First time poster and newb DIY drone builder. So please pardon my ignorance.
I've sourced parts for a DJI Flamewheel 450 clone. Obviously the FC is the BBBmini, along with the recommended baro, gps, sonar sensors also picked up a genuine 3dr telemetry radio which will be connected via UART. Finally I've ordered a set of Castle Creations DMR 30/40 ESCs.
I'm left with identifying the PDB and motors. I have some used DJI 2212 920KV motors that I may swap out for some EMAX or Multistar 2213 or 2216 motors as I'd like the option of not having to modify props and be able to bump up to a 4s battery and carry heavier loads with 11 or possibly 12 inch props.
Any feedback on the motor is appreciated but not the goal of this post.
I've picked up a Matek HUBOSD8-SE PDB which has a current output for FC sensing. The output is a varied voltage to signify current passing through the PDB.
Will this current sensing method work with the BBBmini and arducopter? I assume I would need to configure this in arducopter if it does?
In this case how do I detect voltage? Does the 20k and 10k resistor on the BBBmini 1.5 board setup a voltage divider for voltage sensing by connecting the voltage input on the BBBmini to the positive battery lead on the PDB?
If this will not work I have another option below.
I also picked up a genuine 3dr power module which based on the recommended hardware for the BBBmini will work. Does the current and voltage sense lines from the power module to the current and voltage sense input lines on the BBBmini also using the 20k / 10k voltage divider?
Thanks for this board and this awesome resource!
