Google Releases Android L (Lollipop?) Developer Preview

Google I/O is taking place right now in San Francisco, and the company made several announcements. Although they have not announced the full codename of Android 5.0, referring to the next version as “Android L” (Lollipop would be nice though), but they’ve already documented the key changes made to Android L, and a developer preview will be released later today (26 June), together with binary images for Google Nexus 5 and Nexus 7. Beside the smartphone and tablet developer preview, there will be 3 other SDKs for Android L: Android Wear SDK – Android for wearables with sync notifications, wearable apps, data transfer APIs, and voice actions, e.g. “Ok Google, call mum”. Android TV Preview SDK – Android for TVs with pre-built fragments for browsing and interacting with media catalogs, in-app search, and recommendations. Android Auto SDK – Android for the car with apps featuring consistent user experience between vehicles, […]

List of Rockchip RK3288 Android TV Boxes So Far

In the previous years, you’d normally learn about new devices as they get listed on Alibaba or Aliexpress, and that’s how I built my – now very incomplete – list of Rockchip RK3188 based devices. But now companies seem to be anxious to let people know about their new devices even before they hit the market, and albeit I’ve been told full production of Rokchip RK3288 powered Android TV boxes is only planned by the end of July, many companies are already showing off their new devices, even though only the PCBA may be ready, or in development. Let’s go through the list of Rockchip RK3288 quad core Cortex A17 media devices that’s known (to me) so far: No brand D368 – HDMI 1.4 TV dongle with 1 or 2 GB RAM, 4, 8 or 16 GB flash, Wi-Fi 802.11 b/g/n/ac + (optional) Bluetooth, and 2x USB host ports. No […]

Low Power Mode (Suspend to RAM) in uCLinux for Freescale Kinetis K70 MCU

All ARM based micro-controllers and processors implement multiple power mode in order to save optimize power usage depending on the tasks. However, I’ve been told by some hobbyists/developers/makers that low power modes are not always implemented in Linux, especially for low cost systems either because of hardware limitations or the software is not implemented. EmCraft Systems has just released their latest embedded (uC-) Linux distributions for the MCU boards, and one of the features now available is “suspend to RAM” for their K70 SoM development kit, based on Freescale Kinetis K70 Cortex M4 MCU, which consume just around 600 to 700 uA @ 3.3V (2 to 2.3 mW) in this low power mode. They have connected a multimeter to measure the current drawn at different power modes. If you want to know all the details, you should probably read the company’s article on “Linux Low-Power Mode on Kinetis“, but I’ll […]

MK918 Android TV Box Powered by Rockchip RK3188T Sells for $50

MK918, also known as K-R42-1, CS918, or MK888, is an Android TV box powered by Rockchip RK3188T with 2GB RAM, and 8GB Flash. This is a pretty standard device, and I already featured it, but GeekBuying is selling the device for $49.99 as part of their second anniversary, which looks to be good deal, but it turns out some Aliexpress sellers are also doing promotions for about the same price ($50+). The promotion on GeekBuying will last about on more day, and around 50 units are available, and on Aliexpress promotions runs between 1 and 3 more days. The usual price seems to be between $60 and $70, but I guess some companies may get rid off old stocks with products based on Amlogic S802 already there, and Rockchip RK3288 and AllWinner A80 products soon to hit the market. Let’s remind ourselves of the complete specs: SoC – Rockchip RK3188T […]

CubieTruck’s DVK570 Daughter Board and Add-ons (GPS, Zigbee, Sensors, RS485, and SPI Flash)

CubieTruck is one of the development boards made by CubieTech. It is powered by AllWinner A20 with 2GB RAM, Gb Eternet, various ports, and supports Android and multiple Linux distributions. Waveshare Electronics has just launched DVK570 daughter board for the CubieTruck which adds support for TV in and out, a buzzer, and headers to connect modules such as GPS, RS485, an SPI flash, a Zigbee module, a magnetometer, or a temperature sensor. Hardware features of DVK570 daughter board: CubieTruck Headers – 1x 30-pin header and  1x 24-pin header for connection with the CubieTruck Video – TVIN in, and TV Out interfaces (CVBS) Audio – 3.5mm Line IN interface Debugging – UART interface, micro USB port with USB to UART chip (Profilic PL2303) Expansions for add-on modules: 1x 4-pin I2C interface to connect I2C modules such as PCF8563 RTC Module, MAG3110 Board, and more 2x 6-pin UART interfaces (UART4 and 7) […]

Raspberry Pi Compute Module Development Kit Is Now Available for $200

The Raspberry Pi foundation announced a computer-on-module which they called the (Raspberry Pi) Compute Module that will be mostly software compatible with the Raspberry Pi board, and sell for $30 in quantities. They have now announced the availability of the development kit that includes a baseboard (called Compute IO board), display & camera adapter boards, as well as a 5V power adapter, jumper wires, and a USB cable. As a reminder the Compute Module has the following hardware specifications: SoC – Broadcom BCM2835 ARM 11 processor @ 700 MHz with Videocore IV GPU System Memory – 512MB RAM Storage – 4GB eMMC Flash SoM Connector – DDR2 200-pins SODIMM Dimensions – 67.6x30mm board which fits into a standard DDR2 SODIMM connector The Compute IO Board come with two micro USB connectors (one reserved for power), a USB 2.0 host port, two DSI ports for display, two CSI ports for a […]

AllWinner A33 Quad Core Processor to Cost $5 With PMIC, Tablets Starting at $40

With their latest A33 SoC, Allwinner may have put a nail in the coffin of dual core application processor for tablets, as Eva Wu, AllWinner’s Marketing Manager,  has just released some pricing info, and AllWinner A33 with AXP223 PMIC (Power Management Integrated Circuit) reference price is only $4.99, paving the way for ultra cheap quad core Android tablets. I’ve also been given some estimates for (factory) prices for different tablet’s types powered by AllWinner A33: About $40 for 7″ tablets (800×480) with 1GB DDR3, and 8GB Flash. About $45 for 7.85″ tablets (1024×768) with 1GB DDR3, and 8GB Flash. About $50 for 8″ tablets (1280×800) with 1GB DDR3, 8GB Flash. With four ARM Cortex A7 cores, a Mali-400MP2 GPU, and limited display resolutions, you won’t get an amazing user experience, but for a first tablet, or a kid’s tablet, it looks pretty good value. I estimate that Chinese stores may […]

HTC / Google Nexus 9 To Feature Nvidia Tegra K1 Dual Core 64-bit ARMv8 Processor

ARMv8 (64-bit ARM) architecture has been seen in servers, and announced in mobile SoCs, but, putting aside some Apple products, we have yet to see any consumer products based on the latest ARM architecture. But this will change soon, as HTC Volantis, which could become Google Nexus 9 based on the picture leaked via Android Police, will feature an “Nvidia Logan 64-bit” SoC, which can only be a Tegra K1 dual core ARMv8 SoC announced at CES 2014. HTC Volantis / Nexus 9 specifications: SoC – NVIDIA Tegra K1 (logan) dual core 64-bit Processor System Memory – 2GB RAM Storage – 16/32GB internal storage Display – 8.9″ Display at 2048×1440 (281ppi) Camera –  8MP main camera with OIS, 3MP front facing camera Audio – Stereo front-facing speakers Dimensions – 22.63×15.19×0.79cm Weight – 418g, or 427g with LTE The assumption is that it will be released as the latest major release […]
