Crew.  But the board uses DC

**Q: Whats the difference between "v1.1"  &  "v1.1 only"  ?  thanks**
A: v1.0 had minor silkscreen errors which mislabeled a pin on the underside of the board. I think the v1.1 may include some of that stock, while 'v1.1 only' would only be the updated model.

**Q: Does this require a Raspberry pi to print or can it just be connected to a computer?**
A: If you run Marlin or reprap firmware then no you do not need a raspberry pi.  If you intend to use klipper then a pi is a requirement.  By default I believe it comes with Marlin.

**Q: what firmware is pre installed with this board and can it be used without upgrade?**
A: I don't think any firmware is installed from factory. It has to be downloaded from big tree's website or other and installed on the board.

### ⭐⭐⭐⭐⭐ Flawless (if you can get through BTT instructions)
*by S***T on February 20, 2023*

Instructions on BTT github are poor, but once through that, it's a flawless addition to 3d printer. Flash with Candlelight firmware noted in instruction doc and you are done.
