Product Description An Innovative and Easier Way to Run Your Klipper Manta M4P/M5P/M8P are born for Klipper running, they allow a direct installation of the BIGTREETECH CB1/Raspberry Pi CM4 to run the Linux system, then the Klipper. Board-to-Board Connector Designed with the same connector as Raspberry Pi, giving you a confident connection with all versions of CM4, and definitely, CB1 or CB1 eMMC. A screw-reinforced installation is available, too. Compatibility & Extensibility *Note: •The HDMI, TFT35 SPI, and USB Camera can only work with CB1.•The CSI/DSI port can only work with CM4. Functions & Application Manta M4P ✅ Installed with 32-bit 64MHz ARM® Cortex-M0+ STM32G0BORE chip, more stable and faster. ✅ Designed with the same connector with Raspberry Pi, giving you a confident connection with all versions of CM4,definitely, CB1. Also, a screw-reinforced installation is also avaliable. ✅ TPS5450-5A Power Chip The 5A output perfectly matches the power supply need of Raspberry Pi. ✅ It has rich expansion ports, can support various expansion modules, such as BL Touch, LCD screen, RGB light, auto shutdown, etc. 🌟The M4P & CB1 can be the best choice for Voron V0, Ender 3 etc. Manta M5P ✅ Installed with 32-bit 64MHz ARM® Cortex-M0+ STM32G0B1RET6 chip, more stable and faster. ✅ Designed with the same connector with Raspberry Pi, giving you a confident connection with all versions of CM4,definitely, CB1. Also, a screw-reinforced installation is also avaliable. ✅ It has rich expansion ports, can support various expansion modules, such as BL Touch, LCD screen, RGB light, auto shutdown, etc. ✅ TPS5450-5A Power Chip The 5A output perfectly matches the power supply need of Raspberry Pi. ✅ Selectable CNC fan voltage, 5V/12V/24V. ✅ Added eFuse circuit protection. It will faster disconnected on overload, and automatically reset if the overload is gone, which will greatly reduce the motherboard burnout caused by short circuits or ignition. ✅ Reserved Can Bus port can be connected with EBB CAN, which will simplify the wiring and provide strong  anti-interference ability. 🌟The M5P & CB1 can be the best choice for Voron V0, Ender 3, etc. Manta M8P V1.1 ✅ Installed with 32-bit 64MHz ARM® Cortex-M0+ STM32G0B1VET6 chip, more stable and faster. ✅ Designed with the same connector with Raspberry Pi, giving you a confident connection with all versions of CM4,definitely, CB1.
