Product Introduction
BTT SKR MINI E3 V1.2 motherboard is a ultra-quiet, low-power,
high-quality 3D printing machine control board. It is launched by the
3D printing team of Shenzhen BIGTREE technology co., LTD. This
board is specially tailored for Ender 3 printer, perfectly replacing the
original Ender3 printer motherboard.
Motherboard Features：
ARM Cortex-M3 series STM32F103RCT6 chip with 32-bit CPU 72MHz;
Equipped with highly modular open source firmware
Marlin2.0 ,convenient for users DIY and secondary development, exempt from
the worries of the core code;
Using powerful development tools, Visual Studio Code integrated
development environment: support online debugging, more helpful
for product development and performance optimization, using C
language development, low development threshold;
PCB board wiring is rigorous and beautiful, and specializing in
heat dissipation optimization;
Using a dedicated power chip to support 12-24V power input;
Accept 24V input, reduce the hot bed current to 1/4 at the same
power,effectively solve the hot bed MOS tube heating problem;
Support 2.8-inch, 3.5-inch color touch screen and original Ender3 printer
LCD12864 screen;
Upgrade the firmware by SD card, it is easy and convenient to operate;
Use firmware to set the driving current mode, avoid manual
adjustment of current and cause burnout drive.It
’
s convenient,
safe and reliable;
Support functions such as Neopixel lights, printing after power failure,
broken material detection, and power off after ending;
The motherboard integrates the UART mode of TMC2209, making the debugging
of motherboard and driver become simple and integrated.
The motherboard reserves the extension port of part of TMC2209 pins for the
convenience of users to use DIAG instead of Endstop and some other functions.
