The UBEC’s input cable should be connected to the LiPo battery, and the output cable to the RX and FC. This leads to another argument, where to mount your ESC on quadcopter frame? just between battery and FC… basically it’s like connecting 5 ESC, but the UBEC isn’t connected to any motor :), Your email address will not be published. Switching BECs reduce the output voltage by switching the supply on and off several thousand times per second. I have a 5 volt soldering port on my PDB. That’s why this type of voltage regulator is not ideal for high input/output voltage difference or high current application.
no that’s absolutely fine, just make sure you are connecting the Ground with ESC signal as well!
and I’m honestly having a hard time picturing the wiring in my head and how everything should connect. 0000050128 00000 n
My battery leads solder on the VCC inputs, could I use one of the bec outputs either 5v or 12v to accomplish what’s needed for the esc’s to operate correctly?
Now I am stuck, they look exactly the same, they have the same amount of wires. It’s used when ESC doesn’t have built-in BEC, or standalone power system is required. Thank in advance. Hi!
