Lantronix Unveils xPico Wi-Fi Module For the Internet of Things

With Texas Instruments SimpleLink Wi-Fi CC3000 and Qualcomm Atheros AR4100P embedded Wi-Fi processors that fully handle Wi-Fi internally, and transfer data to an MCU with an SPI interface, and solutions such as Electric Imp, there are already ways to add Wi-Fi at relatively low cost to appliances. There’s now another solution available on the market with Lantronix xPico Wi-Fi Module. Listed features and specification of xPico Wi-Fi: SoC – ARM Cortex M3 class processor with 1MB on-chip Flash and 128 KB SRAM Storage – SPI Flash storage Wireless LAN Interface IEEE 802.11 b/g and IEEE 802.11n (single stream) WLAN interface (2.4 GHz only) IEEE 802.11 d/h/i/j/k/w/r WPS 2.0 support u.FL connector for external antenna Serial Interface Two Serial CMOS Ports (3.3V, 5V tolerant) 300 to 921.6 Kbps Flow control XON/XOFF, RTS/CTS (SPort 1 only) Lantronix tunneling application (SPort 1 only) Host Interface – Dual Serial Port, SPI, USB 2.0 (device), […]

Control your DSLR Camera via Wi-Fi using an Android mini PC and a Tablet

DSLR Controller is a paid Android app (beta) that uses your Canon EOS DSLR camera USB port in order to control it and access the camera live view with a tablet or smartphone. That may be useful, but it’s much better if you can roam a bit, and are not limited by the USB cable length. That’s why the application has been improved some time ago in order to use 2 Android devices, usually smartphones or tablets. One device is connected via USB to the DSLR camera, and act as a Wi-Fi access point, and the other device connects via Wi-Fi to allow full control of the camera. However, you don’t really need a screen on a Wi-Fi access point, so instead of using mobile devices, the developers decided to use an Android mini PC, specifically CX-919, which is just one of the many RK3188 mini PC available today, coupled […]

Texas Instruments Introduces SimpleLink Wi-Fi CC3000 BoosterPack

Texas Instrument launched SimpleLink Wi-Fi CC3000 in Q1 2012 in order to bring WiFi connectivity to any device including 8-bit or 16-bit MCU, as CC3300 internally handled all networking tasks, and exchange data with the MCU via an SPI interface. This Wi-Fi processor allows to use Wi-Fi for data transmission for the Internet of Things, and offers much better battery than other system relying on software to handle network traffic. Today, the company has just announced SimpleLink Wi-Fi CC3000 BoosterPack, a low cost evaluation platform that works with both MSP430 and Tiva C Series LaunchPad evaluation kits, and sells for $35. SimpleLink Wi-Fi CC3000 BoosterPack features and benefits as seen in the press release: SmartConfig technology: One-step Wi-Fi configuration using smartphones, tablets or PCs Easy network setup for display-less (headless) devices Simultaneous multiple device provisioning iOS, Android and Java sample applications available Royalty-free software Flexible memory size – Small memory foot print […]

$88.50 Jesurun NX003II Quad Core mini PC Comes with a Webcam and an External Wi-Fi Antenna

Do you remember MK812, a dual core mini PC with a built-in camera, and an external high-gain Wi-Fi antenna? Well, I’ve just noticed a similar device called Jesurun NX003II on DealExtreme, but instead of the dual core processor (RK3066) and 1GB RAM, it comes with Rockchip RK3188 quad core Cortex A9 processor, 2GB RAM, and yes, the camera and external antenna are still there. Jesurun NX003II Specifications: SoC – Rockchip RK3188 Quad core Cortex A9 @ 1.6Ghz with Mali-400 MP4 GPU System Memory – 2GB DDRIII Storage – 8GB NAND Flash + microSD card (up to 32GB) Connectivity: Wi-Fi IEEE 802.11 b/g/n with external Antenna Bluetooth v2.1 Video Output – HDMI 1.4 (1080p, 3D support) Video Codecs – MPEG1/2/4, H.264, VC-1, Divx, Xvid, RM8/9/10, VP6 Audio Codecs – MP3, WM, WMA, WAV, OGG, AAC, MPEG Audio, PCM LPCM, M4A, AC3, DTS Camera – Built-in 2.0MP camera USB – USB OTG […]

Wi-Fi Performance Comparison for Android Media Players and HDMI Sticks

If you’re mainly using your Android mini PC or STB to stream videos over the web or your local network, Wi-Fi performance is actually more important than CPU performance, and I’ve recently had quite a few issues with Wi-Fi with both T428 (RK3188 / Broadcom Wi-Fi module) and CS868 (AllWinner A31 / Realtek Wi-Fi module), which were only fixed after upgrading my router firmware. So I’ve decided to re-test most of the mini PCs I own with the upgraded router firmware, and the number are highly confusing, and I found out there’s probably be no easy to way to estimate the overall Wi-Fi performance of any device, and it’s most probably highly dependent on the router used, and its firmware version. My router is TP-LINK WR940N, a 300 Mbps Wireless N router with three antennas. Since I bought it, I had never upgraded the firmware (3.9.18 Build 100104 Rel.36350n) from […]

Adding Wi-Fi to Emcraft Systems K70 SoM

Emcraft Systems K70 SoM is a system-on-module powered by Freescale K70 Cortex M4 micro-controller with enough RAM (64 MB) to comfortably run uClinux. They used to charge $99 for their uCLinux BSP, but it’s now free of charge, and the company also provides full hardware and software documentation, including a getting started guide, schematics and BoM for the baseboard, application notes and more… Many of their clients want to use Wi-Fi with K70 SoM, and it can easily be done by using Wi-Fi USB dongles based on Ralink RT5370 chipset such as D-Link DWA-140 (H/W rev B3) or Comfast CF-WU815N. Emcraft has provided detailed instructions to do so with K70 SoM, their latest baseboard (SOM-BSB-EXT) and a demo image based on their uClinux BSP. I’ll summarize the instructions to use K70 SoM as a Wi-Fi access point below. Connect the baseboard and K70 SoM with an Ethernet cable, a mini […]
