SparkFun's minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader (select 'LilyPad' within the Arduino software). The Skinny is not a fully certified Arduino board. We're working with Arduino.cc towards certification. We just wanted to get this posted and moving. Future revisions will have multiple improvements. This board does not work with the 5V Arduino shields but does work nicely with our prototyping shield.

Skinny does not come with connectors populated so that you can solder in any connector or wire with any orientation you need.

We really wanted to minimize the cost of an Arduino so the USB connection has been moved off board. This board connects directly to the LilyPad USB Link (listed below). Skinny does not currently support remote reset from the Arduino Software, but we're working on it.

Skinny was designed to be... well, Skinny. We wanted the board to be low profile. The DC power jack footprint is available, but not populated. We recommend running the board with a LiPo battery for better portability.

Features:

• 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

• Schematic
