BIGTREETECH SKR Pro v1.2 32-bit Motherboard high-Frequency 3D Printer Control Board

BIGTREETECH SKR Pro BIGTREETECH SKR V1 .4 motherboard is a 32 bit 3D printer motherboard optimized and upgraded by the 3D printing team of S henzhen Big Tree Technology CO ., LTD . for the deficiencies of V1.3 version, especially suitable for small and medium sized printers.

SKR Motherboard Features BIGTREETECH SKR Pro:
1）Using 32 bit main frequency 100MHz ARM level Cortex M3 series LPC1768 main control chip, the performance has been greatly improved;
2）Equipped with highly modular and open source firmware Marlin2.0 , which is convenient for users to DIY and secondar y development
3）Using dedicated power chip M6130, support 12 24V power input
4）Support 2.4, 2.8, 3.5 inch color touch screen, support LCD2004 screen, LCD12864 screen
5）Upgrade and configure the firmware through SD card, which is simple, convenient and effici ent
6）The SPI and UART working mode driven by the TMC driver, also having the DIAG pin, which eliminates complex wiring process and can be used           by simple unplugging jumper cap;
7）Support Resume Printing While Power Off , Filament Break Detection, Automatic Shutdown After Printing and so on
8）High performance MOSFET tube, better heat dissipation effect;
9）Using removable fuse makes the replacement process easier;
10)   Reserved extended port SERVOS and Probe to support BL Touch;
11）Support RGB light bar
12）Use the power selection design to separate the USB power supply from the switch power supply, effectively avoiding the situation that the USB              port of the computer is burnt out due to short circuit;
13）The special function interface uses the row needle with conspicuous color, which greatly reduces the error rate of wiring.
14）I2C, SPI and WIFI interfaces are reserved for convenience of DIY;
15）Closed loop drive interface is reserved to reduce the trouble of plug in switching module
16）Double z axis interface, eliminating the trouble of external drive expansion module;
17）T he thermistor interface is protected by a bile capacitor pressurized resistor to enhance the resistance of the interface
18）More fan interfaces: 1 way CNC fan, 3 way normally open fan

19）Plug in external DC5V power supply module to supply power to TFT screen, BLtouch and Neopixel
