Features: 48V High Speed Pressure: The motor voltage of SKR 3 EZ varies from 12V to 48V (for 48V the EZ5160 Pro driver must be used), while SKR 3 varies from DC12V to 24V.A high voltage can greatly improve your printing speed and has 3 normal fans, which can ensure the smooth operation of your printer and improve your print quality.Safe anti-misplugging designs: Incorrect driver installation not only causes damage to Driver themselves, but even ruins the mainboard or catches fire. Our newcomers SKR 3 EZ mainboard and series Driver with an unprecedented anti-misplug designs can completely eliminate such hidden dangers. Processor Updates:The new processor of the SKR 3 EZ Controller is upgraded to the 32bit 480MHz ARM CortexM7 series STM32H743VI, which increases the running speed and printing accuracy of the SKR 3 Controller during operation Its improved thermistor supports PT1000, eliminating the need for an external module. Supported LCD displays TFT35 /TFT28/12864 and stepper motor Driver EZ2209/EZ2208/EZ5160, TMC2209/TMC2208/TMC5150. Regarding firmware: The SKR 3 EZ Board is compatible three types of firmwares: supportMarlin, Klipper, andRepRap, and is widely used in the field of 3D printing.Note: Our control board comes without SDcard.
