[Replaced by our 30mm nickel plated brass standoffs 4-pack]. These hexagonal male-female aluminium standoffs keep parts spaced 1.25" (32mm) apart and are great for building a multi-level robot chassis. This 4-pack of standoffs includes 4 aluminium nuts for securing the top of the standoff to your project. More details...

*** Clearance *** Arduino Duemilanove USB Board is the successor to the Diecimila and is a great introductory microcontroller board with automatic power selection (USB or external), powerfull Atmel ATMega328 processor, a bootloader and big user community. More details...

** Replaced by Mega2560 ** It's the MEGA, its more. Basically the Arduino MEGA is like the Duemilanove but with more. More pins, UARTs, PWMs, Flash memory. The Arduino MEGA USB board is compatible with most shields for the Duemilanove and sports the bigger Atmel Atmega1280. More details...

Just like the Duemilanove only smaller. The Arduino Nano microcontroller is very similar to the Duemilanove but comes in a considerably smaller package and is suitable for mounting on a breadboard. It has the same Atmega328 chip, connects with a USB cable and has all the same input/output. More details...

The Arduino Pro Mini 328 3.3V/8MHz is miniature Arduino microcontroller board by SparkFun Electronics. At a tiny 18mm x 33mm and 0.8mm high this board uses the same ATmega328 chip as the Arduino Uno but is much smaller, lighter and cheaper. More details...

Designed to allow an Arduino Mini, Stamp, Pro Mini to be connected to your computer with a USB cable. Can also be used with any other serial device as a general serial-USB adaptor. More details...

This a unique shield for the Arduino platform. This board mates directly with the Arduino USB board and allows the Arduino to wireless communicate over a modified ZigBee protocol using the popular XBee module from Maxstream. This shield does not include an XBee module. Any XBee module will work with the shield. More details...

Xbee wireless communication can be easily added to an Arduino Duemilanove USB board or Mega with this shield and on-board Digi (formally MaxStream) Zigbee XBee module capable of 30m indoors or 90m outdoors. More details...

The very popular CMPS03 is a great little compass module designed for specifically for robotics use. It detects the earths magnetic field and outputs a direction reading with an accuracy of 3-4 degrees via either an I2C interface or a PWM signal. ** See the new CMPS10 ** More details...
