Features: Brand new and high quality This kit includes the BIGTREETECH SKR 3 control board and 4PCS TMC5160TPro motor driver, supporting speed printing. The BIGTREETECH SKR 3 powers adopts TPS5450-5A and supports DC12/24V powers input; The output current of the chip 5A, with value of 6A, perfectly supporting powers supply. The control fan of BIGTREETECH SKR 3 can achieve selection of 24V, 12V, and 5V through external powers module, saving customer the operationS of external module and reducing the motherboards damage. The BIGTREETECH TMC5160TPro motor driver adopts power and external powers MOSFET, which support larger current. The reach 8A (due to limited heating of the module, the cannot exceed 5A), and the heat during operations is low. The BIGTREETECH TMC5160TPro to stepping , allowing the motor to operate near its load, achieving a dynamic of 10times without any stepping.
