SD card logic voltage：3.3V and 5V（Similar to: assist MEGA2560 principal management chip motherboard, larger compatibility)
Notes
1. When utilizing 12864 display mode, join the port EXP1 and EXP2 to the motherboard. There isn’t any contact operate on this mode.
2. When utilizing serial port display mode, join with TFT or AUX-1 on the motherboard through RS232. This mode has contact operate；
3. Two work modes may be modified by one key. Press the encoder about 3 seconds till the mode choice web page seems, then press the encoder after choosing the mode.
1）ARM Cortex-M3 sequence STM32F207VCT6 chip with 32-bit CPU 120MHz; Improve the firmware by SD card. It’s simple and handy to function.
2）This show board has larger compatibility. Customers can choose two work modes:UART serial port display mode and 12864 display mode;Serial port display mode helps two printing modes: SD card and U disk.
3）Reserve WIFI port, and WIFI operate is realized by exterior WIFI module；Reserve the extension port of filament breaking detection (FIL-DET)；
4）Reserve the extension port of computerized shutdown after printing (PS-ON);
5）LCD12864 mode makes use of EXP1, EXP2 and EXP3. EXP1 and EXP2 are LCD display ports of regular motherboard. EXP3 is the LCD interface utilized by E3 sequence motherboard (equivalent to SKR MINI E3 V1.2, SKR E3 DIP V1.1, and so on.)
