BIGTREETECH MANTA M8P Mainboard

BIGTREETECH MANTA M8P is a 32-bit printer motherboard developed by the 3D printing team of Shenzhen Big Tree Technology Co., Ltd. for Klipper firmware.
You can simply plug in the core board to run the Klipper firmware, which greatly simplifies the connection between the motherboard and the Raspberry Pi, and saves a lot of space.
Moreover, the BTB connector is designed to install CM4 or other solutions to solve the current expensive problem of CM4.

1.1 Main Features

• Adopt 32-bit 64MHz ARM Cortex-M0+ series STM32G0B1VET6 as the main control chip;
• The power chip, TPS5450-5A, supports DC12/24V power input. The output current of the chip is up to 5A, and the peak value can reach 6A, which perfectly supports the power supply of Raspberry Pi;
• There is a BOOT button reserved on the motherboard, users can update the bootloader through DFU;
• The thermistor part includes a protection circuit that protects the main control chip from the possibility of burning caused by leakage of the heated bed or heater cartridge;
• 24V, 12V, and 5V voltages are available for CNC fans, eliminating the need for an external transformer module, thereby reducing the chance of damage to the motherboard due to improper operation;
• The thermistor can select the pull-up resistor value through the jumper, in this way, it supports PT1000 without an external module, which is convenient for customers to DIY;
• The MCU firmware can be updated via an SD card, or through Klipper's make flash command using DFU;
• The motherboard and the core board use the BTB connection to allow using other solutions other than CM4;
• On-board TMC-driver SPI and UART working modes, on-board DIAG function pins, can be used by simply plugging and unplugging the jumper cap;
• Support filament runout detection, auto shutdown, BLTouch, RGB lights...
• High efficiency MOSFET for less heat generation;
• Adopt replaceable fuse for easy replacement;
• Three-way four-wire fan interface is reserved, and can be used to connect the water cooling device;
• The proximity switch interface is reserved, supports NPN and PNP types, (24V, 12V, 5V) voltage selection is available, common voltage selection with VFAN6;
• Provide the SPI expansion interface to allow Klipper firmware users to connect an external acceleration sensor for acceleration compensation.
