“Skinny” Arduino compatible

Sparkfun’s intros their own iteration of the Arduino board –

Skinny is the first SparkFun hack into the Arduino realm. It’s not perfect, but we think you’ll like this new derivative. It’s 3.3V, runs on LiPo batteries, low-cost, low-profile, and sexy red. Which is actually one of the reasons why it cannot be a certified Arduino board (Arduino boards have to be blue).

• ATmega168V running at 8MHz internal oscillator
• Low-voltage board needs no interfacing circuitry to popular 3.3V devices and modules (GPS, Accelerometers, sensors, etc)
• USB connection off board
• 3.3V regulator
• DC input 3.3V up to 12V
• Resettable fuse prevents damage to board in case of short
• Power select switch acts as on/off switch

Could come in handy for projects lacking enclosure depth. They recommend using a Lilypad USB link for programming – Skinny
