[Lichuang Development Board] Game console expansion board based on Lichuang Liangshan School

## Schematic design description

The schematic diagram has been modified based on the Lichuang game expansion board. The main reason is that the power supply part is changed to use IP5306 for charge and discharge management. The circuit structure is simpler. You can directly refer to the manual to make some changes to the schematic diagram. , and IP5306 has its own power indicator. I used four 0603 packaged LEDs in this expansion board for power indicator. The original battery power ADC circuit in the circuit can be removed if there is no need to check the power on the display. ![Power Management.jpg]
The DS18B20 part was originally intended to display the current indoor temperature on the screen when the game console has no button operations for a long time. But I don’t have time recently, hey... I have to put it aside for now
