Powering the Hedgehog

Post by N4LRCC »

The Mobile Beacon (Hedgehog) installed on a UAV (Drone). Can the Hedgehog be hard wired to pin 1 (VCC +5V) and pin 6 (GND) of the serial connection for power and eliminate the battery? Or will this disrupt the settings every time the UAV power is cycled?

Thanks,

Rick

Hello Rick,

The normal recommended way is to power via USB. It is safer and better.
However, if you are reasonably experienced, you can disconnect the battery completely and solder your 5V source instead. Make sure that it not more than 5.5V in any case, it is not noisy, and that the source can provide peak current up to 1A without voltage drop of more, than 0.5V. And, of course, make sure that the battery is, indeed, disconnected and you know, what you are doing. Otherwise, the LiPol will just explode.

BR,
Maxim

Thank you Maxim,

That worked. It doesn't seem the Pixhawk serial ports have enough power output with the exception of the Telem 1 port that I need for my telemetry. I have connected the Hedgehog data to serial port 4 and supplied the power through a dedicated UBEC. This work great.

Thanks,

Rick
