BIGTREETECH SKR Mini E3 V3.0 Control Board with TMC2209 UART Stepper Driver New Upgrade 32Bit 3D Printer Silent Board for Ender-3, Ender3 Pro, Ender-3 V2 3D Printer
【Main Control Chip】Adopt STMicroelectronics' latest G0 series main control chip STM32G0B1RET6 or STM32G0B0RET6; Add thermistor interface protection circuit to prevent damage to the main control chip.
【Three CNC Fan】Increase the heat dissipation controllable fan to reduce the printer temperature when the device is working; The fan port needs to ensure that the fan voltage specifications are consistent with the motherboard power supply, otherwise the fan will have no voltage.
【Heating Output】Support heating hot end and hot bed output. The heating indicator light will light up when the heating hot end or hot bed is correctly connected and powered on. Please connect the wires in a power-off state, otherwise it may cause static breakdown of the MOSFET and damage to the control board.
【Heat Sink Upgrade】Redesign the drive heat sink, strengthen the drive heat dissipation capacity, and greatly improve the heat dissipation performance; There are 4 tmc2209 silent drivers onboard the motherboard.
