How many amps (A) draw a flight controller and a receiver
Today I saw a question on HobbyKing.com if the integrated BEC of a Afro 30A ESC could power the famous KK 2.1.5 flight controller and a receiver. The BEC of the Afro ESC is rated for 0.5A. But on the HobbyKing site there was no information how many amps the KK 2.1.5 draw. So I took my Turnigy Watt Meter and measured the current to my KK board, receiver and my HK MultiWii and MegaPirate flight controller. Here are the results:
|KK 2.1.5 / KK2.0 board||100mA = 0.1A|
|HK MultiWii MegaPirate AIO||100mA = 0.1A|
|HK MultiWii MegaPirate AIO with Ublox GPS||180mA = 0.18A|
|FrSky 8CH 2.4G Receiver||100mA = 0.1A|
The answer of the question: Yes the integrated BEC of the Afro 30A ESC can power the flight controller and the receiver, as both draw 0.2A.
per 100 milliamp? I have a 5000 milliamp hour 6s battery and i am wondering if i can use a bec with a max draw of 3.5 amps to power my frsky 8ch receiver
Hi Carson, the receiver max current draws is 100mA. You can use the 5000mA 6S battery without a problem.
Please am using a 6s lipo battery and a 80amps ESC with BEC output of 5v 5a, can I use it to power my kk 2.1.5 without anyproblem
Hello, the 5A is more than enough, so yes, you can.
