.BTT SKR MINI E3 V2.0 is a customized motherboard for Ender3 printer launched by the 3D printing team of Shenzhen BIGTREE technology co., LTD., which can perfectly replace the motherboard of the original Ender3 printer.
BTT SKR MINI E3 V2.0 Features

1. Use MP1584EN power chip,support 12-24V power input,the maximum output current can reach 2.5A

2. The hot bed MOS tube uses WSK220N04, low on-resistance, larger heat dissipation area, and reduce heat generation

3. Onboard Sensorless homing function, which can be used by plugging in the jump cap

4. Optimize the plate and frame to avoid the phenomenon of screw hole gap and screws hitting components

5. Support BLtouch, filament detection, power-off resume, automatic shutdown, etc .

6. Onboard EEPROM: AT24C32

7.  Add parallel double Z-axis interface

8.  Increase the board layer: 4 layer board

9. Increase the heat dissipation area of the back driver and strengthen the heat dissipation capacity

10. Two CNC fan interfaces

11. Increase the distance between the driving chip and the components to avoid the trouble caused by the heat sink

12. Add protection device to the thermistor interface

13.  5V power supply with BLtouch, TFT and RGB interfaces is optional

14. The driver shares a physical UART port, which saves IO and enhances stability
