1. Adopt 32-bit main frequency 64MHz ARM Cortex-M0 series STM32G0B1VET6 main control chip; The power supply chip adopts TPS5450-5A, which supports DC12/24V power input. The output current of the chip is up to 5A, and the peak value is up to 6A, which perfectly supports the power supply of Raspberry Pi;2. The motherboard reserves the BOOT button, and users can update the motherboard boot program through DFU;3. The 24V, 12V, and 5V voltages of the CNC fans are optional, eliminating the need for the customer to operate an external transformer module, thereby reducing the chance of damage to the motherboard;4. The thermistor can select the pull-up resistance value through the jumper, in this way, it supports PT1000 without external module, which is convenient for customers to use DIY; MCU firmware can be upgraded through SD card, or MCU firmware can be updated through DFU through Klipper's make flash command;5. The main board and the core board use the BTB connection method, so that other core board solutions other than CM4 can be selected; Support material break detection, shutdown, BLTouch, RGB lights and other functions1. DSI1, CSI1 interface (for CM4)2. Gigabit Ethernet interface (1000M for CM4, 100M for CB1)3. 3 USB 2.0 ports4. Equipping the ESD protection chip on the USB and Ethernet ports to prevent beingbroken down by the static electricity5. When working with Raspberry Pi CM4, its 40pin pin header has the same functionas that of Raspberry Pi(Custom IO for CB1)6. Using a BTB board-to-board connection, which can be further reinforced withscrews, perfectly compatible with CB1 or Raspberry Pi CM47. The MCU adopts STM32G0B0RE 32-bit ARM Cortex-M0+ @64MHz chip8. The power chip adopts TPS5450-5A, which supports DC12/24V power input, theoutput current of the chip is up to 5A, and the peak value can reach 6A, which perfectly supports the power supply of the core boardType: M8Psize:170 x 102.7mmMaterial: plasticcolour: blackPackage Contents:1 x Manta MotherboardOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
