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.

BIQU 3D Printer Part TFT 2.4 Inch Touch Screen Display RepRap Smart Controller Panel Similar 12864 LCD for Ender 3 SKR V1.3 MKS Gen Control Board (TFT 24 for Ender 3)

Product Description
TFT24 Touch Screen Youtube Video:
https://www.youtube.com/watch?v=TeRSGmcd8A8#action=share

Parameters
Appearance size: 105*46mm
Microprocessor: STM32F105RCT6
Input voltage: 5V

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:
BIGTREE_TFT24_12864_(version code).bin
BIGTREE_TFT24_Serial_(version code).bin

First copy the above firmware to SD root directory, and then insert the card into the SD card slot of the board
Next please re-power the board or press the reset key, and wait for about 10 seconds before the update is completed

Packing List
TFT 24 Screen *1 Cable *3(show as picture)

Product Features

  • Using 32bit frequency 72MHz ARM level Cortex-M3 series STM32F105RCT6 Microprocessor, the performance has been greatly improved
  • UART serial screen and 12864 screen two operating modes can be selected with more higher compatibility
  • Serial-screen mode supports both SD card and USB flash drive printing
  • Easy to operate with SD card to upgrade the Firmware

How to Use
The SKR motherboard connects with the computer via the [USB] interface. After the driver is installed, the motherboard can be inserted into the computer to recognize the port for data transmission. Without the driver installed, it is easy for the computer to not recognize the USB port

1. Smoothieware-usb-driver-v1.1 driver installation (Windows systems only) The driver can be obtained from our open-source network
Https://www.dropbox.com/s/ighnj7oa2l0bm5g/smoothieware-usb-driver-v1.1.exe?dl= 0
2. After installing the driver, connect the computer and SKR motherboard with USB cable
Note: When using smoothieware open-source firmware, since only Windows system drivers, the SKR board at this time can only be recognized by the Windows system port! ! !
3. If you are using Marlin2.0 firmware, follow the tutorial to install:
