$15 Open Source Hardware VoCore Wi-Fi Module Runs OpenWRT (Crowdfunding)

There are already low cost Wi-Fi modules that can be used for the Internet of Things such as AsiaRF AWM002 and Hi-Link HLK-RM04. However, AsiaRF mainly caters to companies, and the Hi-Link module has a limited memory (16MB), which may or may not be an issue depending on your application. VoCore Wi-Fi module could prove to be an interesting option as it is the same $15 to $20 price range, runs OpenWRT with 32 MB RAM, will be open source hardware, and provides up to 20 GPIOs in a tiny (25x25mm) form factor. VoCore Wi-Fi module specifications: SoC – Ralink/Mediatek RT5350 MIPS processor @ 360MHz with dual band 802.11n Wi-Fi with data Rate up to 150Mbps System Memory – 32 MB RAM Storage – 8MB SPI Flash (for firmware) / 16 MB on limited edition Available Signals (Via through holes): 10/100M Ethernet USB UART, I2C, SPI I2S, PCM JTAG Over 20 […]

$15 AsiaRF AWM002 & AWM003 Wi-Fi Modules Run OpenWRT, Expose GPIOs

This week-end I explained how to build a web server that could be used for automation and other Internet of things applications for less than $15 by combining an Arduino Leonardo with ECN18J60 Ethernet module. The hardware itself is cheap, but it may not always be convenient, or cost effective, to wire your house or office with Ethernet cables. One solution is to use Wi-Fi modules such as TI CC3000 evaluation module, an Electric Imp module, or Ariettea G25 + Wi-Fi board, but these usually cost between $30 to $50 in single quantity. AsiaRF AWM002 and AWM003 are low cost 802.11n Wi-Fi modules with access to GPIOs that could be an interesting alternative as they cost $15 + shipping, and even below $10 in quantities. The only difference between the two is that AWM003 supports more RAM (64MB vs 32MB). Here are the specifications for these modules: SoC – Mediatek/Ralink […]

ARM TechCon 2013 Schedule – ARM Servers, Internet of Things, Multicore, Hardware and Software Optimization and More

ARM Technology Conference (TechCon) 2013 will take place on October 29 – 31, 2013, in Santa Clara, and the detailed schedule for the event has just been made available. In the previous years, the conference was divided into  Chip Designs day (1 day), and the other 2 days were reserved for Software & System Design, but this year it does not appear to be the case. Whether you’ll be able to attend the event or not, it’s worth having a look at what will be discussed there in order to have a better understanding of what will be the key ARM developments in the near future in terms of hardware and software. There will be around 90 sessions categorized into 15 tracks: Accelerating Hardware Development – This track explores the resources, tools, and techniques that designers can employ to quickly bring hardware to market. Topics include multicore design, ARM IP, […]

BiKN Technology Platform: 802.15.4 Wireless Sensor Network

NXP and Treehouse Labs has unveiled BiKN technology platform that uses low-power 802.15.4 wireless chip technology from NXP Semiconductors to enable the “Internet of Things”  and opens new markets and applications for affordable wireless sensor and control networks. This technology allows to track “Smart Objects” tagged by wireless sensors and monitor (and possibly control) them via an application running on mobile devices, PC or Cloud servers. BiKN Technology Platform can be used in a range of applications including home and industrial automation, smart energy management, improving tracking and monitoring of equipment and inventory in retailing and hospitality, enhancing safety monitoring and security in healthcare, social services, athletics and educational environments. BiKN Technology Platform works by integrating hardware and software, operating through mobile and web-enabled devices, and leveraging IEEE802.15.4 low-power networking standards. Treehouse Labs uses the NXP JN5148 ultra low-power wireless microcontroller and the JenNet-IP open source wireless network protocol stack […]
