Can i power the arduino from 5v Pin ?
i have 5v UBEC https://hobbyking.com/en_us/hobbykingtm-x3-ubec-3-5a-5v.html
i now only realized that Arduino uno Vin needs 7-9 volts. so i can't use this ubec to power it. (Arduino switching on when i connected ubec but it is unable to supply 5v at 5vPin)
(this is for future use, i dont want to do this now)
I also have afro esc https://hobbyking.com/en_us/afro-20a-multi-rotor-esc-simonk-firmware.html. can i used bec from esc to to power arduino Vin pin ?
