Well-proven embedded mini PC with Windows CE – BEGA220 are now available in the IP66 protection class.

Bega220 as a universal microcomputer with an OS and a 7“ touch display already found its place in many applications. Now company Bolymin launched on the market an improved version resistant to dust and water (IP66) – the BE220C module. IP66 resistance applies to a front side and a bezel, what´s in the vast majority cases fully sufficient, because in praxis the module is always installed into a target device.

BE220C maintains all features of the Bega220 series. Functionality, interfaces and pinout of a communication protocol are the same. BE220C is supplied with a cable for connection to a communication connector on a bottom side of the module and also with a USB reduction (for connection of a keyboard or a mouse). The module should be powered by a 12V/1-1,2A adapter with a 5,5/2,5 mm DC connector. Also supplied is the CD with a user manual, software development kit (SDK) and code examples.

  BE220C can be used (similarly like Bega220) for control of any devices or processes while maintaining an advantage of an easy programming in the Windows environment and compatibility with widely available software for a PC.

Detailed information will provide you the BE220C flyer and the BEGA220 user manual.

Desoldering braid makes an invaluable service at development or rework.

Everyone who´s ever tried to suck off a solder from a solder pad by means of a solder absorbing braid (wick) will probably confirm, that this tool belongs to a “must have” equipment of every professional or amateur workplace. What´s the charm of a desoldering braid? Above all in the fact, that it´s able to absorb almost all the solder from a given place, thus the most of components can be loosened very easily. Hand (pneumatic) pump surely has its place, mainly when working with bigger components, but at comparison with a desoldering braid it´s similar like if we compared a broom with a vacuum cleaner.

A quality desoldering braid is usually able to absorb a solder so thoroughly, that only a microscopic layer of a solder will remain on a PCB – as if a board was new, unused. It is very advantageous even at a hand rework of SMT components, because it´s desirable the component to lay directly on a board – not askew in a thick solder layer causing a mechanical tension and able to cause even a malfunction of a component (often at SMT capacitors).

To reach a good functionality of a desoldering wick it should be made of a fine gauge copper wires (without oil residues end similar) and it must be treated with a high quality flux. The cheapest braids usually contain only a rosin-based flux, the better ones have a synthetic flux based, which produce less fumes. Read the rest of this entry »

ethos_lite

The Ethos lite is a tiny unmanaged Ethernet switch that has 5 ports, supports 10/100mb data rates on a board measuring just 1.75″ x 1.75″ and weighing only 15 grams. One primary area where the Ethos lite stands out is in situations where weight and power are high priorities such as Unmanned Aerial Vehicles or robotics. All 5 ports are fully shielded with magnetic couplers for common mode rejection meeting Ethernet wiring specifications. This allows designers the ability to skip the large RJ45 connectors and wire directly onto connected peripherals or place the connectors in a more flexible location.

The Ethos board can accept a wide range of voltage input from 5-15V making it an ideal fit for Unmanned Systems that provide battery power. The Ethos board can also double as a 3.3V regulator providing up to 1 Amp of current. Under full load (all 5 ports actively sending data) the Ethos consumes less than 2 Watts.

Connections to the Ethos lite are provided by Molex PicoBlade headers with one for each port and an additional connector for power. As an added feature the MDIO lines to the Ethernet switch IC have been exported allowing developers access to management data registers.

Included with the Ethos lite is the main board along with 6 Molex PicoBlade cables (5 with RJ45 connectors, 1 with bare wires for power). The Ethos lite costs $250 with the ability to purchase extra Molex cables in a variety of configurations.

WiFi 802.11 b/g/n module usable immediately and with a minimum effort may be the right solution even for you.

There are many types of WiFi modules with various features on the market. For example recently described WizFi630 is literally full of functions, which take it into a class of routers. On the other hand a novelty WizFi250 has somewhat less functionality but meets all common requirements for a compact and easily applicable WiFi module suitable for a mass usage into various devices and it adds an important bonus – a very competitive price. WizFi250 provides all necessary for a simple usage – an integrated RF amplifier, antenna, low power consumption, 1MB Flash and secure protocols (WEP, WPA, WPA2PSK) and mainly easy control by simple AT commands. Thanks to its features is the WizFi 250 suitable for all common 8/16/32 bit microcontrollers.  

For the development support we also keep in stock the WizFi250-EVB development board. Detailed information will provide you the WizFi250 datasheet.

From now, it´s even more probable to find the right connector for your application in our store.

After success of so far types of connectors for memory cards and SIM cards, we add to our stock offer many other types of connectors for SIM cards, SD cards, micro SD cards, CF cards, E-SAT, DDR and other from company Attend.We realize that at a development even seaming trifles are important, other pin position etc., which decide whether a given connector is usable or not in your application. That´s why we offer you at some types (SD, micro SD, SIM, …) even several versions of a seemingly same connector. From many types we have in stock initial amounts as yet, but soon we´ll increase this count – depending on your interest.

An interesting alternative to common micro SD connectors is the type 112C-TBAR-R02 with a swiveling holder. The connector is suitable for applications, where an often exchange of SD cards is not supposed, but it is necessary to save space on a PCB or where it´s not possible to insert a memory card from a side.
Similarly interesting is the „2in1“ connector 112G-TA00-R for a micro SD and a SIM card. This connector particularly saves PCB space.

The highest communication speed UMTS/HSPA+ and an easy communication via USB make the new module ideal for M2M applications.

Fast data transmission is becoming an inseparable part of devices for automotive industry, measuring, tracking, security systems, wireless terminals (POS), mobile computers etc.

When we´re choosing a module for above mentioned segments, it´s surely worth if the module also offers somewhat so to say “extra”. In case of the UC20 module it´s true, because there´s probably no parameter, which would the UC20 not meet and when you look closer at the datasheet, you´ll also find another functions like for example 2x 15 bit AD converter and other. A big advantage of the UC20 is, that it supports a fast transmission even outside of the 3G networks thanks to a dual mode (+ Multi-band) for WCDMA but even GSM with a support of GPRS/EDGE Multi-slot Class 12. A considerable benefit are also the Windows USB drivers (Linux and Android drivers are in development).

  UC20 can air itself even with a high sensitivity and a high integrity of transferred data even in adverse conditions. For a development support, there are also available reference examples – UC20-reference design as well as UC20-Compatibility design regarding HW compatibility of UC20 with the M10 module.

All package (12x pdf) of software user guides can be downloaded on this link (11MB). Detailed information will provide you the documents UC20-Specification, UC20-Presentation and UC20 Hardware design.

For many applications can be beneficial the UC20 module on a PCB in a form of the Mini PCIe card. Also available is the UC20_EVB development board.

With a height of only 4.5 mm are new terminal blocks able to connect LED modules and LED panels aesthetically and with a maximal reliability.

There are numerous SMT connectors on the market, which are suitable for usage on LED panels but even in other applications. That´s why it´s a logic question – why just Wago 2060?

Firstly it is because of a sophisticated construction of a terminal block with a globally known and million times proven screwless spring clamp CageClampS. This clamp has an optimum pressure on a wire ideally responding to a wire diameter, i.e. the thicker wire, the bigger pressure. Also thanks to this is the max. allowed current up to 9A (!). Further, it´s possible to install solid and ferruled wires even without tools. By a simple pressing to a terminal block (for example by a screwdriver), it´s possible to insert even fine stranded flexible leads and by similar way also to disengage. Features of a clamp don´t get worse neither after multiple disengaging of a connection and they remain stable even after a long period of operation.

From other positives it´s necessary to mention a “balcony” construction of an input portion, which makes installation of wires easier and faster. Sufficiently big flat area ensures a reliable application on assembly machines (pick-n-place). And finally – an aesthetic curved shape and a white/cream color cause, that connectors are inconspicuous and they don´t disturb on a PCB.

  Terminal blocks are available in 1,2 and 3-pole version. You don’t need to be in doubt that you missed development and you still don´t know a circuit operating on 1 pole :-) – naturally the single-pole version is intended for connecting of several modules into series. A big plus is also availability of interconnecting both-sided pins enabling easy and aesthetic creation of a row (string) of several modules.

Pin spacing is 4mm and there´s also available a version with 8mm pin spacing with operating voltage of up to 600V. Connector casing is made of an advanced material (glass fibre reinforced PPA) with a very wide range of operating temperatures.

Novelty is also a newer version – Wago 2061 with up to 12A max. current. Detailed information will provide you the Wago 2060 brochure.
