BTT SKR MINI E3 V2.0 HD

SKR MINI E3 V2.0 was designed by BIGTREETECH. We are committed to easy printing, easy life. SKR MINI E3 V2.0 upgrade on the base of SKR MINI E3 V1.2. It is capable with ender3, ender3 pro, ender5 and CR-10. Basic Parameters: Size:100.75 * 70.25mm MCU: ARM Cortex-M3 STM32F103RCT6 Power input: DC 12 / 24V Logic voltage: 3.3V Motor drive interface: XM, YM, ZAM, ZBM, EM Temperature sensor interface: TH0, THB, 2 channels 100K NTC (thermal resistance) Screens:BTT TFT24, TFT35 V2.0, TFT35 V3.0, TFT35 E3 V3.0, LCD12464,etc. Characteristic: ① The TMC2209 driver use same physical UART port, which save IO and increase the stability of motor drivers. ② We increase an double Z-axis interface on the motherboard which can work on printer with single or double Z-axis. ③ We set a EEPROM( AT24C32) on the board , so data storage is more stable. ④ Printed circuit boards of SKR MINI E3 V2.0 have 4 layers, which prolong the life of this board. ⑤ Power chip is MP1584EN and increase the current output which can reach to 2.5A. ⑥ We add protective device to interface of thermistor. ⑦ We also set two numerical control fan and a interface (PS-ON) for automatic shutdown after printing. ⑧ MOSFET of heated bed is WSK220N04, which increase heat dissipation area and reduce the heat release. ⑨ The distance between drive chip and other parts was enlarged to avoid malfunction of motherboard caused by heat sink. ⑩ The heat dissipation area on the back of the drive was broadened to improve heat dissipation capacity. ⑪ SKR MINI E3 V2.0 has sensorless homing function, just plug jumper cap in and it will work. ⑫ We optimize the frame of board, which avoid screw hole stripping and the screw collide other parts. ⑬ BL touch, TFT and RGB have 5V independent power interface. ⑭ SKR MINI E3 V2.0 also supports BL touch, filament run-out sensor, power-off resumed printing, and automatic shutdown after printing.
