Name:
Electric Imp Shield DEV-11401
Description:
If you aren't familiar with the Electric Imp, it essentially provides an easy, integrated way to connect almost any hardware device both to other devices and to internet services. It's more than just a WiFi card, or even a WiFi module with processing built in - it's an integrated platform that deals with the drudgery of connectivity, allowing you to concentrate on the application instead of the mechanics. Of course, if you're developing for it you'll need a way to get in there and poke around. The Electric Imp Shield allows you to connect your Arduino project to the internet through your home WiFi network. This way, your Arduino can take advantage of the Imp Cloud service and connect to HTTP APIs.
The Shield connects one of the imp's UARTs (Imp pins 5 and 7) to either the Arduino hardware UART or a software serial on pins 8 and 9. It defaults to the software serial, but there are jumpers on the bottom side to set it to the hardware serial. A couple imp pins (8 & 9) are also connected to LEDs. They can be disconnected via jumpers on the bottom, if you'd like.
Because the Electric Imp can draw up to 400mA on the 3.3V line, this shield has its own voltage regulator which is fed from the 5V Arduino line. Most Arduino compatible boards should be able to handle this amount of draw but beware that some clones that use less robust VREGs could see trouble.

Name:
Sparkfun Pegelwandler BOB-08745
Description:
If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. This level converter also works with 2.8V and 1.8V devices. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side. Two inputs and two outputs are provided for each side.
Bread board friendly! Can be used with normal serial, I2C, SPI, and any other digital signal. Does not work with an analog signal.
The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the 'HV' pin, low voltage (2.8V for example) to 'LV', and ground from the system to the 'GND' pin.
Pins are labeled as Inputs and Outputs. These are relative to the board. A digital one going into the RXI pin on the 5V side will show up on the RXO pin on the 3.3V side as 3.3V. A digital one going into the TXI pin on the 3.3V side will show up on the TXO pin on the 5V side as 5V.

Name:
NeoPixel Stick
Description:
Make your own little LED strip arrangement with this stick of NeoPixel LEDs. We crammed 8 of the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC (4-7V works) and you're ready to rock.
The LEDs are 'chainable' by connecting the output of one stick into the input of another - see the photo above. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Our wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.
Comes as a single stick with 8 individually addressable RGB LEDs assembled and tested.

RF Link Transmitter - 434MHz WRL-10534
Description:
These wireless transmitters work with our 434MHz receivers. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair.
Note: These modules are indiscriminate and will receive a fair amount of noise. Both the transmitter and receiver work at common frequencies and don't have IDs. Therefore, a method of filtering this noise and pairing transmitter and receiver will be necessary. The example code below shows such an example for basic operation. Please refer to the example code and links below for ways to accomplish a robust wireless data link.
Features:
434 MHz
500ft range (given perfect conditions)
4800bps data rate
5V supply voltage

Name:
ePIR Bewegungsmelder
Description:
Zilog's ePIR is a fully functional motion-detecting single-board computer (SBC). Combined on this board are a Z8 Encore! XP MCU, and a Murata passive infrared (PIR) sensor, which is shielded by a Fresnel lens. Taking advantage of the processing capabilities of the Z8 MCU, the ePIR uses a powerful new statistical processing method to provide exceptional motion detection performance.
The ePIR provides two interface modes: a simple hardware interface and more advanced serial method. If you're using the hardware interface, the motion detect (MD) pin will go low when motion is detected. In serial mode, the ePIR is read and configured using the defined set of commands - all sent asynchronously at 9600 baud (8-N-1).
The physcial interface of the ePIR is an 8-pin, 0.1" pitch male header.
Features:
Complete, fully functional motion detection SBC including low profile Fresnel lens
Advanced software based motion detection algorithms provide superior sensitivity and stability
2.7-3.6VDC operating voltage
Typical current draw: 8.9mA
Wide 5 x 5m, 60 degree detection pattern
