===================
mkdir _build
cd _build
cmake -DCMAKE_TOOLCHAIN_FILE=../powerbar/toolchain-avr-gcc.cmake ../powerbar
make
make upload_powerbar
Fuse bits:
====================================
low fuse: 0xef
high fuse: 0xd9
Common lantronix device settings:
=================================
Configurable Pins:
CP0: GPIO (unused)
CP1: Modem Control Out (DCD)
CP2: Modem Control In (DTR)

Errata for rev. 0.1
===================
- GPIO is not connected to WiPort; Connection management does not work
- terminals on relay board have wrong orientation
TODOs for revision 0.2:
=======================
- GPIO should be named DTR
- old DTR should be named DCD
- DCD should be connected to INT0 or INT1
- rotate WiPort footprint
- rotate terminals on relay board
- move more SMD parts to the top side
- narrow boards by approx. 0.5mm
- make COM_RST pull-up a pull-down
