BIGTREETECH BTT PI4B Adapter for CB1

PI4B uses a compatible interface with CM4 which can be installed directly on the PI4B (board to board).

In addition, the PI4B uses the same mounting hole and interface as the Raspberry Pi 4B, so the PI4B with CM4 installed can be used as a replacement for the Raspberry Pi 4B.

PI4B+CB1 with its high cost performance can become a cheap option for 3D printer users who use conventional motherboards to run Klipper firmware.

The modularity of the PI4B and CM4 make them suitable for DIY use

Features

• Same mounting hole locations as the Raspberry Pi 4B
• Supports different versions of CM4 modules
• Interfaces: Gigabit Ethernet, HDMI0, HDMI1, CAM, CSI
• Equipped with ESD protection on USB and network interfaces
• 40-pin dual-row header with the same function as the Raspberry PI
• Uses a Type-C interface that can be used to connect both eMMC and power
• Dedicated 5V power interface that can be connected to the CM4's 5V heat dissipation fan

Please note

• It is not possible to connect a PI TFT screen to the CB1. The DSI/CSI port will only work when using the CM4.
• PI4B must be used with CB1 or CM4 in order to run the Klipper firmware
