BIGTREETECH Manta M4P Control Board Running Klipper with CB1/CM4

Brief Introduction

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

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. In CNC fan ports: FAN0, FAN1, and FAN2, a 24V (DCIN) or 5V power supply can be selected with a jumper cap (Note: the voltage of the three CNC fans should be the same, and cannot be set to different voltages individually).
11. MCU firmware can be upgraded through SD card, or through DFU with Klipper’s make flash command.
12. 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.
13. Support filament runout detection, BLTouch, RGB lights.
14. Adopt replaceable fuse for easy replacement.
