BIGTREETECH SKR Mini E3 V3.0 Motherboard

BIGTREETECH SKR Mini E3 V3.0 Motherboard

SKR MINI E3 V3.0 is a motherboard specifically designed for Ender 3 printers, serving as a perfect replacement for the 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, supporting the motherboard to directly supply power to the peripherals.
• Onboard TMC2209 mute driver UART mode, supporting silent printing.
• Increase the thermistor interface protection circuit to prevent burning of the main control chip.
