I am new with robotic in general. Currently I am using what I believe is the older version of BlueROV2. It has Raspberry Pi 3B on board. I just got myself the new Navigator board, but then I realized that the connector is not quite matching with the one in the Navigator (it can be connected to the Pixhawk1 px4 from 3DR Robotics).
The reason why I changed the board is because I can’t seem to get the data from the bar30 sensor (it kept outputting 0 for the depth data). I happened to have spares of bar30 sensors, I all of it with my Pixhawk but still couldn’t get any data. I thought it will be a good idea to get a newer board, but I am not aware of the port type. I can’t even get to power the mini PC inside. The fact that I am still using the RP3B instead of RP4 is also bothering me.
Do you have any suggestion regarding this? I am also not very familiar with port/connector types. Is there any alternatives (like adaptor for the sensor connector) so that it match to the port in the Navigator Board? Sorry for the noob-ish question but I would really appreciate any suggestion from you!
Our Navigator Retrofit Guide specifies the necessary parts, and walks through the relevant steps.
Note that the Navigator has hardware incompatibilities with the Raspberry Pi 3B, so won’t be properly usable with it.
It’s possible this is an issue with your Pixhawk’s port, but it could also be a problem with your autopilot parameters or your firmware version. I’d recommend flashing on a new firmware and setting the default parameters to make sure that’s not the issue.
We do sell an adaptor for connecting old DF13 sensors to the newer JST-GH ports, and our I2C Bus Splitter allows adapting multiple if you have e.g. a Bar30 as well as a Celsius sensor
I want to make sure one thing, by you mean “flashing the Pixhawk”, do you mean by directly connecting the Pixhawk to my PC and installing the firmware via QGround Control? Because I did that before too.
