Kit contents and purpose

This kit combines a BIGTREETECH CB1 V2.2 module with a Pi4B adapter panel board. It is designed for 3D printer builders who want to run Klipper firmware on compatible control boards without using a full Raspberry Pi unit.

Compatible control boards

The adapter fits SKR Mini E3 V3.0, Octopus V1.1, Octopus Pro and SKR 3 boards. The modular form lets you slot the CB1 directly onto the printer electronics, freeing up USB ports and removing the need for a separate single-board computer and its power supply.

Interfaces and connectivity

The Pi4B section provides Gigabit Ethernet, two HDMI ports, CSI and camera interfaces plus a 40-pin header. The CB1 module adds an HDMI 2.0a output, a USB 2.0 port and 100M Ethernet with Wi-Fi support for network access.

Highlights

  • Gigabit Ethernet on Pi4B for fast network printing
  • HDMI 2.0A on CB1 supports 4K display output
  • 40-pin header matches Raspberry Pi 4B layout exactly
