Prototyping Board

All the standard components have been packed together as tightly as possible on this board, leaving room for a prototyping area of solder points (like perf board). Good if you only need a couple extra parts for a prototype. The trade-off is that this board doesn't have a serial or USB port. You need to program it with an external programmer.

Eagle files (schematic and board layout), single-side variant of this board (only 4 jumper wires, no connector moved, uses Eagle SCH file from original)

Parts List

Digikey parts from Tom Igoe

Note: some part numbers (e.g. C4) are unused because this schematic was made by deleting pieces of the Arduino serial schematic.
