The RBBB from Modern Device Company is a wonderful little Arduino clone. If you have a Arduino project requiring a small footprint or an inexpensive dedicated board, this is a great solution.
I discovered the RBBB while looking for a cheaper alternative to the official Arduino board I used in developing my Northern Lights Indicator. On sale, buying 5 kits, these came out to about $9 each. That is a huge savings over the $35 Arduino Diecimila.
Step 1: The Kit
2 10k resistors (Brown, Black, Orange)
2 .1ufd ceramic capacitors
2 47 ufd electrolytic capacitors
1 voltage regulator
1 3mm LED
1 Atmega168 preprogrammed with bootloader
1 16 MHZ ceramic resonator
male header pins
6 right-angle male-header pins
1 momentary switch
1 28 pin IC socket
