[Update: Atomwear has been renamed to Vigekwear due to (Intel’s) copyrights infringement]. Giayee is a company mainly manufacturing Android tablets, thin clients, and mini PCs, but their latest product, called Atomwear, is a Bluetooth Low Energy (BLE) development kit based on Nordic nRF51822 chipset that comes with various modules such as battery charger, accelerometer, gyroscope, OLED display, heart rate monitor, etc… which connect together via 24-pin connector on a standard rigid baseboard or a flexible printed circuit (FPC). All modules are connected via the same 24-pin connector with power, I2C, SPI, UART, ADC, and GPIOs signals. The baseboard and FPC both contain 6 such connectors connected in parallel for up to 6 modules, and two baseboard can be connected together via a bridge circuit to accept more modules. The minimum configuration is with a BLE MCU module, and a power module. The different boards and modules are listed as follows: […]
Hardkernel Unveils $30 Raspberry Pi Compatible Module with RTC, ADC, and LiPo Battery Support
Hardkernel is better know for its ODROID boards powered by Samsung Exynos SoC. So I was surprised to discover ODROID-W, “a miniature computing module which is fully compatible with all software available for the Raspberry-Pi”. Software compatible, really? Yes, because they used the same Broadcom BCM2835 SoC found in the Raspberry Pi, packaged it in a smaller form factor, while keeping HDMI, USB, and CSI interface, and expansion headers, and all that for $30, plus just $9 for shipping. Let’s go through ODROID-W specifications first: SoC – Broadcom BCM2835 ARM1176JZ-F processor @ 700 Mhz with VideoCore IV GPU System Memory – 512MB LPDDR2 (Samsung K4P4G324EB PoP) Storage – microSD slot + eMMC socket (bottom of the board) Video Output – micro HDMI (with NXP IP4791CZ12 protection IC) USB – micro USB connector, and USB host (not soldered) Expansion Headers: R-Pi compatible 26-pin expansion header (through holes) R-Pi compatible 15-pin CSI […]
Freescale WaRPBoard Reference Platform for Wearables is Now Available for Pre-order
Back in January, Freescale announced WaRP (Wearable Reference Platform) comprised of the WaRPboard, a tiny board based on Freescale i.MX 6SoloLite running Android, and a daughter board with KL16 Cortex M0+ MCU and several sensors. The company collaborated with Revolution Robotics for the hardware design, and Kynetics for the software, and the platform is now available for pre-order for $149, and a few more details have surfaced since my first article. The hardware specifications of WaRP are as follows: WaRPboard: SoC – Freescale i.MX 6SoloLite Cortex A9 processor @ 1GHz with 2D graphics Vivante GC355 and GC320 GPUs. System Memory – LPDDR2 (Micron Multi-Chip Package) Storage – 4Gbit eMMC (Same Micron MCP chip as for RAM) Connectivity – WLAN and Bluetooth 4.0 LE via Murata LBEH17YSHC Display I/F: MIPI DSI for LCD display + touchscreen EPCD for E-Ink Display Sensors – Xtrinsic FXOS8700CQ, 6-Axis Sensor with Integrated Linear Accelerometer and Magnetometer. Daughtercard: […]
Imagination Technologies Unveils Low Power Low Footprint PowerVR GX5300 GPU for Wearables
Up to now most wearables are based on MCU solutions or derived from mobile platforms, which may either not provide the advanced features required by users, or consume too much power and take more space than needed. With Ineda Dhanush and Mediatek Aster, we’ve already seen silicon vendors design wearables SoCs, and now Imagination Technologies has just announced PowerVR GX5300 GPU targeting wearables with support for OpenGL ES 2.0, 480p to 720p resolution, and using 0.55mm2 silicon area based on 28nm process. PowerVR GX5300 GPU will be support Android, Android Wear, and Linux based operation systems, and according to the company has the following key features: Unified shaders – The TBDR graphics architecture offers unified shaders where vertex, pixel and GPU compute resources are scaled simultaneously. Low power and high precision graphics – All PowerVR GPUs offer a mix of low (FP16) and high precision (FP32) rendering and implement the […]
More Details on Mediatek MT2502 Aster SoC and Linkit Platform for Wearables (Video)
Last month, Mediatek announced their Mediatek MT2502 SoC for wearables, codenamed Aster, as well as the Linkit development platform targeting the developer’s community. But at the time they did show the actual hardware, and thanks to Charbax we know have more interesting details about Aster and Linkit. First they compare a design based on Aster to Samsung Galaxy Fit wearable band, and show why it uses less space, will cost less, and they claim over twice the battery life. Simple and smaller design (~36% reduction in size) Aster solution – MT2504 (6.2 x 5.4 mm) plus all required resistors, capacitors and inductors require 89.97 mm2 Galaxy Fit – MCU. Bluetooth Transceiver, external memory, a linear charger, and all required resistors, capacitors and inductors require 140.97 mm2 Battery life – Samsung Galaxy Fit is supposed to last between 1 and 1.5 days on a charge, whereas devices based on Aster should last about […]
Review of Vidonn X5 Fitness Tracker
With all the activity / fitness trackers on the market now, I wanted to try on,e but I did not find they were good value, but when DealExtreme sold Vidonn X5 fitness tracker for about $27, I decided to jump and have a try. You can synchronize data with Bluetooth 4.0 Low Energy enabled Android 4.3+ and iOS mobile device, but I don’t have any, so instead I used a netbook running Windows XP for initialization and fitness data tracking. Vidonn X5 Unboxing Pictures I was quite surprised how fast I received the parcel. It was shipped by China Post, yet I received it within 9 days. Usually small items can be found without package and shipped in bubble envelopes, but this device comes in a relatively nice looking plastic box. The box just contains a user’s manual in Chinglish, and the fitness band. Two clips are used to fastness […]

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, […]
