About BIGTREETECH SKR 2 Control Board For 3D Printer New

Please Note: If you have any problem, you can write to me via Amazon, we have professional technical support staff to help you. Thank you for your support and cooperation. Motherboard features: 1. Uses a 32-bit ARM Cortex-M4 series STM32F407VGT6 main control chip with a core frequency of 168MHz that packs enough performance to run even the most demanding UI while ensuring stutter free printing. 2. Integrates a AOZ1284PI power regulator which supports 12-24V power input and a maximum output current of 4A – enough to power external components such as LEDs and even a raspberry pi; 3. Support all versions of the company's serial screen, SPI screen and LCD screen; 4. Upgrade the configuration firmware via SD card. This burning method is simple, convenient and efficient; 5. Supports functions such as power loss print resume, filament runout detection, shutdown after printing, BLtouch and other ABL sensors, RGB lights, etc. Note that external modules will be required for many of these functions; 6. Use high-performance MOSFET to reduce heat generation; 7. The use of replaceable fuses makes the replacement process more convenient; 8. Introduces a new “anti-reversal” stepper driver protection which is achieved through a combination of new hardware and Marlin firmware. This protects against motherboard or driver damage due to incorrect driver insertion; 9. ESP8266 WIFI module (ESP12S or ESP-07) interface for customers to use RRF firmware; 10. Onboard push-pull TF card slot (SDIO working mode) and U disk interface; 11. A filter circuit is added to the power input terminal to reduce ripple and noise interference; 12. The fuses now use a smaller package which leaves more space on the PCB for more features and makes it easier to swap them out; 13. The number of PWM controllable fan interfaces has been increased from one to three.
