Hey guys,
I recently startet a new projekt in which I want to build my own self driving boat (3d printed catamaran) and wondered if some of you could help me with the flight controller selection since i’m new to this topic.
The goal for the projekt is to be as “round” as possible, so i’d like to be able to use all features regarding ardupilot boats and the price for the fc doesn’t nessecerily be the lowest. But it should be easy to get without a long shipping time because of external factors and other deadlines.
So far I tried to get my hands on an H7 fc since I don’t need to worry about restrictions on further code usage and modifications. Since I went for the enclosed versions the selection wasn’t that big. Unfortunately most of them won’t be here in time (Germany). An example would be the Holybro Pixhawk 6C Mini with the NEO 3 GPS.
Do you have any recommendations with similar capabilities (or are there other requirements)?
Could you maybe also help me in terms of peripherals?
Do I need more than a GPS system with compass since it already contains those: IMU ICM42688-P(V3)+ICM42605; Baro: Infineon DPS310 (I2C2)?
The CUAV NEO has the same GPS but a better compass, with a boat you’re generally going to be clear of any metal objects that can give interference.
If your planning on using it in an urban area with lots of metal around you should look at RTK moving baseline GPS yaw rather than a compass. As large amounts of steel like a steel enforced concrete pond can cause magnetic interference vs something like a natural lake that is fine with a compass.
avoid Radiolink, they have issues with compatibility.
I would print the top and bottom of the mount and join them with some carbon tube. check thingverse or yeggi there is probably a mount for the GPS that you can modify.
I actually couldn’t find the right files.
I think im gonna go with the stand since I won’t have to worry about the different parts.
(I could make it myself buts it’s not cheaper or faster)
But please tell me if I need anything else or if i’m good to go with the Matek H743 Wing and the Holybro M9N GPS?
The telemetry radio is a peripheral device. It connects to a Serial Port which could be a connector, pins or solder pads. You have a soldering iron right?
the Matek Wlite uses all Dupont 2.54mm connectors like a servo for all the ports apart from CAN and I2C2 so buy one of these kits and add the connectors to the telemetry and GPS wires.
there are lots of youtube videos that show how to crimp servo wires.
