SKR MINI E3 V3.0 is a motherboard tailored specifically for Ender3 printers, a perfect replacement for original Ender 3 printer motherboards. Increase SPI output port +3.3V power supply, external SPI sensor power supply voltage +3.3V and +5V optional. PC communication USB interface is changed from Mini USB to Micro USB B, which is more adaptable. Increase the power supply of the SPI output port, support the motherboard to directly supply power to the peripherals. Onboard TMC2209 mute driver UART mode, support mute printing. Increase the thermistor interface protection circuit to prevent burning of the main control chip.
