Overview
The NavStik autopilot comes from NavStik and consists of a main board with several breakout boards. Until now we have 3 flavours in the breakout board, the IvyPRO, the IvyEZ and the IvyLITE. Each of these breakout boards have different specifications, but since the main board contains all the sensors they will never change. Next to the autopilot it has the capability to add a Gumstix Overo on top for more processing power.
Breakout Boards
Since the NavStik doesn't have any real connectors or power management you will need a breakout board for your autopilot to make it fully functional. In this section we will give you a short overview of the three different breakout boards.
