$25 Orange Pi Lite2 Board Comes with Allwinner H6 Processor, 802.11ac WiFi + BLE Module, USB 3.0, and More

After Shenzhen Xunlong launched of the first low cost Allwinner H6 development board with Orange Pi One Plus at the very end of last month, we know more Allwinner H6 were coming, and the company has now launched Orange Pi Lite2 development board with 1GB LPDDR3, 802.11ac WiFi and Bluetooth module, and a USB 3.0 port. The board however does not come with an Ethernet port, so people wanting to get H6 with Gigabit Etheret and USB 3.0 will need to wait a little longer. Orange Pi Lite2 is sold for $25 plus shipping on Aliexpress. Orange Pi Lite2 board specifications: SoC – Allwinner H6 V200 quad core Cortex A53 processor with Arm Mali-T720MP2 GPU System Memory – 1 GB LPDDR3 Storage – micro SD card slot up to 32GB Video Output – HDMI 2.0a up to 4K @ 60 Hz with HDCP 2.2 (TBC) Audio – HDMI audio output, […]

Top Programming Languages & Operating Systems for the Internet of Things

The Eclipse foundation has recently done its IoT Developer Survey answered by 713 developers, where they asked IoT programming languages, cloud platforms, IoT operating systems, messaging protocols (MQTT, HTTP), IoT hardware architectures and more. The results have now been published. So let’s have a look at some of the slides, especially with regards to programming languages and operating systems bearing in mind that IoT is a general terms that may apply to sensors, gateways and the cloud, so the survey correctly separated languages for different segments of the IoT ecosystem. C and C++ are still the preferred languages for constrained devices, and developers are normally using more than one language as the total is well over 100%. IoT gateways are more powerful and resourceful (memory/storage) hardware, so it’s no surprise higher level languages like Java and Python join C and C++, with Java being the most used language with 40.8% […]

FOSDEM 2017 Open Source Meeting Schedule

FOSDEM (Free and Open Source Software Developers’ European Meeting) is a 2-day free event for software developers to meet, share ideas and collaborate that happens on the first week-end of February, meaning it will take place on February 4 & 5, 2017 this year. FOSDEM 2017 will features 608 speakers, 653 events, and 54 tracks, with 6 main tracks namely: Architectures, Building, Cloud, Documentation, Miscellaneous, and Security & Encryption. I won’t be there, but it’s always interesting to look at the schedule, and I made my own virtual schedule focusing especially on talks from “Embedded, mobile and automotive” and “Internet of Things” devrooms. Saturday 4, 2017 11:00 – 11:25 – Does your coffee machine speaks Bocce; Teach your IoT thing to speak Modbus and it will not stop talking, by Yaacov Zamir There are many IoT dashboards out on the web, most will require network connection to a server far […]

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 […]
