STM32Boy game console

Purpose of the Stm32boy game console based on the STM32G03xFx series.
    I accidentally discovered the arduboy game console, which is very mini, so I came up with the idea of ​​transplanting the STM32.
 
Hardware design
    MCU circuit
    MCU adopts STM32G030F6, 64KHz, 32KFlash, 8KRam, TSSOP20 package (can be upgraded to STM32G031F8, 64KFlash).
   The main control of the arduboy game console is atmega32u4 (16KHz, 32KFlash, 2.5KRam, 1Keeprom). It uses an SPI screen, several buttons and a buzzer. The STM32G030F6 hardware should meet the transplantation conditions.
    The power supply circuit
    uses TP4057 battery management chip and XC6206 regulated 3.3V power supply.
    The key
    direction keys use commonly used 6*6 buttons, and 5-dimensional buttons can also be used. Two pads are configured on the board at the same time.
    The display
    supports a monochrome 128*64 SPI interface screen. The pin method is compatible with the SPI interface of Zhongjingyuan OLED. The maximum available screen is 1.3 inches. The FPC interface is compatible with the 1.4-inch screen of Aubao Laowang (10pin, 0.8 pitch, available on hand). ), I don’t like to modify it myself.
    CS optional welding R6/R7 (0Ω) can be optionally grounded or connected to PA4 (hardware NSS can be used).
 
The software design
 
    is in progress.

Update:
V1.1
1. For a beautiful appearance, the switch and USB port are moved under the board
2. To be compatible with the general OLED interface, the Zhongjingyuan OLED is used SPI interface sorting.
3. Adjust the position of some components to make welding easier.
4. Add some logos.
