Arcade game console is a programmable game console released by Microsoft. It can be developed through the makecode editor. The programming environment can be optionally modularized, so it is more suitable for educational use.

This game console is the first generation version and will continue to be improved. The following are the design contents of several main parts:

1. Power supply part: stm32f411ceu6 uses 3.3v power supply. The spx3819 voltage regulator chip is used here. Its main advantage is that it has fewer peripheral circuits and stable output. An ESD protector is added to the USB socket.

2. Microcontroller part: The crystal oscillator circuit uses a 24MHz SMD crystal oscillator. Other peripheral circuits can be viewed through the schematic diagram.

3. Charging circuit: Because the capacity of the lithium battery is not large, TP4056 is used here for charging. An independent microUSB interface is temporarily used here, and can be merged together later.

4. Others: The screen of the game console uses a 1.8-inch TFT screen, and the image direction can be modified through firmware. U8 is a reserved programming port, currently using a chip header. The test port mainly connects the test points of the power supply part.
