Product Profile
BIGTREETECH MANTA M5P is a 32-bit motherboard developed by the 3D
printing team of Shenzhen Big Tree Technology Co., Ltd. for Klipper running. It
can run Klipper with a core board, which greatly eliminates the mass wiring
between the motherboard and Raspberry Pi, and also greatly saves space in the
chassis. The BTB headers are designed on MANTA M5P, so that customers can
choose to use CM4 or other solutions, thus solving the insane shortage of
Raspberry Pi CM4.
Feature Highlights
1. 32bit 64MHz ARM Cortex-M0+ series STM32G0B1RET6 MCU.
2. The thermistor circuit is protected to prevent MCU damage from shorted
heated bed and heater cartridge connections.
3. The CNC fan's voltage is selectable in 24V, 12V, and 5V, no more need for
external stepdown thus preventing board damage from user error.
4. Thermistor connection supports pull-up resistance value setting using
jumpers, no more extra module needed for PT1000.
5. MCU firmware can be upgraded via an SD card, or use DFU via Klipper's
make flash command.
6. BTB connectors are adopted between the motherboard and core board,
allowing the choice of other core board solutions in addition to CM4.
7. Integrated SPI and UART mode of TMC driver and DIAG pin, easily
configurable with jumpers.
8. Support filament runout sensor, BLTouch, RGB, etc.
9. Replaceable fuse for easy maintenance.
10. Onboard proximity switch port, support NPN and PNP type selection, (24V,
12V, 5V) voltage selection.
11. Onboard SPI interface for connecting acceleration sensor to enable Klipper's
input shaping.
12. The new E-FUSE fuse is equipped, which can respond quickly, enhance self-
protection ability, and greatly reduce the motherboard burnout caused by
short circuits or ignition.

Connection Description
USB Power Supply
After the BIGTREETECH MANTA M5P has been powered, the red light D22 on
the left side of the MCU will light up, indicating power on. When using only the
USB to power the board or provide power through the USB, please insert the
jumper cap onto the VUSB.
Stepper Driver
STEP/DIR (STANDALONE) Mode
e.g.: A4988, DRV8825, LV8729, ST820, etc., connect jumpers(MS0-MS2)
according to the microstep chart.
Note: RST and SLP must be shorted by jumpers for A4988 or DRV8825.

Voltage Selection for CNC Fan
Through the jumper cap, you can set the output voltage to 5V, 12V, or 24V.
Note: We are not responsible for fan burnout caused by incorrect voltage selection.
Please confirm the voltage the fan supports before selecting the voltage.

100K NTC or PT1000 Setting
When using 100K NTC, no jumpers need to be connected, the pull up resistance
of TH0-TH3 is 4.7K 0.1%. When using PT1000, the pins indicated in the picture
below need to be connected via jumpers, parallel connection of 4.12K 0.1%
resistors, the pull-up resistance of TH0-TH1 is 2.2K. (This method has a much
lower accuracy than the MAX31865 in reading temperature.)

Raspberry Pi CM4 Usage Instructions
Download OS Image
When using CM4, download the image of Fluidd, Mainsail directly, also, you can
download a pure OS image from the Raspberry Pi official website and install it
yourself.
Fluidd: https://github.com/fluidd-core/FluiddPI/releases
