Today I saw a question on the hobbyking.com if the BEC of an 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 and a connected to it receiver draw. So I take 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 KK board (or the HK Multiwii AIO board) and a receiver, as both draw 0.2A.
