The other half is a single-board computer to host the firmware, and the price of a Raspberry Pi Compute Module has spent the last several years swinging between scarce and expensive. The CB1 Carrier exists because that second purchase does not have to be a Raspberry Pi at all.\u003c\/p\u003e\n\u003cp\u003eIt is an adapter board that accepts the BIGTREETECH CB1 core module and presents it to printer motherboards in the familiar Compute Module form factor. That means a CB1 can drop into the socket on an Octopus or an SKR Mini E3 v3.0 and be treated by the board as though it were the module the socket was designed for. The adapter adds the connectors the printer build actually needs: network, USB and display headers, brought out to accessible positions on the board edge.\u003c\/p\u003e\n\u003cp\u003eThe practical effect is a lower bill of materials for a Klipper conversion. The CB1 module is a capable Linux host for Klipper, running the same firmware stack and the same configuration workflow. It handles input shaping calculations, a camera stream if you want one, and Moonraker or Fluidd without strain. What it does not do is carry the Compute Module price premium, or the availability problem that comes with it.\u003c\/p\u003e\n\u003cp\u003eThe adapter also makes a good spare. Keeping a second host module on the shelf means a failed compute module is a ten-minute swap rather than a stalled print farm and a two-week wait for stock.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThe firmware does not care whose name is on the processor.
