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 setup over Wi-FiDeveloper friendly REST API128-bit SSL encryptionWireless software updatesBreadboard compatiblePowered by the Spark CloudEasy Wi-Fi Set-Up ProcessSet-up steps:Enter your network name and password into the Spark App and press OK.That was it. Seriously. You¡¯re connected.The Spark Core makes first-time configuration of your devices a breeze for both creators and users. The Core includes a brand spankin new Wi-Fi module: the CC3000 from Texas Instruments. It features their unique setup process called Smart Config that allows makers and developers to bring their creations online in seconds.Reprogram the Core over Wi-FiThe Core is already Wi-Fi connected, so weve decided to do away with wires altogether.* You can program your new software in our web development environment or in your favorite text editor, and with a single click, Spark Flash delivers updated firmware to your project over the web.Spark Flash means that your projects stay in their enclosures, out in the field, and in the hands and homes of users, where they belong. It also means that your creations can be easily changed, updated, and improved over time, without worrying about USB ports and programmer pins.* Of course, you can still program the Core over USB or with a JTAG programmer, but wheres the fun in that?Technical Specifications32-bit STM32 72MHz ARM Cortex M3128KB of Flash memory, 20KB of RAMTexas Instruments SimpleLink CC3000 Wi-Fi chipEEPROM (supplied by the CC3000)2MB of external flash memory3.3V DC supply voltage (with on board power regulator)50mA typical current consumption300mA peak current consumption (during transmit events)Can be powered and programmed by USB Micro (cable included in box)8 digital I/O pins4 PWM pins8 analog I/O pinsUART (Serial), SPI, and I2C peripheralsWi-Fi range of 100-300ftResourcesSpark DevicesSpark Core: Wi-Fi for Everything (Arduino Compatible) on KickstarterSpark Core CommunityTutorialFor more product information and technical support, please contact hello@spark.io.Technical detailsDimensions 0mm x0mm x0mmWeight G.W 90gBattery Exclude
