MIPS Creator Ci40 Development Board Powered by cXT200 SoC Launched for $53 on Kickstarter

Last year, Imagination Technologies launched their first community development board with MIPS Creator CI20 powered by Ingenic JZ4780 dual core MIPS processor running both Android and Linux, and now supported by various projects. The company has been teasing about its MIPS Creatort Ci40 for a few weeks, and was already announced as the MIPS platform of choice for Google Brillo operating system, but the board has now officially been launched via a Kickstarter campaign where you can get the board for $53, as well as some add-on boards. But instead of using a processor from one of their partner, Imagination just designed their own MIPS interAptiv SoC for the board. Creator Ci40 board specifications: SoC – Imagination Technologies Creator cXT200 with 2x MIPS interAptiv core @ 550MHz, 512KB L2 cache, and an Ensigma C4500 RPU (for 802.11ac/ BT 4.1 LE) System Memory – 256 MB DDR3 Storage – 512 MB […]

WigWag Simplifies Home Automation, Provides Raspberry Pi and Arduino Shields

WigWag is an home automation kit aiming at simplifying home automation, yet allowing developers to roll their own system via Arduino and Raspberry Pi Shields. Wigwag is currently composed of three devices: WigWag Sensor Block – Universal sensor device with 8 environmental sensors (light, detect motion, sound, temperature, humidity, movement…), 4 control features (relay, IR blaster…), and 2 expansion ports. It can be powered by 4x AA batteries (possibly for up to 1 year), or a USB power adapter. This device runs Contiki OS on Freescale MC1322 MCU (with built-in 6LoWPAN radio). WigWag Relay – Connects WigWag and third party devices to their cloud service, allowing interaction with Internet services, such as email, Dropbox and Twitter. It acts a bit like a central server managing all your WigWag Sensor Blocks or other connected devices such as Phillips Hue light bulbs or Belkin WeMo outlets in your house. IP networks (Wi-Fi & Ethernet) […]

Thingsquare Mist – Open Source Firmware for The Internet of Things

Thingsquare recently released the source code for the Thingsquare Mist firmware, an ultra lightweight router software (<4 kB memory) for the Internet of Things based on open Internet standards such as IPv6, RPL (Routing Protocol for Lossy networks), and 6lowpan. Thingsquare Mist allows to connect battery-powered wireless micro-controllers to the Internet, and is currently used in applications such as smart light bulbs, connected home appliances, and connected cities. The IPv6 mesh network is composted of nodes with a low power radio that communicate with the Mist router (Green), which in turn connect to the Internet and Thingsquare Cloud backend (Thingsquare Haven) to store the data, and/or receive control commands via Ethernet or Wi-Fi. The end users can then use an App to monitor, and/or control the devices remotely. Thingsquare Mist uses IETF RPL IPv6 mesh routing protocol (pronounced “ripple”) for IPv6 nodes communications. Thingsquare Mist runs on several low-power wireless […]
