This project is no longer under active development. Both @Tiogaplanet and I have moved onto other projects.

This project is based on the now retired Sparkfun MiP ProMini-Pack.
The original Eagle files can be found on GitHub. They were created by
Sparkfun employee Casey Kuhns.
Project Goals
- Produce a functional version of the MiP ProMini-Pack to correct the MiP communication issue in the Sparkfun original.
- Run the ATMEGA328 at 16MHz instead of 8MHz. This allows the AVR to properly receive 115200 bps serial output from the MiP.
- Increase Vcc from 3.3V to 5V so that the ATMEGA328 can reliably run at 16MHz.
- Modify board layout to make it easier to hand solder the SMD parts.
- Use larger 0805 passives instead of 0603.
- Extend the pads on some of the SMD packages to allow for easier transfer of heat from the soldering iron.
- Port my MiP C API project to Arduino and refactor it to make it more closely resemble other Arduino libraries.
- This library can be found within the Arduino/MiP_ProMini_Pack_Library folder of this GitHub repository.
