1. Adopt 32-bit main frequency 64MHz ARM Cortex-M0 series STM32G0B1VET6 main control chip;
2. 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;
3. The motherboard reserves the BOOT button, and users can update the motherboard boot program through DFU;
4. 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;
5. 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;
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 functions.
