I am currently building a drone that I want to be a bit advanced so I am building code on both arduino and raspberry. What I have not figured out yet though is how i can power them both and preferably with one lipo battery to make it weigh as little as possible. And as It is a drone of course i have to be able to power it wirelessly.
Right now I successfully power my arduino pro mini 5v with a lipo 3s battery and a power distribution board as you can see in my image below. I also successfully put motor wires on my pwm pins for each motor so I can control them with my arduino code and it works great.
Now I am not sure what to do with my raspberry pi zero w board (i drew a red rectangle around it). Is there anyway it can share power with the 3s lipo or do I need something externally to power it and if so what should I look for? I have a store pretty close to me where I order from (electrokit) that has a broad range of items. I also look to connect them together so i can talk between the arduino and pi.
This is the power distribution board I use: https://hobbyking.com/en_us/hobby-king-quadcopter-power-distribution-board.html?___store=en_us
