Category: 3D Printer Display and Controller

This is a BIGTREETECH BTT SKR V1.4 Turbo Control Board for 3D Printer . Using the 32 bit main frequency 100 MHz arm level cortex M3-series, LPC1768 main control chip the performance has improved. It is equipped with highly modular and open source firmware marlin 2.0 which is very convenient for users. The controller board is responsible for the electronic functioning of a 3D printer.

Without a controller board, a 3D printer wouldn’t really be able to do anything except turn certain components on and off at the manual flick of a switch. 3D printer controller boards handle all the logic, such as parsing g-code files, regulating temperature, and moving motors. The last action is particularly computationally and electrically substantial since we’re talking about stepper motors. First of all, this BIGTREETECH SKR V1.4 Turbo Control Board is a 32-bit board — compared to something like the RAMPS or RAMBo, which are 8-bit boards. But the power gains don’t stop there because this 3D printer controller board boasts a 120-MHz processor, which is leaps ahead of the older ATMega chips that only clock 8 MHz.


1) Adopt high-performance MOSFET tube, better heat dissipation effect;
2) The use of pluggable fuses makes the replacement process easier;
3) Reserve BLTouch interface SERVOS and Probe for easy use of BL Touch;
4) RGB light bar supporting Neopixel scheme;
5) Use the power selection design to separate the USB power supply from the switching power supply, effectively avoiding short circuit Causes the computer’s USB port to be burned;
6) The special function interface uses conspicuous pin headers, which greatly reduces the error rate of wiring.
7) Reserved I2C, SPI, WIFI interfaces, convenient for customers to DIY
