  • If you are using the same board, did you re-solder or solder the board/device when changing the device? It could be the board issue.

    Hello,

    The board used was originally designed for the 5CEBA7F23C7 chip, and then multiple boards were created by maintaining the same circuit and layout while replacing the chip with 5CEFA7F23I7.
    Is it correct to understand that, generally, when you change only the device on the same board, there are no issues with heat or current?

    Thank you.
