Product Profile
BIGTREETECH Manta M8P V2.0 is a 32-bit 3D printer control board designed for
use with Klipper firmware. It allows direct installation of a core board to run
Klipper, greatly simplifying connections to a Raspberry Pi and saving space in the
electronics enclosure. The board has a BTB socket for use with a CM4, CB1, or
other solutions, providing flexibility beyond the expensive CM4.
Feature Highlights
Uses a 32-bit STM32H723ZET6 ARM Cortex-M7 MCU running at 550MHz.
The TPS5450-5A power chip supports 12/24V DC input and delivers up to
5A/6A peak for powering a Raspberry Pi.
A BOOT button is provided for DFU firmware updates.
The thermistor circuit is protected to prevent MCU damage from shorted
heated bed and heater cartridge connections.
PWM fans support 24/12/5V voltage selection without external transformer
module, reducing failure points.
The thermistor resistor can select the pull-up resistor value through a
jumper to support PT1000 without an external module, which is convenient
for customers to use for DIY purposes.
The MCU firmware can be upgraded through an SD card or through the
"make flash" command in Klipper to update the MCU firmware via DFU.
The BTB connector allows use of CM4, CB1, or other core boards.
The onboard TMC driver works in SPI and UART modes, and the onboard
DIAG function pin can be used by simply plugging in a jumper.
Connectors for filament sensor, auto power-off, BLTouch, RGB, I2C, servo,
5V power detection, etc.
High performance MOSFETs reduce heating.
Replaceable fuses for easy service.
3x 4-pin fan headers usable for water cooling.
Proximity switch header supports NPN and PNP (24/12/5V).
SPI expansion for accelerometer-based resonance compensation.
