Spark Core with Chip Antenna

Official announcement from Spark team:"During the summer we found the opportunities to further improve the manufacturability and RF performance of the Core. These changes have required more iterations on the board, more back-and-forth with the manufacturer, and more testing, pushing our milestones by a few weeks and meaning a small delay in shipping."You can check the up-to-date details on this website: https://www.sparkdevices.com/statusThe Spark Core is an Arduino-compatible, Wi-Fi enabled, cloud-powered development platform that makes creating internet-connected hardware a breeze. It is a tiny Wi-Fi development board, open source, widely successful funded Kickstarter project.This little board packs a punch: with a 72 MHz ARM Cortex M3, the best Wi-Fi module on the market, wireless programming, and lots of pin outs and peripherals, theres nothing you cant build with the Core.FeaturesArduino compatible (through custom integration of Wiring libraries)Open SourceWi-Fi 802.11 b/gEasy set
