Name: Pololu DRV8825 Schrittmotortreiber
Description: This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the driver’s key features: Simple step and direction control interface Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) 45 V maximum supply voltage Built-in regulator (no external logic voltage supply needed) Can interface directly with 3.3 V and 5 V systems Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout Short-to-ground and shorted-load protection 4-layer, 2 oz copper PCB for improved heat dissipation Exposed solderable ground pad below the driver IC on the bottom of the PCB Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information): http://www.pololu.com/catalog/product/2133

Name: Analog/Digital MUX Breakout BOB-09056
Description: Mit Hilfe dieses Boards lassen sich 16 analoge Signale auf einen ADC-Port eines Controller schalten. Es werden nur 4 digitale Pins des Controllers zur Auswahl eines der 16 Kanäle benötigt. Als Multiplexer kommt der CD74HC4067 zum Einsatz. This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip can be used to connect 16 analog sources (like sensors) to 5 pins on a microcontroller. 4 of the pins must be digital pins, 1 pin must be an analog to digital conversion pin. This allows 16 sensors to operate on only 5 pins of a micro! This is a great way to connect a lot of sensors to a few pins. You can also run the mux/demux the other direction. One serial stream connected to the SIG pin can be piped to multiple outputs. The mux/demux also works with digital signals (like serial, I2C, SPI). This means you can hook up multiple serial devices (like a GPS TX pin, and a XBee DOUT pin) to one RX pin on a microcontroller. The IC can control analog voltages that vary across the voltage supply range. The bidirectional switches allow any analog or digital input to be used as an output and vice-versa with a "Break-Before-Make" switching of 6ns at 4.5V. In addition, the switches have low "on" resistances and low "off" leakages. Includes and enable control which when high will disable all switches to their "off" state. Features: ON Resistance 70Ohms @ 4.5Vcc and 60Ohms @ 6VCC 2V to 6V operation Wide operating temperature -55C to 125C

Name: Solarzelle 24 x 33mm
Description: Monokristalline Solarzelle mit einer Spannung von 4,5V, dabei ist ein maximaler Strom von 18mA möglich. Our SCC2433-B solar cell is a monocrystalline cell offering 4.5V (open circuit) and 18mA (short circuit) in a 24x33mm package. What really makes this solar cell stand out is the circuit board on the back! It lets you assemble the simple "Miller Solarengine" which lets you pulse-power devices that would usually be impossible to power!

Name: XBee ZB ZigBee (Series 2) - PCB Antenne
Description: This is the XBee XB24-Z7CIT-004 module from Digi. Series 2 improves on the power output and data protocol. Series 2 modules allow you to create complex mesh networks based on the XBee ZB ZigBee mesh firmware. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported. These are essentially the same hardware as the older Series 2.5, but have updated firmware. They will work with Series 2.5 modules if you update the firmware through X-CTU. Note: If you are looking for a simple point-to-point configuration, you might want to try the Series 1 instead. The Series 2 requires considerable setup and configuration. We highly recommend Building Wireless Sensor Networks as a guide for setting up mesh networks. Note: Series 1 and Series 2 XBee modules have the same pin-out. However, Series 1 modules cannot communicate with Series 2 modules. Features: 3.3V @ 40mA 250kbps Max data rate 2mW output (+3dBm) 400ft (120m) range Built-in antenna Fully FCC certified 6 10-bit ADC input pins 8 digital IO pins 128-bit encryption Local or over-air configuration AT or API command set

Name: Sparkfun XBee Explorer USB WRL-08687
Description: This is a simple to use, USB to serial base unit for the XBee line. This unit works with all XBee modules including the Series 1 and Series 2.5, standard and Pro version. Plug the unit into the XBee Explorer, attach a mini USB cable, and you will have direct access to the serial and programming pins on the XBee unit. You get the red board only. XBee modules and USB cable sold below. Note: As of August 2010, all new boards now include a MIC5219 voltage regulator which is good for 500mA. Note: A pull-up on DIN is required for this board to work properly. Thankfully, Series 1 and Series 2 XBee modules have their internal pull-up enabled by default. You will need to manually enable the pull-up on the 900MHz series. http://www.instructables.com/id/Changing-Xbee-Baud-Rates/ https://www.sparkfun.com/pages/xbee_guide

Name: 3v to 5v Bistable Latching Relay
Description: Latching relays keep their switch contact direction without power, this makes them very suitable for low power situations such as batteries or where permanent power is undesired. The best way to imagine a latching relay is a light switch, you briefly push it to turn on, it remains that way with no power until you push it to turn off. Normal relays require a continuous voltage to keep the contacts closed, bistable versions do not. Keeps contacts set either on/off without requiring power (means much lower power consumption) Twin 3v DC coils are buffered by driver transistors (requires very little current to drive the coils, makes it suitable for micro-controller or TTL control) Can be used at up to 5v (as the contacts require only a brief pulse, they will tolerate 5v) Very high quality Shrack relay (means long life and reliability) SPDT relay (sometimes called single pole change over) 16Amp switching at up to 250v AC (switch high current AC or DC loads) Features: Gold plated finish (Protection against oxidization means your device will outlast normal HASL boards) Comes as a complete "self solder" kit of parts Easy large pads to solder connections to Easy to add a standard header connector if desired We can prebuild on orders over 10, there will be a cost and time associated with this, please phone or email to discuss Made in the UK Technical data: Dimensions: 35.5 mm x 29.4 mm x 19.4 mm Connections: are on standard 0.1"/2.54mm spaced holes (left to right as in picture, zoom shows in better detail). You connect PWR and GND to your power source (eg battery) and then briefly (between 1/10th and 1/2 a second is recommended) put a voltage between 2.5 and 12v into either the SET and RESET pins to flip the relays internal 16A switched contacts in either direction. After the pulse the relay will remain in that position until a pulse on the other pin flips it back. 1 - SET - Pulsed input (from a PC/micro/TTL etc) 3v to 5v 2 - RESET - Pulsed input (from a PC/micro/TTL etc) 3v to 5v 3 - GND - Ground or minus on a battery 4 - PWR - 3 to 5v power or positive on a battery N.B. - When using voltages over 3v never hold SET or RESET for longer than 1/2 second
