Hi everyone,

I’m using a Jetson Orin Nano Developer Kit, and I accidentally connected a 12V power supply with reverse polarity (positive and negative were swapped). After that, the board stopped working, and I found that one of the ICs near the antenna module (possibly power-related) is visibly burnt.

🔧 Problem Summary:

  • Reversed 12V DC input
  • Board no longer powers on
  • One IC appears burnt
  • I would like to identify the component and know if it’s replaceable or if there’s a possible repair procedure
