Google Unveils $199 Acer C7 Chromebook Powered by Intel Celeron 847

After the new (ARM based) Samsung Chromebook released last month, Google announced the Acer C7 Chromebook based on an Intel Celeron processor at a cheaper price ($199 vs $249), but at the cost of shorter battery life and the addition of a fan. Beside the Celeron processor @ 1.1 GHz, the new Acer C7 Chromebook comes with 2 GB RAM, a 320 GB hard drive, features a 11,6″ display, weights 1.3 kg and the 37Wh battery can last for over 3.5 hours. Other features include Wi-Fi, Ethernet, Bluetooth. The Acer Chromebook comes with 3 USB 3.0 ports, HDMI & VGA video outputs, a 2-in-1 card reader, a webcam, built-in stereo speaker and audio jacks for headphones and microphones. Whereas the Exynos 5250 can boot in less than 10 seconds (Thanks partialy to the SSD), the new Acer Chromebook boots up in 18 seconds which is not too bad. Google will […]

Jesurun Xplus H25 Mini PCs with Rotating HDMI Port, DLNA Support

Jesurun Xplus H25 mini PCs are typical Android 4.0 AllWinner A10 and Rockchip RK3066 mini PCs, expect for one slight mechanical difference: The HDMI male port can rotate and possibly allow the mini PC to be inserted directly into the TV in case where other may not. Of course, one option could always be to buy a cheap HDMI rotating adapter or an HDMI cable to connect the device, but I find having this option within the device is neater. Let’s look at the specs of the single core version: SoC – AllWinner A10 with Mali-400 GPU System Memory – 1GB RAM Storage – 4GB NAND Flash + TF card slot USB – 1x USB 2.0 OTGX + 1x USB HOST + 1x mini USB HOST WiFi – 802.11b/g/n Video Container Formats – AVI, MKV, TS, TP, TRP, M2TS, MPG, MP4, M4V, MOV, VOB, MVC(3D) ISO, IFO, DAT, WMV, ASF/RM, […]

£20 PiFace Digital I/O Expansion Board for the Raspberry Pi Board

Elements14 has just announced that it will be the exclusive distributor of the PiFace Digital I/O expansion board for the Raspberry Pi and sell it for 20 GBP. The PiFace Digital board, whose first prototype was unveiled back in May, is an expansion board allows you to interact with the outside world and control and sense physical devices such as lights, motors and sensors like the Gertboard, but has the advantage of fitting neatly on the top the Raspberry Pi, which should allow it to be used with some of the existing Raspberry Pi cases. Detailed technical information is scarce on the Mk2 version of PiFace Digital (the one sold by Elements14), but the board apprars to include 2 relays (which can be disabled by jumper), a buffered I/O interface with 8 inputs and 8 outputs, and buttons & LEDs. If will primarily be an education platform and free educational tools […]

$17.50 STMicroelectronics M24LR Discovery Kit For NFC/RFID Batteryless Applications

STMicroelectronics has announced the M24LR Discovery Kit, a low cost development platform for NFC or RFID applications with energy-harvesting capabilities. This devkit is aimed at accelerating the design and development of batterlyless applications such as phone and tablet accessories, computer peripherals, electronic shelf labels, home appliances, industrial automation, sensing and monitoring systems, and personal healthcare products. The M24LR Discovery Kit consists of two boards: an RF transceiver board with a 13.56MHz multi-protocol RFID/NFC transceiver driven by an STM32 32-bit microcontroller A battery-less board that includes ST’s dual-interface EEPROM memory IC, an ultra-low-power 8-bit microcontroller (STM8L) and a temperature sensor. Here are the key features of the boards: M24LR board M24LR04E-RMN6T/2 Dual Interface EEPROM with I2C and ISO/IEC 15693 RF interfaces, 4 Kbits of EEPROM and password protection in SO8N package STM8L152C6T6 8-bit microcontroller, with 8 Kbytes of Flash memory STTS751-0WB3F, low-voltage digital temperature sensor 20 x 40 mm inductive antenna […]

FRAM (Ferroelectric Random Access Memory) and Texas Instruments MSP430FR57xx MCUs

I’ve recently received a complementary book entitled “Texas Instruments FRAM MCUs for DUMMIES” sent by Mouser, that provides technical and practical information about FRAM (Ferroelectric Random Access Memory) – pronounced F-RAM – and Texas Instruments MSP430FR57xx MCU series which makes use of this relatively new type of memory. FRAM is a non-volatile memory with power and write speed & endurance characteristics that almost matches SRAM capabilities, and leave traditional Flash and EEPROM memory in the dust in terms of performance, as you can see from the table and diagram below. At constant speed, FRAM consumes 250x less than Flash/EEPROM. Please note the FRAM write speed also depends on the MCU used, and a MCU @ 8MHz can write the FRAM @ 1400 kBps (Source: TI). However, you won’t see this type of memory in devices like smartphones anytime soon because the maximum size currently manufactured is 1MB, density is higher […]

$444 Smartbeam Android 4.0 Media Player & Projector Powered by Telechips TCC8925

Android is now everywhere, from the ubiquitous smartphones and tablets to cars, cameras, satellites (no kidding), light bulbs (seriously) and more. Today is the first time I’ve come across a full sized projector running Android. The “Smartbeam” is a 2000 lumens 1280×768 (native) projector powered by Telechips TCC8925 with 512 MB RAM and 4 GB Flash running Android 4.0.4 (ICS), so the performance should be very similar to CX-01 mini PC. Here are the specs of this new device: SoC – Telechips TCC8925 up to 833 MHz System Memory – 512 MB RAM Storage – 4 GB NAND Flash WiFi – 802.11 b/g/n Display – 5.8″ Single LCD Panel Display Technology (cnxsoft: But I can’t find any display on any of the pictures…) Projector: Projection Lens – Manual Lens Resolution: Native SGA (1280*768 Pixels), Support Resolution QGA (1920 x 1200) Brightness (Typical) – LED lamp 2000 lumens, more than 320Lux […]

Digi Launches XBee-PRO 900HP RF Module With a Range of Up to 45 Km

Digi International has recently announced the XBee-PRO 900HP RF embedded module based on ADF7023 transceiver and Energy Micro Cortex-M3 EFM32G230 MCU @ 28 MHz. The company claims the module supports a line-of-sight range of up to 45 km with a high-gain antenna and data rates of up to 200 Kbps.45 km is not quite enough to communicate in space (100 km), but that’s still a pretty good range. Indoor / urban range is up to 600m. Here are the hardware specifications of XBee-PRO 900HP module: Processors – ADF7023 transceiver and Cortex-M3 EFM32G230 @ 28 MHz Frequency Band – 902 to 928 MHz, software selectable channel mask for interference immunity Antenna Options – Wire, U.FL and RPSMSA RF Data Rate – 10 Kbps or 200 Kbps Indoor/Urban Range – Up to 2000 ft (610 m) Outdoor/ Line-Of-Sight Range – Up to 9 miles (14 km) w/ dipole antenna; Up to 28 […]

Ugoos UG007 Android 4.1 HDMI TV Stick Features Bluetooth and Rockchip RK3066 Processor

There are many low cost Android mini-PCs on the market today, but most of them can only support 2.4 GHz wireless connection (e.g. for keyboard, mouse or “fly mouse”) via an external USB dongle, and very few have built-in Bluetooth support. If you want the performance of UG802 mini PC and use your existing Bluetooth keyboard, game controller, headset…, Ugoos UG007 mini PC might be a good option since it features Rockchip RK3066 dual core processor and comes with Bluetooth v2.1 + EDR support. Here are the specs of Ugoos UG007: SoC – Rockchip RK3066 Dual ARM Cortex-A9 processor clocked @ up to 1.2 GHZ with Mali-400MP4 Quad-core GPU, System Memory – 1GB DDR3 RAM Storage – 8GB NAND Flash + micro SD card slot (Up to 32 GB) Connectivity: Wifi – 802.11 b/g/n Bluetooth 2.1 + EDR (Mediatek MT6622) 3G support via external 3G USB dongle USB – 1x […]
