Bigtreetech Adapter for CB1/CM4

This product includes only the adapter board for CB1/CM4 Compute Modules; the CB1 or CM4 modules must be purchased separately.  

Cost-effective option: Pairing PI4B Adapter with CB1, the function is close to the Raspberry-Pi 3B. With Bigtreetech motherboard, you can run the Linux system efficiently. The most value way using Klipper! When matching with the Raspberry Pi CM4, the function is exactly the same as the Raspberry Pi 4B.
