APF27 Dev

Description

The APF27_Dev board is a development platform: it is ideal for experimenting and testing simple embedded Linux applications.

It enables access to most of the APF27 board's functionalities while at the same time offering many additional features such as a touch screen controller, microphone input, audio, digital TV output,⁽¹⁾ CAN bus⁽¹⁾...

All the drivers necessary to use the board features are available in our Linux BSP.
