[Lichuang Development Board]
 
Introduction to the NES game console expansion board based on the Liangshan School:
This is a game console expansion board based on the Lichuang development board, a handheld console that can run NES games.
 
The schematic design description
has been modified based on the Lichuang official game console expansion board.
①The joystick buttons were replaced, and the vibration module and lithium battery power supply interface were removed;
②The screen was changed to a 1.54-inch 240*240 SPI screen;
③The Tpye-c interface was used directly for power supply.
 
The PCB design instructions
place most components on the back, and the front looks particularly simple except for the joystick, buttons and screen.
 
Software description
① Since the official screen (resolution is 240*280) has been changed to 240*240 resolution, and the driver is the same, the official code can be displayed normally after making corresponding adjustments.
②The pin assignment of the joystick button has not changed, and the XY axis direction of the joystick has been adjusted.
