It's available now from Sparkfun! $59.95.
And cool home page promo on the Sparkfun site here.
Here's a quick FAQ for people just now coming to the site, or hearing about ArduPilot Mega for the first time:
- It is designed to work with an IMU "shield" (board that fits on top) that contains all the sensors. That board will be available by the end of May. The latest info on the shield is here.
- You'll need two right-angle 3x8 connectors to attach your RC gear.
- The ArduPilot Mega code will build on ArduPilot 2.6 and be available in about a month.
We recommend this board just for people who want to beta test or tinker. For regular users who want a plug-and-play (ish) experience, it's best to wait a few weeks for us to release the IMU shield, code and documentation. (The Sparkfun board will also be tweaked a bit, with mostly cosmetic changes to make some pin labeling clearer, in the next batch.)
