BIGTREETECH SKR Mini E3 V1.2 Control Board 32Bit with TMC2209 UART Driver 3D Printer Parts Cheetah for Creality Ender 3

Features:

Carries highly modular open source firmware Marlin 2.0, which facilitates user DIY and secondary development;

PCB board wiring is rigorous and beautiful, and has been specially optimized for heat dissipation.

Special power chip is used to support 12-24V power input.

Acceptable 24V input, the same power can reduce the hot bed current to 1/4, effectively solve the hot bed.MOS tube heating problem;

Upgrading firmware by SD card makes operation simple and convenient.

Firmware is used to set the driving current so as to avoid burning out the driving caused by manual regulation of the current.Convenient, safe and reliable;

Product Features

  • 1)ARM Cortex-M3 Series STM32F103RCT6 Master Controller with 32-bit Main Frequency of 72MHz Chip;
  • 2) Supporting display :2.8 inch, 3.5 inch color touch screen and Ender3 printer LCD12864 screen;
  • 3)Support BLtouch, RGB color lamp, block detection, shutdown and other functions;
  • 4) Integrate UART mode of TMC2209 to simplify debugging of motherboard and driver.Reserve expansion ports for TMC2209 pins to facilitate users to use DIAG instead of Endstop.

Chip upgrade Using the latest high-quality chips, higher compatibility and better conductivity.(It is believed that only high quality products can ensure the quality of your work and bring safety to your work.)

Product Features

  • Compared with ordinary A4988, our high quality A4988 drive production process is improved again by PCB gold plate process (gold-plated pin) SMT placement machine manufacturing, non-manual welding, higher yield and more stable performance.
  • Performance upgrade: PCB covering copper process upgrade to 2oz (our high-quality copper thickness 70um, ordinary 35um), higher copper content, better heat dissipation performance.
  • Under 2A current, it can work for a long time. It is very suitable for 3D Printer, Mendel, Huxley and other machines.
  • Using the latest chips, higher compatibility and better conductivity
  • Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage toachieve higher step rates.
