PI4B adapter bigtreetech V1.0 for CB1 for motherboards used in 3D printer

• BIGTREETECH PI4B Adapter V1.0 for CB1 is a compact host platform made to run Klipper for 3D printers using BIGTREETECH and other compatible 3D printer motherboards.
• It combines the PI4B Adapter V1.0 carrier board with the BIGTREETECH CB1 compute module, and it also supports Raspberry Pi CM4—so you can choose between CB1 affordability and CM4 compatibility for your build in India. 
• At the core, the CB1 uses an Allwinner quad-core 64-bit ARM Cortex‑A53 @ 1.5GHz with 1GB DDR3 memory—strong enough to run Linux distributions like Debian for everyday printer hosting.
• This makes the PI4B + CB1 setup a practical alternative when Raspberry Pi boards are expensive or unavailable, while still providing the ports needed for screens, cameras, storage, and network access.
