BIGTREETECH SKR Mini E3 V2.0 Control Board 32Bit Silent Motherboard For 3D Printer and TFT35 E3 V3.0.1 Display Touchscreen

• 【TFT35 E3 V3.0】 ARM Cortex-M3 series STM32F207VCT6 chip with 32-bit CPU 120MHz; Upgrade the firmware by SD card. It is easy and convenient to operate.
• 【SKR Mini E3 V2.0】 ARM Cortex-M3 Series STM32F103RCT6 Master Controller with 32-bit Main Frequency of 72MHz Chip;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.
• 【TFT35 E3 V3.0】 This display board has higher compatibility. Users can select two work modes:UART serial port screen mode and 12864 screen mode;Serial port screen mode supports two printing modes: SD card and U disk.
• 【TFT35 E3 V3.0】 LCD12864 mode uses EXP1, EXP2 and EXP3. EXP1 and EXP2 are LCD screen ports of normal motherboard. EXP3 is the LCD interface used by E3 series motherboard (such as SKR MINI E3 V1.2, SKR E3 DIP V1.1, etc)

If the board doesn't read from the sd card slot, the board or the screen doesn't work, please contact us, we will solve the problem for you immediately.TFT35 E3 V3.0 Product characters： 1）Use the light-emitting encoder, press the bright blue light, if not, it will not light, Full of technology； 2）TFT touch screen mode：serial port screen RS232 port； 3）2 sets of UART serial port extension ports are reserved for DIY use. SKR MINI E3 V2.0 Upgrade Features: Carries highly modular open source firmware Marlin 2.0, which facilitates user DIY and secondary development; Use MP1584EN power chip, support 12-24V power input, the maximum output current can reach 2.5A; The hot bed MOS tube uses WSK220N04, low on-resistance, larger heat dissipation area, and reduce heat generation; Onboard Sensorless homing function, which can be used by plugging in the jump cap; Optimize the plate and frame to avoid the phenomenon of screw hole gap and screws hitting components; Support BLtouch, filament detection, power-off resume, automatic shutdown, etc.; Onboard EEPROM: AT24C32; Add parallel double Z-axis interface; Increase the board layer to 4 layer board; And increase the heat dissipation area of the back driver and strengthen the heat dissipation capacity; Increase the distance between the driving chip and the components to avoid the trouble caused by the heat sink; The driver shares a physical UART port, which saves IO and enhances stability; Two CNC fan interfaces; And 5V power supply with BLtouch, TFT and RGB interfaces is optional; Note: Please contact us when you need firmware information or a manual.
