BIGTREETECH PI4B Adapter V1.0 for CM4 or CB1

I couldn’t be happier with my experience using BIQU products. The build quality is top-notch, performance is reliable, and everything just works as expected right out of the box. Customer service was also excellent — responsive, helpful, and friendly. Highly recommended for both beginners and experienced makers. Thanks, BIQU, for making such awesome tools for creators like me!

Used in an upgrade from arduino / marlin / pi to manta mp8/klipper/ CB1
Printer is a core xy with dual Z motor / hemera extruder / cr 10 bed type / proximity sens for Z. / HDMI display

The Manta board is versatile and the combo with klipper works great.
There are still more than sufficient connection / IO available for future expansions.

Did not use the on-board FET drivers for extruder heater and bed heater. Used external drivers, so can not really judge how the board handles a high load when its directly connected.

Thanks Bigtreetech

I bought the PI4B adapter board to make use of a CB1 board that I removed from my PAD7. The board will run Klipper on one of my 3D Printers. Very pleased.

It fits a standard printed Pi4 enclosure, pinout is Pi standard.
Enclosure cooling solutions won't fit, be attentive to this if you order a finished case.
The CB1 MPU gets quite warm and absolutely needs at least passive cooling with a glue-on heat sink.

I had no troubles setting it up. Works as expected.
