I recently reviewed this item but couldn’t figure out how to find/edit that review. I was having problems connecting via WiFi. I have since resolved the issue. The problem was unrelated to the CB2. It is functioning well now.

Absolutely love this board. Incredibly versatile, incredibly powerful. I have this set up with a CB1 and 2209s, everything works great. The manual does a good job at pretty much covering everything, albeit, not phrased the best. Nonetheless, super flexible board for endless possibilities. Love all of the fan controls, stepper driver options, UART mode, DIAG for sensorless, USB, ethernet, etc etc. It truly covers everything for a potentially awesome and big build. I see some reviews talking about "I thought this would include grub screws", or "Doesn't run the printer on USBC power", and - cmon people, it's a controller board. It includes JST connectors, which I wasn't expecting, so that's awesome. And USB C power? I understand a laptop, but you're running 24v heaters and motors, controller, etc, how would this work over USBC? There's no where they mention you can RUN this board with USBC. Like people, do a little digging! Yes, you can use USBC to program and config, it won't power fans, motors, heaters, etc, it's enough power to program things before setting things up. And that makes sense. Regardless, great board, I've been very excited about using it, and it's been fine configuring and optimizing things for my build. New found love for BigTreeTech

This is a great upgrade from the CB1. While I haven’t tested it with webcam decoding/encoding, it logically outperforms the CB1. I’ve have it running on a BTT Manta EZ3D, and it runs smoothly without issues. The GitHub page for the Kllipper image is actively maintained, which is a big plus—thanks to BTT for keeping the community supported!

It's a BTT product. All the corners that could be cut were cut, as is the tradition with BTT stuff. An Orange Pi or Banana Pi is a better bang for the buck performance wise. Also, when I asked some pointed questions about the pre-baked Armbian install to Customer Support, I got hand waving and vague explanations that didn't address the issue...as is the tradition with BTT stuff. So, I considered this a waste of time and money and promptly binned it...as is the tradition with BTT stuff.

Infinitely configurable for any situation you might need. I'm using it as a 8axis motion controller with Marlin Firmware. I used Klipper firmware initially and the software that BTT has provided is AMAZING. Not plug and play but very powerful. If you're just setting up klipper, BTT has provided an image for the CB1 module that includes klipper, klipperscreen, moonraker, mainsail, and crowsnest. Seriously good. Worth every penny.
