BIGTREETECH SKR V1.4&SKR V1.4 Turbo motherboard is a 32-bit 3D printer motherboard optimized and upgraded by the 3D printing team of Shenzhen BigTree Technology CO., LTD. for the deficiencies of V1.3 version, especially for small and medium-sized printers.
BTT SKR V1.4 & SKR V1.4 Turbo Features
1. BTT SKR V1.4 with 32-bit main frequency 100MHz ARM level Cortex-M3 series LPC1768 main control chip, the performance has been greatly improved.
2. BTT SKR V1.4 Turbo with 32-bit main frequency 120MHz ARM level Cortex-M3 series LPC1769 main control chip, the performance has been greatly improved.
3. Equipped with highly modular and open source firmware Marlin2.0, which is convenient for users to DIY and secondary development.
4. Using dedicated power chip M6130, support 12-24V power input.
5. Support 2.4, 2.8, 3.5 inch color touch screen, support LCD2004 screen, LCD12864 screen.
6. Upgrade and configure the firmware through SD card, which is simple, convenient and efficient.
7. 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.
8. Support Resume Printing While Power Off, Filament Break Detection, Automatic Shutdown After Printing and so on.
9. High performance MOSFET tube, better heat dissipation effect.
10. Using removable fuse makes the replacement process easier.
11. Reserved extended port SERVOS and Probe to support BL Touch.
12. Support RGB light bar.
13. 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.
14. The special function interface uses the row needle with conspicuous color, which greatly reduces the error rate of wiring.
15. I2C, SPI and WIFI interfaces are reserved for convenience of DIY.
16. Closed-loop drive interface is reserved to reduce the trouble of plug-in switching module.
17. Double z-axis interface, eliminating the trouble of external drive expansion module.
18. The thermistor interface is protected by a bile capacitor pressurized resistor to enhance the resistance of the interface.
19. More fan interfaces: 1 way CNC fan, 3 way normally open fan.
20. Plug-in external DC5V power supply module to supply power to TFT screen, BL Touch and RGB.
