openPicus Introduces Wi-Fi and GPRS IoT Kits Powered by Microchip PIC24 MCU

openPicus has launched two new development kits for the Internet of Things with either Wi-Fi or GPRS connectivity, based on their FlyportPRO modules featuring a 16-bit Microchip PIC24 MCU, and sharing the same baseboard. These kits can be used as a Web server with firmware update over the air (FOTA) (Wi-Fi version only) among other things, and support TCP, UDP, FTP, & HTTP protocols, as well as MQTT (Message Queue Telemetry Transport), a light weight messaging protocol running on top of the TCP/IP protocol, used when a small code footprint is required and/or network bandwidth is limited. openPicus FlyportPRO Wi-Fi and GPRS modules share mostly the same specifications: MCU – Microchip PIC24FJ256GB206 16-bit MCU @ 32 MHz with 256KB Flash, 96KB RAM External Storage – 16Mbit Flash memory (for FOTA), 64Kbit EEPROM Connectivity GPRS Module – SAGEM HILONC GPRS Transceiver (quad band: 850, 900, 1800, 1900 MHz) with uFL connector for external […]

Review of EM6Q-MXQ Android Quad Core Media Player

After taking a few pictures of Eny EM6Q-MXQ Android media player, it’s time for a full review. I’ll first give my first impressions and go through the user interface, test video playback, test the system, network, and storage performance, try a few games, and check various hardware ports are working as they are supposed to do. First Boot, Settings and First Impressions I’ve inserted two AAA batteries in the provided infrared remote control to check it’s working, and it’s usable in the main user interface and XBMC, but once you start using most Android apps it’s useless, so I quickly switched to Mele F10 Deluxe air mouse. Before powering up the device, I’ve connected an HDMI cable, an Ethernet cable, and made with use of the 4 USB ports by connecting two RF dongles (Air mouse and gamepad), a USB hard drive, and a UVC USB webcam. The box lacks […]

Getting Started with LinkIt ONE Development Kit for Wearables & IoT

After going through WRTnode Quick Start Guide, it’s now time to play with LinkIt ONE, the IoT development board from Mediatek designed by Seeed Studio. LinkIt ONE is the first Hardware Development Kit (HDK) for Mediatek LinkIt, so there may be a LinkIt TWO, and/or other hardware platforms in the future. LinkIt ONE specifications Let’s quickly go through the specifications first: Processor – Mediatek MT2502A (Aster) ARM7 EJ-STM processor @ 260 MHz System Memory – 4 MB Storage – 16MB Flash for firmware + micro SD slot shared with SIM slot for up to 32GB additional storage Connectivity: Wi-Fi – 802.11 b/g/n (MT5931) with external antenna Bluetooth – BR/EDR/BLE(Dual Mode) GPS – Mediatek MT3332 with external antenna GSM/GPRS – 850/900/1800/1900 MHz band, Class 12 GPS with external antenna Audio – 3.5mm headphone jack (including mic support) – Support for MP3, AAC, and AMR codecs. Serial – Software Serial (Serial), and […]

Getting Started with WRTnode OpenWRT Development Board

Seeed Studio sent me two nice little boards that can be used for IoT development: WRTNode and LinkIt ONE. Today, I’ll show pictures of WRTNode and accessories, and go through the “starting guide“, and will test LinkIt ONE board a few days later. WRTnode Unboxing I’ve received WRTnode by Fedex, and the board is stored in a plastic box. Inside the box, you’ll find the board, a “special” USB used to power the board and as an OTG adapter, a piece of paper with useful links (Wiki), and some WRTnode stickers. Any micro USB to USB cable can be used to power the board, but this cable is useless to connect USB devices such as flash drives, webcams (OpenCV is supported), Bluetooth dongles, and so on. You could even connect a USB hub to connect multiple USB devices as shown below. I’ve also taken a picture of both sides of […]

WeIO is an Open Source Hardware IoT Board Programmable from a Web Browser (Crowdfunding)

WeIO is an open source hardware board for the Internet of things with Wi-Fi connectivity and lots of I/Os designed by nodesign, a French based startup, in collaboration of 8devices, the makers of the Carambola boards. WeIO is powered by an Atheros AR9331 SoC running OpenWRT as well as an NXP LPC MCU for faster handling of I/Os and support for analog I/Os. One interesting aspect of this board is that it can be programmed via a web browser using HTML5 or Python, and it does not rely on the Cloud to store data. WeIO hardware specifications: SoC – Atheros AR9331 MIPS 24K Wireless SoC @ 400 MHz MCU – NXP LPC11xx ARM Cortex M0 MCU for analog I/O and real-time H/W interfaces System Memory – 64 MB DDR2 Storage – 16 MB flash + micro SD slot Connectivity – 802.11 b/g/n Wi-Fi with on-board antenna (AP and STA modes), […]

Review of Kingnovel K-R68 (R6) Android Mini PC

I’ve already listed specs, and shown a few pictures of Kingnovel K-R68 (R6) Android media player based on the latest Rockchip RK3288 quad core processor. I’ve now gone through all my usual tests, so today, I’ll write the review, going through the user interface, testing video playback, reporting one various performance benchmarks including network and storage performance, tested most hardware features, and played a few games. First Boot, Settings and First Impressions Albeit there’s an infrared remote control with the device. I’ve not used it all, especially, as we’ll see below the default user interface is the stock Android home screen. As usual, I’ve connected an RF dongle to use Mele F10 Deluxe air mouse. Before powering up the device, I’ve also connected an HDMI cable, a USB hard drive, and an Ethernet cable. Albeit there’s a power button, the device will boot automatically as you connect the power adapter, […]

W908I & W908II Wi-Fi Smart Sockets Support US, EU, UK, or AU Plug Types, Up to 4400W Power

I’ve had a look at several Wi-Fi smart sockets recently. Broadlink SP2 comes with a Chinese plug and supports power monitoring (About $40), Kankun KK-SP3 is more basic but sells only for $20, and runs OpenWRT, and Orvibo Wiwo S20 does not support power monitoring either, but is available with US, Europe, United Kingdom or Australia plug (About $40). If you want a Wi-Fi smart socket with a EU plug, there’s another option: W908I selling for $32 on Chinavasion. Based on the manufacturer website (HaiDian Technology) however, there are four W908I models with US, EU, UK, or AU plugs, as well as four W908II models with a higher power ratings (4400W). Instead of just one socket like socket models, it features a 3-pin socket, a 2-pin socket, and a USB port for charging devices. W908I / W908II specifications: Wi-Fi 802.11 b/g/n Sensitivity – 802.11b: < -84dBm; 802.11g: < -68dBm Output […]

Xiaomi Mi Wi-Fi Mini 802.11ac Router Can Now Be Purchased for $45

Ever since TV boxes with 802.11ac capabilities have been listed, I’ve been looking at purchasing a router with the latest Wi-Fi standard since I would then be able to test 802.11n at 2.4 and 5 GHz, as well as 802.11ac. The vast range of prices got me confused at first, but an article on Connectedly helped me clear things out. One of the most important factor is the different classes of Wi-Fi routers as shown in the table below. The class nomeclature is based on the Wi-Fi standard (AC or N) with a number corresponding to the rounded sum of the maximum throughput at 2.4GHz and 5GHz. Based on this table, and my limited budget ($100), I decided to look for AC1200 or greater routers, and I found one for TP-LINK Archer C7 AC1750 router selling for $100 on Amazon. Awesome! So I went to look on local websites only […]
