2. AMS1117-3.3: 3.3V voltage regulator
3. Power switch
4. Power indicator
5. LEDs: convenient for indicating I/O status and/or program running state
6. Reset button
7. User keys: for I/O input test and/or program control
8. Joystick: five positions
9. 12M crystal oscillator: enables the MCU run at 48M frequency by frequency multiplication
10. 8 I/Os interface | 8-channel AD interface
• for connecting accessory boards which using I/O control, such as 8 Push Buttons, Motor, etc.
• there's also 8-channel AD interface can be used for AD testing
11. SPI0 | SPI1 interface: for connecting SPI peripherals, such as DataFlash (AT45DBxx), SD card, MP3, etc.
12. I2C interface: for connecting I2C peripherals, such as I/O expander (PCF8574), EEPROM (AT24Cxx), etc.
13. 1-WIRE interface: for connecting 1-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
14. ISP | UART interface: for connecting ISP modules and/or UART peripherals, such as RS232, USB TO UART, etc.
15. LCD interface: for connecting 2.2 inch multi-color touch screen LCD which using SPI control
16. 5V DC jack
17. 5V/3.3V power input/output: usually used for power supply output, and/or common ground with other application board
18. MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion
19. SWD interface: for debugging/programming
20. LEDs jumper
21. User keys jumper
22. Joystick jumper

For jumper 20-22:

• short the jumper to connect to I/Os used in example code;
• open the jumper to connect to other custom pins via jumper wires.
