Despite a low power consumption this relay handles 5A/250VAC while maintaining a considerably long lifetime.

If we should mark an electronic component by a term “sympathic”, then the FTR-MY MY relay should be one of adepts …. Why? It´s simply chic. FTR-MY is:

  • slim (5mm), so it doesn´t take much time on a PCB (only 100 mm2)
  • relatively low profile (12mm), so it´s usable in majority of applications
  • very sensitive (110 mW), operates even at 54 mW
  • handles 5A/250VAC but thanks to bifurcated gold-plated contacts doesn´t have problems neither with small signals
  • outstands by long mechanical and electrical lifetime

In praxis it looks so, that on a small PCB space, where we´d usually fit 3 common relays, it´s possible to assemble 10 pcs FTR-MY.
Despite small dimensions FTR-MY has an isolation strength of 3000VAC. Even thanks to a low power consumption, max. operating temperature is +90°C and at the same time FTR-MY enables dense assembly without worry about overheating.
The last bonus of FTR-MY is a considerably affordable price. By its specification, this series is comparable (or even better) with series NY.

Detailed information will provide you the Fujitsu FTR-MY datasheet.
The first representative in our stock is type FTR-MYAA005D with a 5VDC coil.

Internet is “good” not only for people but also for various devices (things), what we´re experiencing on every step. And that´s only the beginning ….

Term „Internet of Things – IoT“ is known already for several years and in general it addresses connection of various devices to internet. What´s the benefit of internet connectivity for various devices, sensors and other modules? It´s quite a lot, what IoT enables, for example:

  • remote data read out, practically from any place on Earth
  • remote control
  • diagnostics, watching and early prevention of faults
  • minimizing of physical control and service intervention to a given device
  • real-time evaluation and many other

A common feature of all „IoT“ devices is, that they are uniquely identifiable. A global expansion of internet caused, that technical equipment (for example Ethernet/ serial interfaces) enabling implementation of TCP/IP Ethernet or WiFi into a target device are available for affordable prices, so it´s relatively simple and affordable to add internet connectivity into a target device. Using this connectivity we gain a possibility to use a given device in virtually any environment and any country.
Already a small, easily usable module like for example Xport is, is able to provide a TCP/IP connectivity and provides a possibility to administrate a given device through a web server.

Internet of Things should be beneficial for both – producer and also for user (or administrator) of a given device. A user is prospering from an easy data collection through a practically everywhere-available network and a producer is in many cases able to diagnose or service given device within few seconds or minutes.
One of the biggest advantages of using internet as an “interconnecting element” is a possibility of unlimited expansion of connected devices and relatively simple data processing. Many smaller but also renowned companies already today offer a software development – customized for a given IoT application.
A characteristic feature of IoT is, that generated data originate from “things”, not from human as it is so far at the majority of nowadays internet content. Direct data transfer without human intervention increases accuracy, eliminates possible mistakes and mainly – saves human work and attention.

One of many ways how to IoT enable your device is to use some of common embedded microcomputers. UDOO, Embedded Artists, BeagleBoard, Raspberry Pi, Banana Pi and many other modules provide for an affordable price a considerable computing power, wide connectivity and intelligence to a target device. Finally, a display with a touch panel in connection with such a microcomputer usually creates a user friendly (HMI) interfaces. As a result, such a device is in majority of cases much more attractive for an end user. A brief comparison of some popular embedded microcomputers can be found here.
The newest term on this field is the „Internet of Everything“, i.e. internet connecting people, processes, data and things. Perhaps only the nearest future will show a real status, which can be influenced even by you – by a design of your devices.

Minimal power consumption, slim design and a big amount of available versions with multi-color backlight – these are some benefits of the EADOG series displays.

EADOG series is familiar to many of you and probably it´s your favorite one from these main reasons:

  • displays are unusually flat (thin)
  • the have a very low power consumption of 100-s uA (without backlight)
  • wide possibilities of backlight, monochrome and also RGB
  • some types are well legible even without backlight
  • simple communication through 4/8 bit or SPI interface and newly even I2C

So far, types with up to 128x64px or 3×16 characters were available. The most recent additions to the EADOG family are bigger types with resolution of 160x104px (EADOGXL160), 240x64px (EADOGM240), 240x128px (EADOGXL240) and 4×20 characters (EADOGM204) and appropriate backlight modules EALED66x40, EALED94x40 and EALED94x67. Also these new types maintain a low profile – only 5.8 or 6.5mm with backlighting. A positivity is that even these new types are based on standard LCD controllers.

A guide at a choice of a suitable combination of display +backlight will provide you the application described in our article – Start with the EA DOG displays for free.

Detailed information will provide you the datasheets at particular types.

New graphic chips supporting capacitive touch screens – FT801 with the “EVE” technology from company FTDI bring a simple usage even for these perspective displays.

FT801 brings together advantages of the „Embedded Video Engine“ (EVE) concept and advantages of capacitive displays like easy control, interactivity and usually a higher brightness and overall vividness of these displays.

New chip FT801 is functionally practically the same as the initial EVE chip – FT800. It supports display, audio and touch interface with a capacitive touch screen via an I²C interface connected to a standard touch controller.FT801 has multi-touch capabilities enabling 5 independent touch points to be simultaneously determined (so called Extended mode). This facilitates the deployment of human machine interfaces (HMIs) usable by several people at once, or where a variety of complex hand gestures can be detected. The IC’s sophisticated hardware engine has the ability to recognize touch tags and track touch movement – delivering notification of up to 255 touch tags.

The capacitive touch panel module (CTPM) asserts an interrupt when a touch is detected, signalling the FT801 to read the touch data via I2C. Additionally the FT801  supports a Compatibility touch mode, where existing FT800 application code can be run with single touch events detected.

The device is packaged in the same 48 pin QFN footprint as the FT800 and enables to use practically the same display design as at FT800, including 3 in1 functionality (Display, Audio and Touch) and 1/16th pixel resolution. A 12MHz crystal oscillator with PLL can deliver a 48MHz or 36MHz system clock.

Detailed description can be found in the FT801 datasheet.

High power of the UDOO “asks” for usage. One of many occasions to make it is to use various available periphery thus gaining a truly universal platform.

Favorite powerful embedded SBC called UDOO (S975-G000-2100-C2) already found many fans. Maybe also because of its compatibility with the Arduino Due platform (hardware and software) and mainly, it´s possible to connect it with various accessories. Thanks to a wide range of interfaces (USB, Ethernet, bluetooth, WiFi, …) is a connection of periphery flawless, what´s also a case of the 5MPx camera (autofocus).

Despite miniature dimensions this camera provides very decent resolution and speed – for example VGA (640×480) @90fps or 1080p @30fps, or QSXGA (2592×1944) @15fps. Also beneficial is recording of a video in a full 70°field of view (FOV).For a practical usage and application development with UDOO also serves the „Starter kit EU” containing an adapter for the third USB, RTC battery holder, HDMI cable with the UDOO logo, USB/ Micro USB Type B cable, SATA power supply cable, power supply adapter and an 8 GB micro SD card.

Perhaps the biggest “attraction” is the spacious 7“ display KIT LCD 7”–Touch 800×480 px RGB with a capacitive touch panel. By connecting of this display with the UDOO microcomputer, we get a ready-made platform usable to control various processes, with a power, which easily suits to majority of applications. Detailed information about the UDOO can be found in our article: Do you want a microcomputer which will „handle everything“?.

New „hardwired“ TCP/IP chip from company Wiznet resists attacks, it´s fast and consumes only a minimum energy and host MCU resources.

TCP/IP solutions from company Wiznet are known by its resistance resulting already from their principle . all the solution is hardware-based, thus it´s not possible to change a basic functionality of a device (flooding, spoofing, …). W5500 outstands by its “modesty” – it only requires a few GPIO pins of a host MCU – thanks to a high speed SPI interface (up to 80 MHz) and it also has a very low power consumption. A result of a small consumption is, that the chip heats up to approx. 40´C at a common operation, in contrast to other similar chips, which usually have 60-70´C at operation. This naturally means a higher reliability, possibility of a more dense placing of components and elimination of problems with overheating of a device built-in into a small enclosure.

Energy saving is also enhanced by Power Down and Wake-on-LAN (over UDP) modes. Single 3,3V are enough for power supply, while inputs are 5V tolerant. Status is indicated on LED outputs (full/half duplex, link speed, active) and the chip contains a built-in OS Linux (kernel 2.4.xx, 2.6.xx, 3.1,xx) & RTOS driver.

In our offer can be found the W5500 chip itself W5500-EVB evaluation board, as well as a ready-made module WIZ550S2E-TTL or WIZ550io. Examples of a real usage of Wiznet chips can be found in the document Wiznet application reference.
