SparkFun: COM-00102
Description: Simple SPDT slide switch. Rated at 30V/200mA. The pins have .1″ spacing – fits great into a breadboard! Use it as a power switch or general control switch.

SparkFun: COM-09609
Description: This is a simple SPDT slide switch – great for use as an ON/OFF button, or just as a general control switch. The pins are spaced by 0.1″, however they are incredibly thin making breadboard use not recommended. The switch is rated for 0.3A at 50VDC.
This switch is just a bit smaller than our popular SPDT Mini Power Switch, but uses the same pin spacing. Being smaller takes up less PCB space (good!), but it does make it a bit harder to hit and flip easily.

Description: The STA540 from STMicro is a 4-channel, class AB audio amplifier designed for high quality sound applications. The four independent channels makes this amplifier a great choice for a number of projects, with needs ranging from four speakers stereo (F/R) to two-speaker bridge solutions. The chip accepts a voltage supply ranging from 8 to 22VDC and has very high output power capability.
This chip comes in a staggered-lead Multiwatt-15 package. While our breakout board for the L298N isn’t designed for it specifically, it will breakout out all pins of the STA540 to a more standard single row of 0.1″ pitch headers. Also, keep an eye out for some upcoming amplifier products based on this chip!
It works great with the 6400BG Heatsink!

SparkFun: COM-07950
Description: This is a small 12mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interfaces.
Each speaker is PTH solderable and requires an operating voltage of 3.5-5V with a mean current of 35mA max. These speakers also have a typical sound output of 95 dBA and a coil resistance of 42 ±6.3 ohms. Many people call this a buzzer but it is not. The piezo element requires a square wave (common from most microcontrollers) to produce a tone.

SparkFun: SEN-00245
Description: This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it – allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner stone of many data-logging and temperature control projects.

SparkFun: SEN-09088
Description: This is a very small light sensor. A photocell changes (also called a photodetector, photo resistor, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).

SparkFun: SEN-00241
Description: Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.

SparkFun: ROB-10551
Description: These small steppers are a great way to get things moving, especially when positioning and repeatability is a concern.
When using a current limiting driver such as the Easydriver or Big Easydriver, a 12 volt power supply can be used as long as you adjust the current level to 400mA or less. If using a non current limited driver (like a L293D or an H-bridge) you will need to lower your input voltage to keep the motor current below 400mA.
This is a Bipolar motor.
