Higher RF power, GMSK modulation and extra low power consumption make a new communication module interesting even for rough conditions.

At cars, chip-tuning usually results in a higher power of a motor. Even the new communication module (transceiver) TR72D from IQRF has passed such „chip-tuning“ of RF portion, resulting in a higher max. RF output (up to 12mW). New RF chip – Spirit1, used at TR72D also provides excellent sensitivity and GMSK modulation (Gaussian Minimum Shift Keying) with high resistance to interference. That´s why the new module is able to transfer data at much higher distance than previous types (up to 600m on a free space). This improvement has one limitation – the new module is usable with applications originally developed for previous types, but it´s not usable in one RF network simultaneously with older types (because of a different modulation).Basically the new module TR72D offers the same straightforward development of devices with a wireless communication as previous modules. The best idea about differences among particular types will give you the attached table. TR72D is a hot novelty from which we have first engineering samples. Version „DAx“ also contains built-in antenna.

Features of IQRF technology, description of the development environment and other features can be found in a record of our webinar Wireless MESH networks without programming.

Detailed information will provide you the Wago 2059-2060-2061 brochure.

20150413011804-nextion_r4_c2

Objective-oriented display solution, to reduce the GUI development difficulty and shorten the cycle.

Nextion is a Seamless Human Machine Interface (HMI) solution that provides a control and visualisation interface between a human and a process, machine, application or appliance. Nextion is mainly applied to IoT or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube.

This solution includes hardware part – a series of TFT boards and software part – Nextion editor. Nextion TFT board uses only one serial port to do communicating. Let you get rid of the wiring trouble. We notice that most engineers spend much time in application development but get unpleasant results. In this situation, Nextion editor has mass components such as button, text, progress bar, slider, instrument panel etc. to enrich your interface design. And the drag-and-drop function ensures that you spend less time in programming, which will reduce your 99% development workloads. With the help of this WYSIWYG editor, GUI designing is a piece of cake.

Michigan Micro Mote (M3) is the world’s smallest computer. How small? It’s about the size of a grain of rice. A University of Michigan’s March report can tell you that the team behind the computer have come up with a fully autonomous system that can act as a smart sensing system. “To be ‘complete,’ a computer system must have an input of data, the ability to process that data – meaning process and store it, make decisions about what to do next – and ultimately, the ability to output the data,” said David Blaauw, one of the faculty members who achieved the Michigan Micro Mote.

Hey, watch where you’re flicking. That’s a computer – [Link]

aluminum-ion-battery

by Darren Quick @ gizmag.com:

Researchers at Stanford University have created a fast-charging and long-lasting rechargeable battery that is inexpensive to produce, and which they claim could replace many of the lithium-ion and alkaline batteries powering our gadgets today. The prototype aluminum-ion battery is also safer, not bursting into flames as some of its lithium-ion brethren are wont to do.

The prototype battery features an anode made of aluminum, a cathode of graphite and an ionic liquid electrolyte, all packed within a flexible, polymer-coated pouch. And unlike lithium-ion batteries, which can short circuit and explode or catch fire when punctured, the aluminum-ion battery will actually continue working for a short while before not bursting into flames.

simple-switcher

This reference design from TI demonstrates the LM46002 SIMPLE SWITCHER® Synchronous Buck Converter and the LMZ21701 SIMPLE SWITCHER® Nano Module. The LM46002 provides a regulated 12V rail from an input of 15V to 60V. The 12V rail is then regulated down to 5V, 3.3V, and 1.8V rails using three LMZ21701 nano modules. Each rail can provide up to 1A of load current.  This modules’ wide input voltage capability and small solution size, ease of use, high efficiency and modular design was seen at APEC.

LM3481MM

TI’s PMP9476 is a non-synchronous  buck converter plus a non-sync boost controller accepting an input voltage of 3.5V to 40V, with 5V output at up to 3A of current to the load.  It features a small form factor; with PFET to replace LM3481 controller rectifier to improve efficiency and low component temperature rise; and reverse polarity protection built in. The nominal switching frequency of the design is 300kHz. The board is a 4- layer PCB with 1oz copper on all 4 layers. The design incorporates an LM3481 boost controller acts as a pre-boost stage for the LM26003 buck when start-stop occurs.

The maker movement is made up of some 135 million adults in the U.S., however, it’s more than just a U.S. movement. Maker faires that celebrate the movement have popped up in Japan, Italy, Norway, and Chile. Makers use their skills to craft items such as clothing, baked goods, jewelry, and art; contributing $29 billion to the U.S. economy annually.

From 3D printers to laser cutters—makers employ various tools to create their goods. Many gather at makerspaces where they share these resources. Makerspaces are havens for techies, artists, and entrepreneurs. Through crowdfunding, makers are able to facilitate small-scale funding for these gathering spaces.

Toshiba has added a new variant to its TX04 range of microcontrollers. The TMPM46BF10FG is targeted at IoT applications and incorporates dedicated hardware to implement a true random number generator (TRNG: SP800-90C standard) through the combination of a random entropy seed generation (ESG) circuit and Hash-DRGB created by the secure hash processor (SHA) and software program. These features offload computational overheads on the main processor and meet the standards of security required for network communications.

Based around an ARM Cortex-M4F core, with a maximum operating frequency of 120 MHz, the TMPM46BF10FG incorporates 1024 Kbyte of flash memory and 514 Kbyte SRAM required for secure communications control, four types of security circuits for network communications. The MCU also integrates an SLC NAND flash memory controller and 4- and 8-bit error correction circuitry (BCH ECC) that supports memory expansion with 1Gbit to 4Gbit SLC NAND flash memory chips.

Thin LED strip but also a powerful LED application sourced directly from 230V mains line are no problem for Wago series 2059, 2060 and 2061 terminal blocks.

Innovative series Wago 2060 now has two new familiar – smaller and bigger one. We talk about series 2059 and 2061. In result, WAGO 2059, 2060 a 2061 LED terminal blocks series create a comprehensive family of SMT connectors usable for practically any LED applications and in general – for every application, where advantages are low profile of connectors, reliable contact resistant to vibrations (spring clamp) and also aesthetical look…

Already the 2060 series showed us all main benefits of SMT LED connectors Wago 20xx. It has found its place on a market very quickly and it´s perspective for all new designs. Moreover, now we can choose from already three types:

  • 2059 – extra miniature connector, only 2.7 mm high. 160V/3A, for wires 0.14-0.34 mm2, 3mm pitch.
  • 2060 – universal miniature connector, only 4.5 mm high. 160V/9A, for wires 0.2-0.75 mm2, 4mm pitch. Also available with 8mm pitch version with max. operating voltage up to 630V. Also available a THR version with wave-solderable pins.
  • 2061 – the biggest (but still miniature) connector, only 5.6mm high. 320V/ 17.5A, for wires 0.5-1.,5mm2, 6 mm pitch. Ideal for direct connection of power supply to products (power input and output for LED drivers, powerful LED applications, …). A black version is also available.

All types are produced in 1-3 pole versions and also available are connecting links to interconnect two PCBs with each other (easy creation of long strings). Similarly, all types are suitable for automated pick-and-place assembly. Connector body is made of a made of an advanced material (glass fiber reinforced PPA) with a very wide range of operating temperatures.

Detailed information will provide you the Wago 2059-2060-2061 brochure.
