Development Modules Development modules are slightly larger than the breakout modules but offer access to all the FT-X device pins. The modules have a USB Mini-B connector and 0.1” pitch DIP pin for connecting the interface signals. Modules with a part number ending XA are 0.3” wide and those ending XE are 0.6” wide. Available modules: UMFT201XA – FT201XQ based USB to I2C, 0.3” wide module UMFT220XA – FT220XQ based USB to Enhanced 4-Bit SPI / FT1248, 0.3” wide module UMFT221XA – FT221XQ based USB to Enhanced 8-Bit SPI / FT1248, 0.3” wide module UMFT230XA – FT230XQ based USB to basic UART, 0.3” wide module UMFT231XA – FT231XQ based USB to full handshake UART, 0.3” wide module UMFT240XA – FT240XQ based USB to 8 – bit FIFO, 0.3” wide module

Arduino Tutorial - Lesson 5 We've done a lot so far, blinking lights, printing messages...all of that stuff is output: signals coming from the Arduino. The next step is to start playing with input, with the Arduino responding to outside events. In this lesson we will begin with the most basic kind of input, a push-button switch! You're probably familiar with switches, there's tons of them in your house.

Thermoelectric effect The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa. A thermoelectric device creates voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, it creates a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side. This effect can be used to generate electricity, measure temperature or change the temperature of objects.

Baxi Ecogen Our award-winning domestic micro-CHP boiler, the Baxi Ecogen, generates heat and electricity at the same time. With the electricity being generated close to where it will be used, the system results in fewer carbon emissions. Not only does the Baxi Ecogen help to reduce homeowner bills, electricity that doesn't get used can even be sold back to the local grid. Read the case study below to see how the Baxi Ecogen can help you Link and Scottish gas team up on Baxi Ecogen trial Baxi are honoured to have received The Queen's Award for Enterprise in Innovation 2012. This achievement is thanks to our work on Baxi Ecogen dual energy systems, which have led the way in advancing innovative design and environmental conservation throughout the industry, using micro-CHP technology.

Flexible electronics An Olympus Stylus camera without the case, showing the flex circuit assembly. Tightly assembled electronic packages, where electrical connections are required in 3 axes, such as cameras (static application).Electrical connections where the assembly is required to flex during its normal use, such as folding cell phones (dynamic application).Electrical connections between sub-assemblies to replace wire harnesses, which are heavier and bulkier, such as in cars, rockets and satellites.Electrical connections where board thickness or space constraints are driving factors. Applications[edit] Flex circuits are often used as connectors in various applications where flexibility, space savings, or production constraints limit the serviceability of rigid circuit boards or hand wiring. A common application of flex circuits is in computer keyboards; most keyboards use flex circuits for the switch matrix.

Beginners Guide Beginners Guide to Electronics by Martin T. Pickering Last updated on November 23, 2008 ntrolling a stepper motor via a USB port using visual basic Although Stepper-Bee comes with it's own software (AutoStep) to allow the beginner to start using it in home automation projects very quickly, it also comes with a DLL interface to allow the intermediate and advanced user to write their own programs for it. The DLL provides a general purpose interface that greatly simplifies the task of writing programs for a USB device. It can be tricky manipulating the USB comms into sending and receiving messages to and from a device which can easily be plugged and unplugged at any time. The DLL eliminates all of these headaches by simplifying the task into a few library functions.

Researchers Create Flexible Memory Device After flexible displays, the memory chip is the latest electronic component to get twisted and bent. Researchers at the National Institute of Standards and Technology have developed a flexible memory device that they say is inexpensive and can be easily manufactured. “We have fabricated a lightweight memory device,” says Nadine Gergel-Hackett, one of the researchers on the project, “that uses transparencies seen in overhead projectors as the material for its flexible sheet.” Flexible components are a promising new area for electronics makers who envision using them for bendable, flexible, rollable, or merely curved devices that contain electronic circuits.
