- CB2 Core Control Board 2GB LPDDR4+32GB eMMC Storage Upgrade on BTT CB1 Support DSI/CSI Port Run Klipper Compatible with Raspberry-Pi 3B/4B Manta M8P/M5P/M4P/E3EZ Pi4B PAD 7 3D Printer Part

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!

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.

The first cb2 board I ordered would seem to boot but the HDMI wouldn't come up at all. I got an exchange for a new one and the HDMI worked fine. But, when I set the ArmbiENV and config.txt to enable DSI for a pi touch screen that was confirmed working with an actual raspberry pi, that screen would never come up and network port stops working. Massive headaches just trying to build a klipper pad and a complete waste of time.

The item was installed despite the confusing instructions from the company, most of which does not work as shown. I had to go online and find a video to complete the install. The company was emailed on their support line and finally got back to me saying they could not help unless I sent them a video along with the purchase information. Their support is far from helpful. It seems like they do not even read what you wrote for the problem. Problem is still not fixed, wifi does not connect, despite the light flashing to indicate it is on. Going on Github shows only one file for the component.

Running Klipper along with Manta M8P on a custom 3D printer. Works nicely so far. I will get another one for my new printer project as well.

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.

Great upgrade from the CB1! My wifi attena broke on my CB1 so I figured I'd try the CB2! Since the manta can't connect to my rsp pi 4b this was a great solution. It fits perfectly on the manta board, it's not the greatest price on here, it will help keep noise levels down since according to btt it doesn't need cooling, works and looks great with my hdmi5 display, and best of all it will help power my fancy chamber camera if I can ever get it to work with klipper lol. I'd highly recommend if you need a new pi but if your old CB1 is still kicking its really not worth the upgrade. This is 100% unnecessary but it works great! Edit: this is the second one that's had the wifi pin randomly fall off. It's really frustrating! I mainly use ethernet but that's beside the point. This should happen on multiple devices. Get your stuff together btt
