[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...
It's the new MEGA 2560. The Arduino MEGA USB board is compatible with most shields for the Duemilanove/Uno and has more pins, UART etc. It sports the bigger Atmega2560 compared to the previous Mega1280.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 328 - 5V/16Mhz microcontroller board is a minimal version of the Arduino by SparkFun designed for the experienced user who wants control over how connections are made to the board and a low cost. The Arduino Pro uses the same ATMega chip as the Arduino Duemilanove 328 USB Board.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...
