Item Type: 3D Printer Control Board Material: PCB Opening Size: Approx. 102 x 76mm / 4.02 x 2.99in External Size: Approx. 110 x 84mm / 4.33 x 3.31in Processor: STM32 Input Voltage: 12V to 24V 5A to 15A Stepper Driver: 4988, 8825, 8729, 2100, 2208... Temperature Sensor Interface: NTC100K, 31855 TFT Screen: 3.5 (inch) Print File Format: G code Supported Machine Build: for XYZ, for delta, for kossel, for corexy Recommended Software: for Cura, for Simplify3d, for Pronterface, for Prpetier Host Firmware Upgrade: Storage card 1、Excellent Sensitivity: The 3D printer control board uses a 32 bit high speed ARM chip and the self developed main board. 2、Remote Printing: The 3D printer mainboard controller can be easily upgraded with firmware via storage card, with high speed WiFi module, access to the cloud to achieve remote printing. It supports setting the stepper drive current in the config file, so you no longer have to worry about adjusting the current to burn the mainboard. 3、Multifunction: You can design your own boot logo and all buttons, at least 15 command buttons can be customised, you can design your own boot logo and all buttons. Support for breakpoints, power saving, power failure detection, automatic shutdown, etc. 4、Efficient Heat Dissipation: This 3D printer control board uses MOSFET for better heat dissipation, 12 to 24V power input, reducing the heating bed current by 1/4, effectively solving the Mosfet heating problem. 5、Main Usage: The 3D printer mainboard controller is plug and play on for Ender series printers with the BTT SKR MINI E3 V3.0 control board. 1 x 3D Printer Control Board 1 x USB Blue Cable 1 x TFT35 3.5 Inch Touch Screen 1 x Touch Screen Cable
