DVK521 Cubieboard1/2 Baseboard Available Now November 30, 2013
Overview
DVK521 is an expansion board designed for Cubieboard, integrates various components and interfaces for connecting external accessory boards. It’s ideal for Cubieboard evaluation and development.
- Cubieboard socket
- OV7670 interface: for connecting OV7670 Camera Module
- 8I/Os interface: easily connects to modules controlled by I/Os, such as 8 Push Buttons
- SPI interface: easily connects to SPI modules such as AT45DBXX Dataflash, etc.
- I2C interface: easily connects to I2C modules such as PCF8574 Expansion Module, PCF8563 RTC Module, etc.
- USB interface: USB TO UART, convenient for debugging
- VGA interface: for connecting VGA display Module
- Capacitive touch screen socket: for connecting capacitive touch screen using I2C interface
- 7inch LCD interface: for connecting 7inch LCD
- ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
- UART interface (PL2303TA): connects to the UART interface of Cubieboard
- Cubieboard Ext Ports
- 5V/3.3 V power input/output: usually used as power output, also common-grounding with other user board
- Power indicator
- User LEDs
- Buzzer
- User Keys
- Joystick: five positions
- PL2303TA: onboard USB TO UART convertor
- 12M crystal: for PL2303TA
