Features: Brand new and high quality Using 32bit ARM series STM32H723VI main control chip, the performances has greatly improved. The power chip adopts TPS5450-5A, which supports DC12/24V power input. The output current of the chip is up to 5A, and the value can reach 6A, which perfectly supports the power supply of RPi. The motherboard reserves the BOOT button, users can update the motherboard boot program through DFU. Increase the protections circuit of the thermistor part to avoid the burning of main control chip due to leakage of the heated bed or heating rod. The numerical control fan realizes 24V, 12V, 5V voltage selection through the external power supply module, eliminating the need for the operation of the customer's external module, thereby reducing the probability of damage to the motherboard. The thermistor can select the pull-up resistance value through the jumpers, and support PT1000 in this way without the need for external modules, which is convenient for customers to use DIY. Supports functions such as resume printing, Filaments Runout Detection, Completed Shutdown, etc. Two types of CAN interfaces are reserved, USB port and XH2.54 6Pin terminal interfaces. The USB port is used to select CAN and USB through the double-poles double-throw switches, which is convenient for customers to use other accessories of the CAN interfaces.
