model: p3488
180-13448-DAAA-B01

The silk screen of the broken component is U43. What is it and can I replace it separately to repair it

Repair of Jetson Nano module not supported or recommended. If the fault is on the carrier board, please refer to Jetson Nano Developer Kit Carrier Board Design Files (P3449 B01) which includes schematics, layout, assembly drawing, BOM Log in | NVIDIA Developer

Thank you for your answer, but the fault is not on the carrier board, the fault is on the background of the Jetson Nano module, The label of the damaged component is U43。 what can i do to fix it ? Why doesn’t your module have overvoltage protection。

6

Due to small form factor of Jetson module all voltage protection cannot be on the Jetson module and hence it needs to be on the Carrier board and also depending on your user environment it needs to be adapted to meet your needs.

Please, could you tell me the name of the component U43? this component is burnt out.
