Digital design

In some Arduino applications, it is advantageous to be able to store and retrieve information locally. You can do this with a Secure Digital, or SD, card. An SD card is a non-volatile memory card used extensively in portable devices, such as mobile phones, digital cameras, GPS navigation devices, handheld consoles, and tablet computers. Another type of SD Card is the Micro SD card. Measuring only 15 mm x 11 mm x 1 mm, it is the smallest memory card available. It is about one-quarter the size of a normal-sized SD card, or about the size of a fingernail.

The new development board features a 32 MHz Quark and a host of features at a $14.95 price tag.

Sending phones into the sky may be the answer to bridging the gap between expensive drones and the amount customers are willing to pay for them.
