I just built my quad drone, soldered all wires taking care of everything and didn't notice any damage to the board. I was able to connect using betafpv, still under configuration, but it connects, the sensors look good. In order to test the motors I connected the 4S battery, the drone brings some beeps and leds get on near the usb-c port.

We have the following leds:
Gyro, MCU, 9V, 5V, 3.3V, VCC

When i plug the battery, I can hear a kind of a song, followed by a kind of TRIMMMM and 3 beeps. MCU led keeps off and all others on.

Should I be concerned?
