Samsung UFS micro SD Card Alternatives Promise High Sequential and Random I/O Performance

UFS (Universal Flash Storage) chips are now commonly found in premium smartphones, but the UFS standard has also been published for removable cards, and Samsung has just introduced their first cards based on UFS 1.0 Card Extension Standard* for use in high-resolution mobile shooting devices such as DSLRs, 3D VR cameras, action cams and drones, as a new alternative to micro SD cards. Before getting into more details about the Samsung card, let’s go through the main features defined by UFS card specifications: Based on the UFS 2.0 standard and compatible with the UFS HCI 2.0 standard Supports MIPI M-PHY HS-Gear3, HS-Gear2 (optional), and PWM-Gear1 A detailed mechanical definition is defined by the JEDEC MO-320 outline Features common to embedded UFS 2.0 devices: Support for multiple logical units, each with configurable characteristics Reliable write and background operations Secure operations such as purge and erase to enhance data security Includes write […]

OpenCellular is Facebook’s (soon to be) Open Source Wireless Access Platform

A few months after Canonical and Lime Micro LimeSDR open source software defined radio aiming to be used as a development platform, but also as the base for low cost cellular or other wireless base stations, Facebook has announced their own open source wireless access platform with OpenCellular project whose goal is to lower the cost of Internet connectivity in remote areas where the infrastructure does not exist. This is how Marc Zuckerberg summarizes the project: We designed OpenCellular as an open system so anyone — from telecom operators to researchers to entrepreneurs — can build and operate wireless networks in remote places. It’s about the size of a shoe box and can support up to 1,500 people from as far as 10 kilometers away. Along with our solar-powered aircraft Aquila and high-bandwidth laser beams, OpenCellular is the next step on our journey to provide better, more affordable connectivity to […]

Smaller & Faster than Raspberry Pi Zero: Meet NanoPi NEO ARM Linux Development Board

Raspberry Pi Zero has two noticeable attributes compared to other Raspberry Pi boards: it’s smaller and it’s cheaper. FriendlyARM has now designed another model for their NanoPi family, that about 12% smaller, although not quite as thin at all due to its Ethernet jack and USB connector, and much faster than Raspberry Pi Zero, with NanoPi NEO board powered by Allwinner H3 quad core processor. NanoPi NEO specifications: SoC – Allwinner H3 quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz System Memory – 256 or 512 MB DDR3 Storage – micro SD card slot Connectivity – 10/100M Ethernet USB – 1x USB 2.0 host ports, 1x micro USB OTG port, 2x USB via headers Expansion headers 24-pin header with I2C, 2x UART, SPI, PWM, and power signals 12-pin header with 2x USB, IR pin, microphone and Line OUT signals Debugging – 4-pin […]

WeTek Hub Amlogic S905 TV Box Gets Android 6.0 Marshmallow Firmware

Amlogic S905 TV boxes are currently running Android 5.1, but a few are now getting Android 6.0 support including MXQ Plus, and soon K1 Plus. VideoStrong refused to provide the firmware for MXQ Plus as I did not own the box, but WeTek has already provided their latest beta Android 6.0 firmware to testers and reviewers working on WeTek Hub, which I plan to review next week with Android 5.1 first. The main changes with Android 6.0, beside the expected better performance, are support audio HAL 61937 pack allowing HD audio pass-through on all apps, as well as Microsoft PlayReady 3.0 permitting Ultra HD 4K DRM video streaming. Eventually, Android 6.0 update will be available through OTA, but currently the beta firmware (DB-J9-wetekhub-marshmallow-ota-2016-07-06_12-00-03.zip) needs to be copied to a micro SD card, and update through Recovery after wiping data and media.

Nordic Semiconductor nRF52832 Cortex-M4 ANT & Bluetooth LE SoC Gets Even Tinier

Nordic Semiconductor nRF52832 is a Bluetooth 4.2 LE SoC based on an ARM Cortex-M4F core that was first released about a year ago in a QFN48 package targeting IoT and Wearables. But if your application is really tight on space and the 6x6mm package is just too big, the company has just introduced a 3.0×3.2mm WL-CSP (Wafer Level Chip Scale Package ) package for nRF52832 decreasing the area to about one quarter of the QFN package The specifications are exactly the same as the QFN, but let’s see what we’ve got in that 9.6mm2 package: MCU Core – ARM Cortex-M4F @ 64 MHz with DSP & FPU, 512kB Flash and 64kB RAM 2.4 GHz radio for ANT, Bluetooth 4.2 LE, and Gazell connectivity; 5.5mA peak RX/TX currents; on-chip RF Balun On-chip NFC tag Peripherals – 3x Master/Slave SPI, 2x Two-wire interface (I²C), UART (RTS/CTS), 3x PWM, Digital microphone interface (PDM) Security […]

RisingHF IoT Discovery is a LoRaWAN Evaluation Kit for Raspberry Pi

There are many current and upcoming long range low power wireless protocols for the IoT, but this morning I learned that South Korea launched a LoRa network (aka LoRaWAN), after another launch in the Netherlands earlier this year. While there are also some LoRa hobbyist kits such as LoraONE and LoPy being worked on, I decided to look on Aliexpress, but only got two products were listed: a LoRaWAN temperature and humidity sensor, and a LoraWAN USB modem. Both of them are made by a company called RisingHF. Among the products offered by the company, there’s a potentially interesting development kit called RisingHF IoT Discovery with the following components: 1x Raspberry Pi board 1x RHF0M301 LoRa Gateway based on Semtech SX1301 1x RHF4T002 adapter for Raspberry Pi and RHF0M301 1x RHF3M076 LoRaWAN USB AT Modem End point to connect to computer. It operates at 434MHz, 470MHz,868MHz, and 915MHz 3x RHF76-052 […]

Allwinner and Qualcomm Partner on Android and Windows 10 LTE Tablets

Allwinner, a leading tablet SoC vendor, and Qualcomm have decided to collaborate, and introduced three new LTE tablet reference designs based on Qualcomm Snapdragon 425, 430, and 435 available to Chinese OEMs, on top of Snapdragon 210, 212 and 410 designs released last year. The full technical technical details about the reference designs are only available to OEMS who signed an NDA, but the key specifications are as follows: SoC – Qualcomm Snapdragon 420, 430, 435 application processors System Memory – 2G DRAM Storage – 32GB internal memory Connectivity – CAT 6 LTE band The tablet will run Android, but Windows 10 is also being worked on. The agreement only covers tablets, so Allwinner will not be involved in LTE smartphones. Since both Allwinner and Qualcomm are silicon vendors, and competitors, you may wonder why they’ve partnered. Allwinner only provides WiFi and Bluetooth tablets with their own processors, so partnering with Qualcomm allows then to […]
