1 Brief Introduction
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
1. Adopt 32-bit 64MHz ARM Cortex-M0+ series STM32G0B1VET6 as the main
control chip;
2. 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;
3. There is a BOOT button reserved on the motherboard, users can update the
bootloader through DFU;
4. 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;
5. 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;
6. 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;
7. The MCU firmware can be updated via an SD card, or through Klipper's make
flash command using DFU;
8. The motherboard and the core board use the BTB connection to allow using
other solutions other than CM4;
9. 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;
10. Support filament runout detection, auto shutdown, BLTouch, RGB lights...
11. High efficiency MOSFET for less heat generation;
12. Adopt replaceable fuse for easy replacement;
