##BOM
- Shield Board (eagle schematic provided)
- Arduino Uno
- Chip to Program, either an ATTiny85, ATmega328P-PU, ATmega328P(TQFP)
- 16Mhz Crystal
- Capacitors for Crytsal (22 pF) x2
- 10uF Cap
- 10k Resistor (0603)
- 330 Resistor (0603)
- 4 Slide Switches
- SMD LED (1206) For a detailed list please see the BOM
##Here is what the shield looks like.

##How To Use NOTE: You can only program one board at a time.
From top to bottom, here is what each switch does.
- Switch 1 (Connection to Pin 1 of ATMega): Arduino 10 <--> Arduino Reset
- Switch 2 (Connection to Pin 3 of ATMega): Disconnected <--> Arduino TX
- Switch 3 (Conenction to Pin 2 of ATMega): Disconnected <--> Arduino RX
- Switch 4 : Arduino Reset connected to Capacitor (10uF) <--> Disconnected
For ATtiny85:
- Switches 1-3 : Does not matter
- Switch 4 : To the Left (Reset connected to Cap)
For Bootloader onto ATMega (both forms):
- Switch 1: To the left (Arduino 10)
- Switch 2/3: To the left (Disconnected)
- Switch 4: To the right (Disconnected)
For Programming onto ATMega (both forms):
- Switch 1: To the Right (Arduino Reset)
- Switch 2/3: To the Right (Rx/Tx)
- Switch 4: To the right (Disconnected)
- Note: Remove the arduino's built in mega chip to do this.
