BigTreeTech CB1 V2.2 Single board

Powerful Core Performance

The CB1 module is powered by a quad core Allwinner H616 processor (Cortex A53, 1.5 GHz) with a Mali G31 GPU—delivering efficient and reliable computation for embedded 3D printing tasks.

Memory & Multimedia Capabilities

With 1 GB of DDR3 RAM, the CB1 supports smooth multitasking and firmware operations. It offers HDMI 2.0A output capable of driving 4K displays, enabling high-resolution visual feedback.

Connectivity & Networking

Built-in 100 M Ethernet and 2.4 GHz Wi Fi (802.11 b/g/n) support both wired and wireless network connections, providing flexible control options.

Drop-in Compatibility

Designed with the same BTB (board-to-board) header and dimensions as the Raspberry Pi CM4, the CB1 can directly integrate with CM4-compatible carrier boards, including BigTreeTech Manta series mainboards, facilitating plug-and-play functionality.

Optimized for Klipper & 3D Printing

This board is ideal for running Klipper firmware, especially when paired with BTT’s Pi4B adapter or Manta motherboards like M4P, M5P, and M8P. The compact design and Linux/ Debian compatibility make it perfect for modern, high-performance 3D printer setups.
