Best upgrade for my Voron
Installed this on my Voron 2.4 and the difference in interface responsiveness is night and day. Camera integration works flawlessly. It's powerful enough to handle multiple webcams if needed.

Solid hardware, minor WiFi quirks
The Ethernet connection is rock solid. WiFi works well generally, but I experienced occasional drops when the router was far away. Switching to wired solved it completely. Great value for the specs.

Excellent Raspberry Pi Alternative
With the scarcity of Raspberry Pis, this is a fantastic alternative. The GPIO pinout matches perfectly, and the build quality feels solid. The eMMC storage is much faster than relying solely on SD cards.

Great performance, runs a bit warm
The speed is impressive compared to my previous setup. I did notice it gets quite warm under heavy load, so I added a small fan to the case. Once cooled, it runs perfectly stable for days.

Easy for beginners
I was worried about setting up Linux, but this board made it effortless. The documentation provided by BIGTREETECH is clear, and the pre-configured software meant I was printing within 20 minutes of unboxing.

Perfect Klipper Host Out of the Box
This board saved me so much time. Flashing was unnecessary since it came ready with Klipper and Mainsail. The RK3566 chip handles high-speed printing without any lag. Highly recommended for anyone upgrading from an old Pi 3.
Q: How do I update the firmware if a new version is released?
A: You can update the system via the web interface (Mainsail or Fluidd) using the built-in update manager, or by SSH-ing into the board and running standard apt-get commands for OS updates.
Q: Is the GPIO header fully compatible with Raspberry Pi HATs?
A: The 40-pin header follows the Raspberry Pi physical layout and supports most GPIO functions. However, compatibility with specific HATs depends on their driver requirements and voltage levels.
Q: Can I install standard Ubuntu or Debian instead of the pre-loaded Klipper image?
A: Yes, since it uses the RK3566 chip, you can flash other ARM-based Linux distributions compatible with Rockchip processors, though you will need to configure Klipper manually.
Q: Does this board support input voltage higher than 5V?
A: No, the BIGTREETECH PI2 CB2 requires a stable 5V/3A power supply via USB-C. Inputting higher voltage may damage the board.
Q: What is the maximum resolution supported for the camera module?
A: It supports various USB webcams and CSI cameras. For USB webcams, it typically handles up to 1080p at 60fps or 4K at 30fps depending on the specific camera model and compression settings.
