 ==== About ==== ==== About ====
 +DVK521 is an expansion board designed for Cubieboard by Waveshare Electronics(a Chinese company), integrates various components and interfaces for connecting external accessory boards. It's ideal for Cubieboard evaluation and development.
  
-George Ioakimedes of IO Technologies,​ LLC (a USA based company) is announcing the availability of their Baseboard for CubieboardThis is a very important addition to the Cubieboard community. +{{..:​DVK521-intro.jpg}} 
- + 
-As George explains it“A Baseboard is a developer board and, like the Cubieboard, is very extensible and can connect to a variety of devices including sensors. To simplify the connection to additional devices, it is common to have an additional printed circuit called daughterboard or baseboard. This board is a baseboard, because it acts as a base to the Cubieboard. The Cubieboard can take power from this baseboard.” +
