so im building a rather large multirotor(drone). an octocopter.this is not by any means my first model ive build dozens, i pretty well know how to make them. ive 3d modeled it part by part. and i will soon have my cnc router to start working on it and i will do several projects but my 1 issue i cant figure out. i petty much have my heart set on a power distribution board. i know it works as ive used them and seen them. but how to make one. not manufacturing, i believe i can mill out a test board with the cnc, but rather the design processes is enough to stump me.
specifically, i need to pull an s***ton of amps. ether about 145amps @ 25volts or 240 @ 16volts, haven't deiced which is better.
all it need to do is transfer power to the hungry motors and things from the battery and if i where feeling confident maybe a few voltage regulators and simple circuts to make the build neat. i really want to go all out for this model as it will be a centerpiece. something i built my self that was as maxed out as possible.
note that the big number of 145/240amps disperse pretty quick. its only 18/30amps per motor and with the plug in the middle it will divide the amps at the connector
also note that i may go with the larger number. because the speed controllers are still optimized for 4s lipos at 16volts. and several drawbacks to 6s power at 25volts means dealing with massive amp draw at 16volts,
where should i start. what software should i use, and how do i determine the trace size to pass the amps i need.
