BIGTREETECH Manta M5P V1.0 32Bit Control Board Support 5 Axis TMC2209 TMC2208 Stepper Drivers Compatible with CB1/CB2/CM4 to running Klipper for Ender 3/Voron V0, CoreXY, I3 3D Printer DIY Motherboard

So its a great idea... but not executed well. I mean No fussing with power supply's, not having to pay for a Raspberry Pi, all on board and Can Bus to boot. Wonderful idea, but doesn't work.CB1 is a poor excuse for a CM4 just in Wi-Fi alone, if your running Klipper screen on anything but there SPI screen you need a Raspberry Pi anyway. The CB1 would work than it would update and not work, spotty at best when it did work having to reset and try to upload your g-code before it failed... reset and try again. In the end I ended up buying a CM4 at the scalpers price just to get the Wi-Fi to work. BTT claims it was fixed and well I beg to differ. I have yet to find documentation on the Can Bus, and will be buying a FYSETC can bus module on principle alone.

I bought this board because it has an onboard CAN bus. I had been using a SKR Pro v1,2 with a Raspberry Pi, and BTT U2C board to connect my printer to a BTT EBB36. BigTreeTech doesn't provide any information on how to configure this board with Klipper to use the onboard CAN bus. In fact, in one discussion I saw BTT say they had "solutions" that uses the Manta M8P, U2C and EBB. It seems like they don't know how to configure it for use.Also, the CB1 has issues with basic functionality. One problem I am having is with configuring an HMDI display. I can set the OS to get the right resolution, but applications like KlipperScreen is given the wrong information.
