Overview
DVK511 is an expansion board designed for Raspberry Pi, integrates various components and interfaces for connecting external accessory boards. It's ideal for Raspberry Pi evaluation and development.

What's On Board

1. Pinheaders for connecting with the RPi
2. UART interface: easily connects to UART modules such as RS232, RS485, USB TO UART, etc.
3. 8I/Os interface: easily connects to modules controlled by I/Os, such as 8 Push Buttons
4. SPI interface: easily connects to SPI modules such as AT45DBXX Dataflash, etc.
5. I2C interface: easily connects to I2C modules such as PCF8574 Expansion Module, PCF8563 RTC Module, etc.
6. Character LCD interface: for connecting character LCDs like LCD1602
7. Graphic LCD interface: for connecting graphic LCDs like 2.2inch LCD or LCD12864
8. ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
9. RPi GPIO connectors
10. Power input/output
11. 5V DC jack
12. Power indicator
13. User LEDs
14. Potentiometer: for 2.2inch LCD backlight adjustment, or LCD12864, LCD1602 contrast adjustment
15. Power switch
16. Buzzer
17. Joystick: five positions
18. Infrared receiver
19. LCD selection jumper
    1. short the jumper for LCD12864
    2. open the jumper for 2.2inch LCD
20. ONE-WIRE jumper
21. Buzzer jumper
22. Infrared jumper
23. User LEDs jumper
24. Joystick jumper

For jumpers above:

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