1. The SOC uses Rockchip's 4-core -A53 architecture RK3328 with Armbian system to perfectly run the Klipper host. 2. MCU uses STM32F407VET6 with - architecture, 168Mhz main frequency, easy to control machine actions 3. Retain the rich interface resources of MKS PIE with 1 Gbytes of DR3 memory, support screen interface, PI-TS35 screen interface, provide wired Ethernet port, 3-way USB interface (can be connected to external main control board, USB wireless network card, USB camera , U disk, USB keyboard and mouse) 4. Support booting the system from TF card and EMMC module (EMMC module is more stable than TF card, and the reading and writing speed is also faster), and provide supporting EMMC burning tools 5. Support 7-axis stepping drive, which meets the requirements of most 3D printer models. 6.3 MP1584 PEN DC/DC modules provide a strong for the stable operation of the entire board circuit. 7. 3 channels of controllable fans, plus 3 channels of normally open output, can independently choose VIN, 1V or 5V voltage. 8. Design Schottky diode protection for MOS circuits and temperature measurement circuits 9. Design the back EMF energy absorbing circuit to protect the stepping drive module 10. The Z+ interface can independently set the voltage selection to adapt to different types of PROBE.
