How about heating issues at a higher voltage etc.? I remember reading that herelink air unit does heat up a lot, so will the heating effect be amplified by the supply? Wouldn’t that cause electronics to not perform at optimal capacity theoretically?
The air units heats, that’s a reality. It could be a bit hot but regarding all the setup i made with it, it doesn’t need an additional fan. It could be necessary if your drone do not have enough ventilations, but this case would be rare.
In most of the cases increasing the voltage, decrease the current flow = decrease the heat. But regarding the herelink, i’m not sure that the real heating part is the internal power supply, i bet on video or RF chips or something like that.
I tested the air unit with 5V, 7V and 12V and do not notice any significant temperature difference.
We just used a M4 ATX to power the herelink air unit and it reads a steady 12.25V, but it is slightly hot to touch. Is that normal or are we too close to the maximum limit?
