1. Onboard EEPROM: 24C322. 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 useOnboard sensorless homing function.Model: SKR MINI E3 V3.0Product name: SKR MINI E3 V3.0Board Layer: 4 layersPower input: DC 12/24VLogic voltage: 3.3VOnboard: TMC2209 motor driver UART modeMotor driver interface: , , , ZBM, Supporting display: TFT24, TFT35, 3 LCD12864 screen and other file formats G-codeCompatible: 3d printerNew condition: 100%Motor drive: onboard TMC2209 UART modeTemperature sensor interface: TH0, THB, 2-way 100K NTC (RTD)Colour:blackMaterial:ABSSize:10.375x7.25cmPackage Contents:1 x SKR MINI E3 V3.01 x screen cable
