BIGTREETECH SKR Mini E3 V3.0 Control Board Integrated TMC2209 UART Stepper Driver Supports Marlin/Klipper Compatible Ender 3/Ender 3 Pro/Ender V2 3D Printer Motherboard ZZB000590 Black

High-Performance STM Chip: The main Silent Control Board adopts STMicroelectronics latest G0 series MCU STM32G0B1RET6, ARM 32-bit Cortex-M0 CPU, new chip, bring you a different use experience, for Ender 3 , Ender 3 v2 , Ender 3 Pro , Ender 5 , CR10 3D printers. Practical and Beautiful Motherboard: The appearance of the Mainboard is very different from SKR Mini E3 V2.0 Control panel, which enhances the aesthetics of the Mainboards. It is a cool upgrade board. The USB interface is changed to USB Micro B, which is more versatile and easy to use. It has a longer service life than Mini USB, with up to 10,000 plug life and strength, improved performance, and smaller size. Fast Heat Dissipation: The design upgrade of the stepper motor driver heat sink increases the heat dissipation area and greatly improves the heat dissipation performance of the motherboard. The heat dissipation is faster, allowing the 3d printer motherboard to continue printing for a longer time. Silent Board: Increase the heat dissipation controllable fan of the whole machine, reduce the temperature of the whole machine when the device is working, and protect the board at every moment, so that the controller board has a longer service life. if you have problem that heating both bed and hot end not heat up, please contact us via Amazon. High Accuracy and Beautiful Printing: Increase SPI output port +3.3V power supply, external SPI sensor power supply voltage +3.3V and +5V are optional. You can extend use the more types of sensors, sensors can be provide higher accuracy and print quality to make your prints more beautiful. The SKR Mini E3 V2.0 board only has 5V power supply from the SPI output port. (The above 5 points are all upgraded based on the SKR Mini E3 V2.0 motherboard.)
