WifiDuino Arduino Compatible Wi-Fi Board Features an Optional OLED Display (Crowdfunding)

Getting Wi-Fi with Arduino can be relatively expensive, and may take a little too much space. Spark Core board greatly addressed both price ($39) and form factor issue last, but there’s another option coming to market thanks to WifiDuino a $34 board with Wi-Fi, that’s tiny and Arduino compatible. An OLED display is also available as an option, at a lower price point than MicroView board, and including Wi-Fi or not, depending on the perk. WifiDuino hardware specifications: MCU – Atmel Atmega32U4 (same as Arduino Leonardo) Display – Optional 128×64 OLED display Connectivity – Optional Wi-Fi 802.11 b/g with STA, AP and ADHOC network modes Digital I/Os – 20 Analog I/Os – 12 Other I/Os – 7x PWM, UART, I2C, SPI Power – 5V Dimensions – Duino board only without Wi-Fi nor OLED: 25.6mm x 38.8mm x 11.0mm WifiDuino support the Arduino IDE, so you can write you sketch as […]

AsiaRF AWM002 Wi-Fi Module and a Tiny IoT Server Kit Get Crowdfunded for $15 and Up

VoCore Wi-Fi module selling for $15 to $20, and it’s corresponding VoCore Dock with Ethernet has been quite popular, and at the time of writing, the project has already received $40,000 in funding with 50 more days to go. But if you’d rather get something for the same price, a few months early, and an already FCC/CE certified and proven module and tiny IoT server, AsiaRF has also launched a crowdfunding campaign for their AWM002 Wi-Fi module running OpenWRT on the same Ralink RT5350 found on the VoCore. as well as AWM002 Tiny Kit which adds Ethernet and USB, and a larger board with easier access to all ports and I/Os. As a reminder, let’s go through AWM002 specifications again: SoC – Mediatek/Ralink RT5350 MIPS 74KEc core @ 360 MHz dual band 802.11n Wi-Fi with data Rate up to 150Mbps, hardware NAT, QoS, TCP/UDP/IP checksum offloading. System Memory – 32 MB Storage […]

$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 […]

DLink Introduces DSP-W215 Wi-Fi Smart Plug for iOS and Android

D-Link is entering the automation market with a Wi-Fi smart plug (Model DSP-W215) that configurable via WPS, allows you to control and monitor your electrical appliance via Android 4.0+ and iOS6+ mobile devices, and it even has an overheating protection mechanism that can apparently detect if the plug or the device itself overheats. Let’s go through the technical specifications: Wi-Fi – IEEE 802.11n (According to pictures found via FCC filings, the chipset is Atheros AR1311_AL1A) Misc – Power / Status LEDs, On/Off button Dimensions – 9 x 6.10 x 3.56 cm (3.54″ x 2.40″ x 1.40″) Weight – 125 g (4.41 ounces) Power Input – 100 to 125 V AC / 5W maximum power consumption Temperature Range – Operating: 0 to 40 °C, Storage: -20 to 65 °F Humidity – Operating: 10% to 90% non-condensing, Storage: 5% to 95% non-condensing Based on these specs, since it can only work between 100 […]

$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 […]

Mediatek MT8639 Wi-Fi Display SoC to Support 802.11ac, NFC

Wi-Fi display technologies such as Miracast and Airplay allow you to conveniently mirror your mobile device on your TV without the needs to connect any cables, and for over about a year we’ve seen Miracast, Airplay, DLNA, and EZcast dongles on the market. In theory, this is all great, but in practice, this is all too often disappointing because of lag, sometimes the video quality is very poor, and sometimes it won’t connect. Mediatek is now working on MT8639 supporting 802.11ac which will hopefully offer a more consistent and enjoyable user experience, if your mobile device also supports 802.11ac. Here are the main features of the chip: ARM Cortex A7 @ 1 GHz Wi-Fi Dual band 2.4Ghz and 5 GHz 802.11 b/g/n/ and 802.11ac Wifi-Direct, Wi-Fi SoftAP, and Wi-Fi Bridge support Optional NFC support Wi-Fi Display – DLNA, Airplay, Miracast, “Windows” mirror Video Output – HDMI 1.4 / MHL 2.0 […]
