On a quadcopter All-in-one board, 2 MOSFETs on one of the brushless motor driver are dead (connectivity between source and drain), causing burnt motor windings. The markings on the 2 MOSFETs are "L0302A 2121A" and "L0302A 2119A", any idea what those are?
Attached please find the image of both sides of the board, the dead MOSFETS are circled in red.
Possible useful information: the All-in-one board is "GEPRC GEP-F411-35A AIO", the motor driver's max continuous current is rated at 35A, and burst current at 40A.
Thank you in advance for the help.
