USB Indoor/Outdoor Thermometer

This is a simple design that demonstrates the USB peripheral on the PIC 18Fs. There are a bunch of examples for the 18F4550 40 pin chips online, this design demonstrates the smaller 18F2550 28 pin version.

The PCB uses surface mount parts, but all components are available in through hole versions.
