The Raspberry Pi developer board has turned out to be a very popular device for DIY users. The Pi can be used for just about any project that the user can think up. Element 14 has announced that it has a new accessory for the Raspberry Pi available in the form of a new Wolfson audio card. The audio card is designed to be compatible with Pis that use the P5 pads. These pads are only found on the Revision 2 Raspberry Pi and later.
