BG has a couple BEC on sale. Switching is obviously better, but how can I tell based of the PCB whether it is switching or not? I assume the ones with more circuit may be switching or perhaps the ones with the large gray module?
These are the BEC I’m looking at:
Advertised as switching.
From my limited knowledge, I assume the second option is the best, but I just want to double check before I buy it, since shipping from china is sooo slow.
