- Active-Robots Range of Sparkfun Products

Sensors (103 products) - Accelerometers, biometrics, finger print scanners and heart monitors. A capacitive interface board. Flex/Force sensors. Humiditiy Sensors. Magnetic including swipe card readers and writers. Infrared sensors, lighting and imaging sensors. Magneto sensors. Pressure sensors, proximity and temperature sensors.

Lithium Batteries (8 products) -These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cell outputs a nominal 3.7V at 1100mAh!

Linear Actuators (4 products) - Great linear actuator from Miga Motors. The NM70 is a very small electric actuator that utilizes Shape Memory Alloy (SMA) with a 4.0mm stroke when exposed to 3.5V and 410mA. The amazing thing is this 1.1g device can move up to 70g!

Step-Up & Step-Down Converters (4 Products) -The is a wonderfully simple 5V power source. This unit uses a single AA battery and generates 5V using a DC to DC step up circuit. A jumper is provided on the unit to disconnect power and includes a terminated (right is red) connector. Perfect for all those 5V applications that need to be small, and run on less than 100mA.

Mini Breadboards & PSUs (5 Products) - Very small breadboards with 170 tie points available in a variety of colours ideal for prototyping. Also a choice of two very simple regulated breadboard power supplies.

Opto-Isolator Breakout - This is a board designed for opto-isolation. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC.

Bluetooth Modem BlueSMiRF Gold - The BlueSMiRF is the latest Bluetooth® wireless serial cable replacement from SparkFun Electronics! These modems work as a serial (RX/TX) pipe. Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target. We've tested these units successfully over open air at 350ft (106m)!

Motor Driver 1A Dual - The TB6612FNG from Pololu is a great dual motor driver that is perfect for interfacing small DC motors such as the micro metal gearmotors to a microcontroller.
