Hey Ildar sorry for the late reply. Whether or not what I'm doing would work with Trimble only depends on what kind of signal the steering valve uses. I don't have software for Android yet. I also don't have any kind of kit yet. It's pretty much a make to order product at this point.
WE have the similar control valve like the Outback Edrive. So if I understand true we can connect Your Pixhawk autopilot directly to this valve. So is it possible to buy Your set together with Your program on tablet PC?
May be in the next step You can make the set on base Android tablet.
