I needed to be able to use serial before it got level shifted on the VH module. A lot of the parallax and other devices i have use 5v ttl and that means that i can't plug them directly into the Von Hippel. The other thing was i wanted a way to program my ATMega chips and perhaps put some PWM ports directly on the module.

So i made a Bug Module. Take a look at the video of the first Homebrew Bug Module

It includes the following:
- 2x PWM ports
- 5v TTL serial
- 4x LED's connected to 0->3 GPIO ports
- 10 Pin ISP connector for programming AVR's
- Bread board for easy development.
