1. Onboard EEPROM: 24C32 2. Double Z-axis interface: add parallel double Z-axis interface. 3. The operation is more stable. 4. Compatible with 3, 3 Pro, 5, -10, etc. 5. Better protection and safety design: Increase the distance between the driver chip and the components to avoid the trouble caused by the heat sink. 6. Support more function expansion: BLTOUCH, filament detection, power failure recovery, automatic shutdown (PS-ON), etc. 7. Add 5V power supply, with BLTOUCH, TFT and RGB interfaces. 8. Better heat dissipation performance: larger heat dissipation area and better heat dissipation effect. 9. Three CNC fan interfaces: Change the commonly used interface to CNC fans, which is convenient for users to use Onboard sensorless homing function.
