Apologies in advance from the somewhat-unrelated-to-FOC question.
I am using an ESP32 dev board to control two B-G431-ESC1 boards. The ESP has a small oled display plus two rotory encode knobs connected to it. I tried powering it from the BEC output of the B-G431-ESC1 and it got quite hot, quite fast.
I am powering the whole system with a 12V psu. Perhaps it is better to simply use a buck convertor directly from the psu to power the ESP32. Any thoughts/suggestions most welcome and appreciated.
