BIGTREETECH Manta M4P

Note:

1. The CB1 couldn’t be connected to the PI TFT Screen.

2. Manta M4P/M8P should be used with CB1 or CM4 core board to run Klipper.

1. Brief Introduction

BIGTREETECH CB1 is an alternative to Raspberry Pi CM4. BIGTREETECH M4P is a 4-axis motherboard using a CM4 BTB header, which can work with CB1 or CM4 perfectly.

BIGTREETECH MANTA M4P 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.

2. M4P Main Features

1. DSI1, CSI1 interface (for CM4)

2. Gigabit Ethernet interface (1000M for CM4, 100M for CB1)

3. 3 USB 2.0 ports

4. Equipping the ESD protection chip on the USB and Ethernet ports to prevent being broken down by the static electricity

5. When working with Raspberry Pi CM4, its 40pin pin header has the same function as that of Raspberry Pi(Custom IO for CB1)

6. Using a BTB board-to-board connection, which can be further reinforced with screws, perfectly compatible with CB1 or Raspberry Pi CM4

7. The MCU adopts STM32G0B0RE 32-bit ARM Cortex-M0+ @64MHz chip

8. The power chip adopts TPS5450-5A, which 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 the core board.

9. The protection circuit of the thermistor part prevents the main control chip from burning due to leakage of the heated bed or heater cartridge.

10. MCU firmware can be upgraded through SD card, or through DFU with Klipper’s make flash command.

11. On-board TMC-driven SPI and UART working modes, on-board DIAG function pins, can be used by simply plugging and unplugging the jumper cap

3. CB1 Main Features

1. CPU: Allwinner H616, Quad-core Cortex-A53 @1.5GHz

2. GPU: Mali G31 MP2, support OpenGL3.2

3. RAM: 512MB/1GB DDR3L SDRAM

4. Display: HDMI2.0A interface, support 4K display

5. USB 2.0 port

6. 100M Ethernet + 100M WiFi

7. The same BTB header as the Raspberry Pi CM4
