7.Joystick: five positions
8.Reset button
9.Crystal oscillator: 7.3728M & 32.768K
10. Adjustable resistor: for LCD12864 contrast adjustment
11.16 I/Os interface: for connecting accessory boards which using I/O control, such as FT245 USB FIFO, 8 SEG LED, etc.
12. 8 I/Os interface | 8-bit AD interface
        for connecting accessory boards which using I/O control, such as 8 Push Buttons, Motor, etc.
        there's also 8-bit AD interface can be used for AD testing
13.6 I/Os interface | USART0+AC+PWM3 interface
        for connecting USART peripherals, such as RS232, RS485, USB TO UART, etc.
        for connecting accessory boards which using PWM interface, also supports analog comparison through AC interface
14.SPI+PWM0+T/C interface
        for connecting SPI peripherals, such as DataFlash (AT45DBxx), SD card, MP3, etc.
        the SPI interface includes additional I/O pins (PWM, T/C as regular I/O) which can be used as controlling pins
        for connecting accessory boards which using PWM interface, also supports frequency calculation through T/C interface
15. I2C+PWM0/1 interface
        for connecting I2C peripherals, such as I/O expander (PCF8574), EEPROM (AT24Cxx), etc.
        the I2C interface includes additional I/O pins (PWM as regular I/O) which can be used as controlling pins
        for connecting accessory boards which using PWM interface
16.USART1 interface: for connecting USART peripherals, such as RS232, RS485, USB TO UART, etc.
17.1-WIRE interface: for connecting 1-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
18.PS/2 interface: for connecting PS/2 keyboard and/or mouse
19.Graphic multi-color LCD interface: for connecting 2.2 inch multi-color touch screen LCD which using SPI control
20.Graphic dot matrix LCD interface: for connecting dot matrix LCD, such as LCD12864 (3.3V blue backlight)
21.5V DC jack
22.Custom crystal socket
23.VCC power input/output: usually used for power supply output, and/or common ground with other application board
24.MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion
25. ISP6 interface: for programming
26.ISP10 interface: for programming
27. JTAG interface: for programming/debugging
28.LEDs jumper
29. User keys jumper
30.Joystick jumper
31. PS/2 jumper
32. LCD selection jumper
        short the jumper to use dot matrix LCD
        open the jumper to use multi-color LCD
33. VCC selection jumper
34.Crystal selection jumper


For jumper 28-31:
-  short the jumper to connect to I/Os that used in example code;
- open the jumper to connect to other custom pins via jumper wires.
