DESCRIPTION:DVK512 is an expansion board designed for Raspberry Pi Model B+, integrates various components and interfaces for connecting external accessory boards. It's ideal for Raspberry Pi Model B+ evaluation and development.

Features: 

• Pinheaders for connecting with the RPi
• UART interface: easily connects to UART modules such as RS232, RS485, USB TO UART, etc.
• 8I/Os interface: easily connects to modules controlled by I/Os, such as 8 Push Buttons, Logic Level Converter, Mix Board, etc.
• SPI interface: easily connects to SPI modules such as AT45DBXX Dataflash, L3G4200D Board, etc.
• I2C interface: easily connects to I2C modules such as PCF8574 Expansion Board, PCF8563 RTC Board, LSM303DLHC Board, etc.
• Character LCD interface: for connecting character LCDs like LCD1602
• USB connector: USB TO UART, supported by onboard converter CP2102
• Power indicator
• User LEDs
• User Keys
• Potentiometer: for LCD1602 contrast adjustment
• RTC battery holder
• PCF8563: onboard RTC chip
• 32.768K crystal: RTC crystal
• CP2102: onboard USB TO UART chip, for debugging
• CP2102 jumper
• RTC jumper
• User LEDs jumper
• User Keys jumper

Note: 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
