1. 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.
1.1 Main Features
1.1.1 CB1
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
1.1.2 M4P
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
