Semiconductor company Silicon Labs announced its new XPress series of development boards to facilitate creating connected devices. The XPress line, with Bluetooth and Wifi versions, promises to help developers focus on developing their product without having to spend time working on the code to drive wireless protocols.

The devices feature over-the-air updates and are driven by Silicon Labs’ Gecko operating system. Both can be monitored and configured via smartphone apps and can be monitored via USB cable on a PC. The wireless modules are also FCC pre-certified and can be seamlessly integrated into a custom PCB.

Development kits are available through major electronics supply houses for $29-40.

When the 2010 BP oil spill occurred, Keiana Cavé of New Orleans wondered whether hidden environmental damage might result. At 15, she began research to prove that theory and eventually discovered that when UV rays from the sun mixed with the oil on the ocean’s surface, the result was carcinogenic. Now a college junior, Keiana has published two research papers and holds two patents for methods of detecting toxins in ocean water. She aims to create a new dispersant to neutralize the cancer-causing chemicals. Her research received $1.2 million in funding from Chevron.
