BIGTREETECH SKR MINI E3 V2.0 32 Bit Control Board Integrated TMC2209 UART For Ender 3 - Refurbished
BIGTREETECH 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.
Features
- Use MP1584EN power chip, support 12-24V power input, the maximum output can reach 2.5A
- The hot bed MOS tube used WSK220N04, low on-resistance, larger head dissipation area, and reduce heat generation
- Onboard Sensorless homing function, which can be used by plugging in the jump cap
- Optimize the PCB board and frame to avoid the phenomenon of screw hole gap and screws hitting components
- Support BLtouch, filament detection, BTT UPS 24V V1.0, BTT Relay V1.2, etc.
- Onboard EEPROM: AT24C32
- Add parallel double Z-axie interface
- Increase the board layer: 4 layer board
- Increase the heat dissipation area of the back driver and strengthen the heat dissipation capacity
- Two CNC fan interfaces
- Increase the distance between the driving chip and the components to avoid the trouble caused by the heat sink
- Add protection device to the thermistor interface
- 5V power supply with BLtouch, TFT and RGB interfaces is optional
- The driver shares a physical UART port, which saves IO and enhances stability
