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

Worked great in my Voron 2.4 with Klipper and Katapult, I have not tried the 48V power for A and B but looking forward to trying that when I get TMC5160 drivers for that. The 5/12/24V for the fans is very nice to have so I could use fans I already had and didn't need to buy more. The only real complaint that I have is that the board uses RJ46 for CANBUS when everything other than Duet uses a normal 2 pin JST connector. Other Bigtreetech boards use it to and an adapter is not included which I had to order seperately when I used a CANBUS board for the toolhead.

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.

Bought this as a spare or possible 2nd printer build. The one in my printer has been running for about 2 years flawlessly.

The documentation from BigTreeTech is terrible! I also could not get it to work out of the box and had to reflash the firmware. However the saving grace is the 3d printing community has stepped up and created a good number of resources. Furthermore You can flash Catapult and Klipper on it and then it will work as intended.I haven't done enough testing yet to know if it is reliable long turn.

I was happy with this CAN adapter. I used it to help isolate a CAN bus issue I was experiencing with one of my Voron builds (I used it to bypass the on-board CAN bridge on the Octopus board). In the end I ended up leaving this board in place on that build, and it has performed without issue.

I'm converting an Ender 5 to have 4 extruders and a Zonestar M4V6 4in-1out mixing hotend. Most mainboards don't have at least 7 stepper drivers (X,Y,Z,E1,E2,E3,E4), but these do. You'll be building your own firmware for it, which will be a bit of work, but once you have it all set up, it'll work great. It'll give you more ports for doing dual Y and/or Z too.If you haven't done your own Marlin firmware before, it'll probably take you a couple days to go through all the decisions on where to put things, and configure the Configuration*.h files. Not impossible, just a little time consuming. It doesn't even require programming, just the ability to read plain English words, and pick the options.The biggest caveat that isn't documented is, you have to use a small SD card with it. It can't read any of my larger CF cards. That took me a while to discover. I'm using a 128MB card, which does work. I really don't have many cards less than 32GB, so I really had a hard time finding one. So when you can't flash the firmware, or read the card for gcode, go get a *smaller* SD card.

I updated to firmware first thing, then was able to use it with my EBB with no issues

Using it what it was intended for, a way to add CAN bus to my Voron2. Connected 24Vdc to power it, routed it to my PI via USB, wired CAN TX RX to the toolhead wires provided for my EBB RP2040 from BTT. Was talking to it as soon as I configed my PI using Katapult software.Make sure you go to BigTreeTech's GIT page and download the assets for the project used in conjunction of whichever path you chose for upgrading your toohead.

This Company comes up with the products you want, but other than the hardware, everything else is lacking. Their support for their products is spotty at best! You are basically on your own to figure out how to make their products work(even in conjunction with their own products). Their customer support is hit or miss, and they often show product in stock that in reality aren't. This results is unknow and uncommunicated delays, and when you finally realize you have to reach out to see where your stuff is, the response is very apologetic, but lacks any real information or details about when you might actually receive the parts they originally told you were in stock and ready to ship. Again, Good hardware....Bad everything else!!

Worked with klipper right out of box, only thing if using canbus over USB (SKR3 mini e3 for example on PA 11/12 make sure to use VBUS jumper on the u2c (for respective port 1/2) the manuaal sucks but the product is amazing, came flashed with candlelight zero config. running EBB 42 MCU, SKR3 mini E3 MCU, and RP2040 with can transceiver running my filament heater box/ filament sensor, and ventilation/dampers
