Semtech Improves LoRa Efficiency and Range, Reduces Footprint with SX1261, SX1262, and SX1268 LoRa Chips

LoRa is one of the most popular LPWAN technology deployed around the world with chips made by Semtech, as it allow long range, low power communication at low bitrate, and is especially useful for asset tracking, smart parking, and all sort of remote monitoring of persons (e.g. elderly fall for seniors) or assets (e.g. leak detection). Depending on your applications, i.e. data size and update frequency, a coin cell battery can last up to 10 years The company has now introduced the second generation LoRa technology with three new RF chips that are 45% smaller, reduce power consumption by 50% (4.5 mA) , and extend range by 20%. The new chips also offers a high-power transmit option (+22 dBm), supports FSK modulation for migration to LoRaWAN from legacy protocols, and includes a new spreading factor for dense networks. Full list of new features listed by the company: 50% less power […]

SKIIN Smart Underwears Support Energous’ WattUp Near, Mid, and Far-Field Wireless Charging

SKIIN-Underwear-Bra-T-Shirt

Near-field wireless charging has been around for several years, but for wireless charging to become really disruptive it needs to work at a distance, and Energous has been working on mid and far-field technology with their WattUp transmissive to charge devices respectively on the desk (mid-field) or in the room (far-field). You need to have compatible devices to work with the technology, and wearables are a prime target, but I was expecting fitness trackers or smartwatches to embed the technology at first, but instead one of the first WattUp compatible wearables are smart underwears from SKIIN. The module found in SKIIN underwears and bras have many of the same features as your typical fitness tracker and some extras: Sensors ECG sensors for Heart Rate Monitoring (HRM) Accelerometer and Gyroscope to measure motion & posture BIA (Bioelectrical impedance analysis) to monitor water intake levels and how your sweat affects your hydration, […]

Lenovo Miix 630 2-in-1 Detachable Runs Windows 10 S on Qualcomm Snapdragon 835

Lenovo Miix 630 is joining other Qualcomm 835 powered always-on always connected Windows 10 PCs such as HP Envy x2 2017, and ASUS Novago TP370. Like its peers, the 2-in-1 laptop supports both WiFi and LTE connectivity, and promises ultra-long battery life for example up to 20 hours of local video playback. The device also includes a digital pen with 1024 levels of sensitivity, and a backlit keyboard. Another similarity is a high price, as Miix 630 pricing with keyboard and  digital pen will start at $799.99 in Q2 2018. Lenovo Miix 630 preliminary specifications: SoC – Qualcomm Snapdragon 835 processor @ up to 2.6GHz with Adreno 540 GPU System memory – 4GB RAM Storage – 128GB UFS 2.0 storage Display – 12.3″ WUXGA (1920×1200) touchscreen display Audio – Speaker and microphone (support for Cortana) Backlit keyboard Connectivity – 4G LTE and WiFi Camera – Infrared camera compatible with Windows Hello […]

ASUS Tinker Board S adds 16GB eMMC flash, to sell for $79.99

ASUS-Tinker-Board-S-Large

ASUS Tinker Board generated a lot of buzz on this blog when it launched last year as a large company like ASUS entered the maker market with a Raspberry Pi 3 competitor with more powerful and 4K capable Rockchip RK3288 processor. The company has now announced an update at CES 2018 with Tinker Board S with the same features, except for the additional of 16GB eMMC flash and a few other minor changes. ASUS Tinker Board S specifications: SoC – Rockchip RK3288 quad core ARM Cortex A17 processor up to 1.8 GHz with Mali-T764 GPU supporting OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1 System Memory – 2GB dual channel LPDDR3 Storage – 16GB eMMC flash + micro SD slot Video output & Display I/F 1x HDMI 2.0 up to 3840×2160 @ 30 Hz with HDMI CEC 1x 15-pin MIPI DSI supporting HD resolution Audio – 1x 3.5mm audio jack with […]

ZOTAC ZBOX PICO PI226 & PI336 Gemini Lake Mini PCs Unveiled with Celeron N4000/N4100 Processor

ZOTAC is now showcasing their first Gemini Lake based mini PCs at CES 2018 with ZBOX PICO PI226 & PI336 models powered respectively by an Intel Celeron N4000 dual core processor, and Intel Celeron N4100 quad core processor. ZBOX ZBOX PICO PI226 The model is similar to ZOTAC PI225 reviewed by Linuxium a few weeks ago, and the company had to disable turbo mode in PI225 in order to keep temperature under control. The company placed it in the VESA mount for the event, and at first I though it may help with cooling, but Linuxium (see comments) tried with PI225, and heat dissipation was not improved. ZOTAC PI226 specifications: SoC – Intel Celeron N4000 dual core Gemini Lake processor up to 1.1/2.6 GHz with 12EU Intel UHD Graphics 600 @ up to 650 MHz; 6W TDP System Memory – 4GB LPDDR4 Storage – 32GB eMMC flash, micro SD card […]

NVIDIA Xavier AI SoC Now Sampling, DRIVE IX & DRIVE AR SDKs Announced

Well over a year ago, NVIDIA introduced Xavier, their next generation self-driving and artificial intelligence processor, with eight custom ARM cores, a 512-core Volta GPU, and support for 8K video encoding and decode. A few months ago, the company provided some more details and unveiled NVIDIA DRIVE PX Pegasus A.I. computer for level 5 autonomous driving with two Xavier processors and two NVIDIA next-generation GPUs delivering a total 320 TOPS of computing power. For that it’s worth, 320 TOPS is about 3200 times more powerful than Intel Movidus Neural Network Compute Stick. CES 2018 has now started, and NVIDIA made several announcement related to gaming and automotive markets, and confirmed Xavier is now sampling to select customers. What’s really new from the announcement is the addition of two new SDKs (software development kits) for the processor beside the original NVIDIA DRIVE AV autonomous vehicle platform: DRIVE IX – Intelligent experience […]

Samsung 8K QLED TV Uses Artificial Intelligence to Upscale SD Content to 8K Resolution

You’ve probably read how artificial intelligence can be applying to modify photos, either repair them, or change the weather in photos from sunny to rainy, and vice versa. Samsung unveiled an 85″ 8K QLED TV right before CES 2018, which should be news by itself, but that I found really intriguing is the TV’s artificial intelligence capabilities that will upscale standard and other resolution content to 8K resolution. The TV will take SD, Full HD or 4K sources runs it through machine learning algorithm to re-create details, reduce noise, and restore edges to bring them back to 8K picture quality. Not your usual “dumb” upscaling 🙂 The TV is said to be equipped with a database that studies and analyzes millions of images in advance to transform low-resolution content into high-resolution, and capable of selecting the optimal filter to convert the source to higher quality. Samsung then explains the images […]

Rockchip RK3399Pro SoC Integrates a 2.4 TOPS Neural Network Processing Unit for Artificial Intelligence Applications

Rockchip RK3399 (aka OP1) SoC was launched in 2016 with an hexa core Arm Cortex A72/A53 processor, Mali-T860MP4 GPU, support for 4K video decoding, and high speed interfaces like USB 3.0 and PCIe, as well as Gigabit Ethernet. The processor is found in Chromebooks, TV boxes, development boards, and other devices. The company has unveiled an upgraded “Pro” version of the processor at CES 2018. Rockchip RK3399Pro appears to have most of the same features as its predecessor but adds a neural network processing unit (NPU) delivering up to 2.4 TOPS for artificial intelligence and deep learning applications. The company claims that compared to traditional solution, the computing performance of typical deep neural network Inception V3, ResNet34 and VGG16 models on RK3399Pro is improved by almost one hundred times, and power consumption is less than 1% than A.I. solutions implemented using GPU acceleration. Based on the information provided in the […]
