2 - Select power for logic side

Autoquad ESC32 is an "Opto" style ESC. It means it has no built-in BEC – so It

cannot powersupply anything but the motors and itself.

The ESC32 has two options for powering the logic side:

• On-board 3.3V LDO powered by main battery (Vb)

• 5V coming from UART or PWM interface (V5)

In most cases (especially when using LiPo batteries larger than 3S) it is

recommended to power the ESC MCU with 5V from the PWM or UART interface

– either from an external regulator or a UBEC hooked up to the servo rail on

your FC or receiver.

Selecting 5V, also means you can power up the logic side separately when

flashing firmware or altering settings over 1-wire or UART interfaces, without

the need to power up the motors.

When using the 5V option to you must always DISCONNECT MAIN INPUT FIRST

before disconnecting the 5V power to PWM or UART interface - disconnecting

5V while the main is still powered can damage the ESC.

To select the power source for MCU, locate the small solder jumper in the

corner on the power side. It's a simple 3-way solder jumper and works by con-

necting the middle pad to either the "Vb" or "V5" pads.
