UDOO as one of the most powerful embedded PC (SOM) of this date breaks borders in the price/ performance ratio.
There are several microcomputers on the market, which usually support OS Linux, Android or Windows. Their usage is so to say unlimited – from simpler devices, where we´ll use mainly a ready-made connectivity (USB, Ethernet, bluetooth, WiFi, …) to more sophisticated applications in combination with TFT LCD and a powerful graphics, video, etc. Each type has its advantages (Voipac, Embedded artists, Beagle board, Friendly ARM, Raspberry Pi, …) and one of the most surprising modules is surely the microcomputer UDOO. UDOO is a powerful single board embedded PC based on a powerful Freescale i.MX6 chip and it´s available in Dual or Quad core version.
In our offer can be found the more powerful Quad version (S975-G000-2100-C2, 1GHz), which is roughly 4x more powerful than for example Raspberry Pi. Power of this microcomputer is already really respectable and it manages various 3D visualizations, videos and (real time) communication through various interfaces. Interfaces – it´s the field where the UDOO excels, because it provides on one board interfaces like Gbit Ethernet, 4x USB, HDMI, WiFi, Touch, 76 GPIO, SATA, camera, microSD,… A big advantage is a full compatibility with an Arduino Mega 2560 platform (hardware and software)..
Functionality of the UDOO microcomputer is very wide and a detailed description can´t be summarized into a short article. The best overview of features and possibilities of this module will give you the attached video as well as basic UDOO user manual.

We bring you basic useful accessory of every development and testing workplace – measuring and testing leads in the best available quality.
Whether you measure daily or only sometimes, probably you know, how significantly helpful various accessories can be. Or otherwise – how much time can consume unreliable measuring cables or other accessories, when after a long investigation for a mistake in a design you´ll find, that everything is OK, only a measuring cable had a bad contact …
For everyone who has a will and time to assemble measuring tools we have measuring tips, clips, bananas and other accessories from company SKS (Hirschmann-SKS). For those of you, who better prefer ready-made, professionally made measuring cables, we have an elegant solution in a form of the cables themselves, as well as measuring sets. Such cables and sets are especially suitable for professional workplaces and for a mass usage in assembly and testing.
Company SKS is a long time focused for measuring accessories and its products under a mark SKS-Hirschmann are known by their quality and ergonomics. From the wide production portfolio of SKS can be found in our store for example cables with a banana and a socket for a header MALN series), safety measuring leads (MALSW series), measuring leads with bananas on both sides (MLN), measuring leads with measuring tips, as well as measuring sets – PL2600 or PMS series. All measuring leads are highly flexible and with a thick insulation.
For workplaces with a high risk of damage of measuring leads from for example a hot soldering tip or other heat source are an ideal accessory silicone testing leads series MLS SIL. A „complementary” but very valued feature of silicone testing leads is also their extreme flexibility resulting in a very comfortable work. These leads we´re able to provide you upon order. Detailed information about measuring and testing equipment can be found in the Hirschmann SKS catalogue.

Beauty in simplicity – adjustable bimetal thermostat operates independently from a power supply.
Thermal comfort is, when a temperature in a house is 21-24 °C and a relative humidity is …. No, sorry, your device can withstand much more. At least 0 to 60°C or much more. If you have a device, where you need to guide the temperature, then DIN-rail thermostats are the simplest usable solution. Series 7T from company Finder offers a possibility to use such thermostats to control heating, cooling (fans) or their combination…
Besides purely industrial applications, these thermostats can also be used to control temperature in buildings or garages – for example as a frost protection. In our stock can be found five types, mainly with a range of 0 to +60°C. Available are 2 basic series – 7T81 and 7T91. 7T81 is a narrower, only 17.5 mm wide series. Series 7T91 is wider, with a more perforated enclosure, i.e. there´s an assumption of somewhat quicker reaction to temperature changes.
Orientation among types is simple. Types with a suffix …23xx are intended for switching of cooling (blue adjustable knob), i.e. after reaching a set temperature a bimetal contact switches on. Here belong for example types 7T.81.0.000.2303 and 7T.91.0.000.2303.
Types with a suffix …24xx are intended for switching of heating (red adjustable knob), i.e. after reaching a set temperature, a contact switches off. Here belong for example types 7T.81.0.000.2403 and 7T.91.0.000.2403. However in the 7T series can also be found types usable in both ways, for example 7T.91.0.000.2004 (range +5 to +60°C).

Thanks to a 15-36V output voltage, it can be connected to almost every LED module and a stable output current of 1050 mA will take care for a reliable operation.
In fact, majority of features of a new a new LED driver (power supply) – LT40-36/1050 WP (1894661) were mentioned in a subject and a preface of this article. But not to be that brief, we can add, that the new LED driver features the same good properties like its familiar descried in the article – Friwo drivers not only drive your LEDs but even control them …. From the basic types it differs mainly by a water-tight design – by encapsulation in a resin, that´s why it also withstands operation in a humid or dusty environment. This version doesn´t have an external input, thus it operates only as “standalone”, in a “constant current, limited voltage” mode. Output voltage 15-36V means, that the LED driver should only supply such a module, whose forward voltage (Vf)at a given current is 15-36V, what in praxis means approx. 6-11 (12) white LEDs in series.
That´s why LT40-36/1050 operates as a power supply, whose open voltage (without a load) is 36V. This voltage remains constant up to 1000 mA current drawing and then the voltage drops down to 15V when a current reaches 1050 mA. This ensures a constant current, i.e. if we for example connect a LED module with Vf=24V, the driver will source 1050 mA current (at 24V). LT40-36/1050WP shouldn´t be used to supply modules with a Vf lower than 15V. In such case, the types handling lower voltages are suitable, for example LT10-16/700 or LT20-28/700. If we wish to reach a maximum power from a given LED driver, it´s naturally beneficial to use a LED module with a Vf on an upper level of an output voltage of a given LED driver (33-36V in this case).
Detailed information will provide you the LT series overview and datasheets at particular types.

VFD Moduar Clock IV-4 6-digit by akafugu.jp:
This new shield design for the VFD Modular Clock is a variant of the original IV-4 shield, but with 6 digits. IV-4 tubes are Russian 16-segment VFD tubes, and can display numerals and the letters A-Z.
We’ve also designed a completely new enclosure for the IV-4 6-digit shield. It uses 2mm semi-transparent blue acrylic, and is designed to give a low-profile rounded appearance.
Creating a 6-digit IV-4 shield without redesigning the base board presented a unique challenge: The HV5812 driver used to drive the VFD tubes has 20 channels. IV-4 tubes are 16 segment displays, 20 – 16 = 4, so in other words the HV5812 driver can only support 4 IV-4 tubes.

Even in enclosures can be found a tablet – Hammond 1599 - [Link]
Crystals and crystals oscillators from German company Jauch belong to the best what´s available on the market.
If we need an exact frequency, we usually reach for crystals or crystal oscillators. If we want a stable function in a wide temperature range and in various circuits, we reach for products of a renowned producer … Crystals belong to components which we usually choose by a frequency and package. That´s sufficient in the most of cases, but less known and less compared are many other qualitative parameters (which even don´t have to be in the datasheet), which depend mainly on the production technology and from a quality of a crystal itself. Quality (Q), low phase noise, stability of oscillations, low sensitivity to mechanical vibrations and other factors have influence on the final device and its functionality in less favorable conditions in praxis (temperature, load, drive level, aging, …).
Crystals and crystal oscillators from German company Jauch Jauch belong to a top and they´re price affordable at the same time, that´s in our portfolio in this segment can be found only these quality components with guaranteed specification. Production portfolio of company Jauch is very wide, from common crystals in a HC49/U package to miniature SMT versions. Popular and often more beneficial are the ready-made crystals oscillators, which have a built-in electronics of an oscillator and provide directly an output signal of a desired frequency (usually HCMOS). In the Jauch portfolio can also be found voltage controlled oscillators – VCO and also extremely stable temperature compensated crystal oscillators – TCXO. The best insight into basic series will give you the Jauch product overview.
