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;

Some Important Tips for TFT 24 Touch Screen
1,When using class 12864 screen mode, connect to the motherboard’s EXP1 and EXP2, in which No touch function
2. When using serial-screen mode, connect to TFT or AUX-2 on the motherboard via RS232. Touch function run in this mode
3,The two modes correspond to different firmware, please wire according to the pattern type of flashed firmware
4,There are two choice in the listing, if you select the “TFT 24 For Rnder 3”, we will send the extra cable which can connect with Ender 3 printer directly. Otherwise,it can’t connect without a special designed cable

How to update Firmware
1,Log in the open source website of our company to download: https://github.com/bigtreetech
2,Firmware file name:
