I've started rc plane but with internet connection instead of regular radio. My plan is using Ai-thinker A6 gsm module so I can use it as live stream camera and control servo together with blynk. Currently I use usb tethering from my android to test it.
As an aeromodel project, I have 3 Tower pro sg90 servo's and will bought dc motor in future. I've successfully control 1 servo but I don't know how can I put the others since I hear direct supply from my pi-zero gpio will broke my pi-zero.
Is there any module or what can I do to supplied power for my 3servos and a dc motor? I am afraid it will conflict with gsm module if I use a servo-control module like adafruit 16 channel.
