Geeetech Spark E3 3D Printer Motherboard Support Klipper/Marlin Compatible TMC2209 TMC2208 A4988 Pluggable Driver Modules Design 32Bit Silent Motherboard for Ender3/Ender Pro/Ender3 V2/Ender5/Ender6

【Main Chip of Control Board】The main control chip of the 3D printer control ler adopts ARM Cortex M3 32-bit STM32F103RCT6 which has a lot of resources in the open source community. The main frequency is up to 72MHz.
【Pluggable Driver Modules Design】Geeetech’s 3D printer silent board has 4 stepper motor drivers which are designed with pluggable modules. Support TMC2209, TMC2208 and A4988 stepper driver. Support TMC2209 sensorless function. Compared with the onboard motor drivers, users can chose the drivers by themselves.
【Durable Design】The hot bed and hot end adopt ultra-high current MOS tube, which is more durable and not easy to damage. The 24V, 5V, and 3.3V power supplies all use large-capacity filter capacitors, which can provide better stability and user experience for 3D printers. It can be used to upgrade the original motherboard for Ender3/Ender Pro/Ender3 V2/Ender5/Ender6 and other models.
【4 CNC Fan】The 3d printer control board has 4-way fan interface, 3-way PWM control, one normally-open-fan interface.
【More Functions】The main board supports functional extension modules such as bl touch, neopixel light strip, filaments breakage detetion, resume power off, support 8080 interface screen, Ender 3 original 12864 LCD, serial port screen
