YABBAS – Yet Another Bare Bones Arduino

This Instruct able will demonstrate the building of a bare bones (and really inexpensive… less than $5) Arduino compatible module that can be put together on a small piece of strip board and can be used either on a breadboard or independently.
The following links / similar projects were used as inspiration:
The schematic is based off of the Arduino Pro Mini (http://arduino.cc/en/Main/ArduinoBoardProMini) and only differs in a few minor (optional) ways:
YABBAS – Yet Another Bare Bones Arduino
1. This design uses a more powerful voltage regulator
2. This design uses a more precise crystal (instead of ceramic resonator)
3. This design ditches the reset button (do you really need it?)
4. This design uses a 1k (instead of 10k) resistor for the power indicator LED
Prerequisites / Tools Required:
* Soldering Iron with fine tip
* Solder (fine) & Flux
* Utility Knife
* Mini needle-nose pliers (optional, but useful)
* Multi meter (or volt meter)
* An existing Arduino, or any other AVR programmer (needed to upload the boot loader)
* A USB-to-Serial TTL adapter (used to upload programs after the boot loader is in place)
