NanoPi NEO Core Board for 8$

The NanoPi NEO Core (abbreviated as “NEO Core”) is an alternative NanoPi NEO that works like a CPU board with male pin-headers. It has the same form factor as the NanoPi NEO and same pin descriptions. The connectors and ports are populated to pin-headers on the NEO Core. The NanoPi NEO Core has ESD protection for its MicroUSB port and TF card slot. In addition the NEO Core can have an optional onboard eMMC flash which is preferred by industrial customers.

The NEO Core uses a popular Allwinner H3 SoC and has onboard 256M/512M DDR3 RAM. FriendlyElec offers models with three eMMC options: 8GB/16GB/32GB and one that doesn’t have eMMC at all. FriendlyElec migrated UbuntuCore with mainline kernel 4.11 for it. FriendlyElec develops a Mini Shield for NanoPi NEO Core/Core2 which has the same form factor as the RPi 3. When a NanoPi NEO Core is connected to this Mini Shield the whole assembled module can be well fit into a common RPi 3’s case.

RoomSense Board offers multiple sensors including PIR motion detection

 

RoomSense Board is an Occupancy and Air Sensor.

It can detect movement and room conditions and connect over WiFi with a passive IR occupancy sensor, barometer, temperature and humidity sensors, and the Microchip ATSAMW25 module. Pre-flashed with the Arduino bootloader, the RoomSense is easily deployable as a home automation device by developers of all skill levels.

This tiny USB dongle uses a passive IR motion detector, and temperature, humidity and barometric sensors to monitor a room’s conditions and occupancy. The Microchip ATSAMW25 provides a SAMD21 Cortex-M0+ MCU and WiFi connectivity. It integrates easily with cloud IoT platforms such as MyDevices Cayenne.

Features

  • ARM Cortex-M0+ MCU at 48 MHz
  • 802.11b/g/n WiFi

LT8364 current mode step-up regulator has 2.8V – 60V input range

The LT8364 current mode, 2MHz step-up DC/DC converter has an internal 4A, 60V switch. [via]

It operates from an input voltage range of 2.8V to 60V, and is suitable for applications with input sources ranging from a single-cell Li-Ion battery to multicell battery stacks, automotive inputs, telecom power supplies and industrial power rails.

The device can be configured as either a boost, SEPIC or an inverting converter. Its switching frequency can be programmed between 300kHz and 2MHz, enabling designers to minimize external component sizes and avoid critical frequency bands, such as AM radio.

512Gbyte embedded universal flash memory in production

Samsung Electronics has begun mass production of what the company claims to be the industry’s first 512-gigabyte (GB) embedded Universal Flash Storage (eUFS) solution for use in next-generation mobile devices. by Julien Happich  @ eenewseurope.com:

The 512GB eUFS packs eight of Samsung’s latest 64-layer 512-gigabit (Gb) V-NAND chips together with a controller chip, doubling the density of Samsung’s previous 48-layer V-NAND-based 256GB eUFS in the same amount of space as the 256GB package. The new high-capacity eUFS enables a flagship smartphone to store approximately 130 4K Ultra HD (3840×2160) video clips of a 10-minute duration. To maximize the performance and energy efficiency of the new 512GB eUFS, Samsung has introduced a new set of proprietary technologies. The 512GB eUFS’ controller chip speeds up the mapping process for converting logical block addresses to those of physical blocks. With its sequential read and writes reaching up to 860 megabytes per second (MB/s) and 255MB/s respectively, the 512GB embedded memory enables transferring a 5GB-equivalent full HD video clip to an SSD in about six seconds, over eight times faster than a typical microSD card.

Researchers at EPFL in Switzerland have found that adding large organic compounds called guanidinium (CH6N3+) into methylammonium lead iodide perovskite solar cells can provide stable power efficiency of 19%, approaching that of silicon cells. by Nick Flaherty @ eenewseurope.com:

The lab of Mohammad Khaja Nazeeruddin at EPFL Valais Wallis, with colleagues at the University of Cordoba and the Helmholtz Institute in Berlin, has discovered that they can improve the perovskite stability, overcoming what is known as the “Goldschmidt tolerance factor limit.” This is an indicator of the stability of a perovskite crystal, which describes how compatible a particular ion is to it. An ideal Goldschmidt tolerance factor should be below or equal to 1; guanidinium’s is 1.03.

Mini DC/DC converters integrate coil

Torex Semiconductor’s XCL223 and XCL224 series of step-down converters pack an inductor and control IC in a single 2.25×1.5×0.75-mm package, simplifying board layout. Despite their miniaturization and reduced height, the synchronous converters deliver an output current of 400 mA or 700 mA. by Susan Nordyk  @ edn.com:

An operating voltage range of 2.5V to 5.5V accommodates applications that require an internally fixed output voltage of 0.8 V to 3.6 V. Output voltage is selectable in 0.05 V steps, accurate to within ±2.0%. Both the XCL223 and XCL224 series use synchronous rectification at an operating frequency of 3.0 MHz. The XCL223 converters offer PWM control, while the XCL224 converters provide PWM/PFM auto-switching control.

Hands-on with the PocketBeagle

Ken Shirriff shares his experience with a low-cost, compact Linux computer PocketBeagle:

The PocketBeagle is a tiny but powerful inexpensive key-fob-sized open source Linux computer. It has 44 digital I/O pins, 8 analog inputs, and supports multiple serial I/O protocols, making it very useful as a controller. In addition, its processor includes two 200-MHz microcontrollers that allow you to implement low-latency, real-time functions while still having the capabilities of a Linux system This article discusses my experience trying out different features of the PocketBeagle, along with some technical details.
