Fun and scalable geek handheld
The core configuration
1. STM32F030CCT6 MCU, with 256K FLASH, enough space
2. 0.96 inch OLED screen, SPI interface.
3. MICRO SD card, SPI interface
4. CH340E USB to serial chip, easy debugging
5. 24C04 EEPROM, key data storage
6. Lithium battery management, automatically switch power
7. Audio power amplifier chip with simple mixing circuit
8. Reserve extra IO and communication interface for easy expansion
Based on the above hardware,
we can DIY a lot of interesting things,
for example as follows
1. Game console, not much to say about this
2. Smart car control panel
3. Internet of Things Control Panel
4. More ways to play, to be discovered
