What kind of help?
I am presently completing the PCB layout and then I’ll print some prototypes.
I hope to get it by the end of the month.
At present I am struggling with everything I want to put on the board VS the space I can use. I wishes I could plug the pixhawk straight in but its not possible at present.
I have changed this last design to have one current sensor per ESC and additional sensor for other peripherals.
I also have signal conditioning to sum all those up and an isolated op amp for voltage measurements so it can still go in the pixhawk.
Once I have tested this in depth.
I’ll be selling this board naked or populated for all the DIY people out there.
I have also designed a piggy back relay board and a piggy back arduino board with fans that will mount on this main PCB.
Coming later will be small opto-coupler boards to isolate the PWMs but I will need a lot of tests to make sure this will perform. I might have to modify the pixhawk a bit.
The Arduino board has a traco power isolated DC-DC 12VDC 60W module for all the peripherals.
This is all in complement to my subsea power mod so I can measure voltage, currents, temperature etc.
I’ll keep everyone posted…
