10. In CNC fan ports: FAN0, FAN1, and FAN2, a 24V (DCIN) or 5V power supply can
be selected with a jumper cap (Note: the voltage of the three CNC fans should be
the same, and cannot be set to different voltages individually)
11. MCU firmware can be upgraded through SD card, or through DFU with Klipper's
make flash command
12. On-board TMC-driven SPI and UART working modes, on-board DIAG function
pins, can be used by simply plugging and unplugging the jumper cap
13. Support filament runout detection, BLTouch, RGB lights...
14. Adopt replaceable fuse for easy replacement
