Core control board for Klipper 3D printing

The WaveShare BIGTREETECH CB1 V2.2 is an IoT edge development board built around a quad-core 64-bit ARM Cortex-A53 processor running at 1.5 GHz with 1 GB of DDR3 memory. It targets makers who want to run Klipper firmware on compatible 3D-printer motherboards such as the Manta M8P or M4P. The board uses the same BTB header layout as a Raspberry Pi CM4 so it can be paired with a Pi 4B adapter board.

CM4-compatible BTB header decides fit

The single specification that determines whether this board will work in your build is the CM4-style BTB connector. If your printer motherboard provides that exact header, the CB1 slots in directly; if the header is absent or a different pitch, the board cannot be used without a custom adapter.

Runs Linux on a Pi 4B carrier

When mounted on a Pi 4B adapter the module exposes HDMI 2.0a for 4K output, a USB 2.0 port, onboard 100 M Ethernet and 100 M Wi-Fi. It boots standard Linux distributions such as Ubuntu, freeing the host computer from real-time printer duties while the Mali G31 MP2 GPU handles OpenGL 3.2 graphics for any local interface.

Questions about this item

How does the 1.5 GHz quad-core Cortex-A53 perform when running Klipper on a 3D printer?

The board delivers Raspberry Pi 3B-class performance, which is sufficient for Klipper host duties, input shaping calculations and typical webcam streaming on a printer.

What practical limit does the onboard 100 Mbit/s Ethernet impose?

The 100 Mbit/s wired interface limits network throughput to that rate, so large file transfers or high-bitrate streams will be slower than on a gigabit link.

What physical connector does the CB1 V2.2 use to mount on a Pi 4B adapter or Manta motherboard?

It uses the same BTB header as a Raspberry Pi CM4 module, allowing direct insertion into compatible carrier boards.
