Made a mistake of connecting pin-1 NC of MPU6500. Will it affect my pcb?
The datasheet says &quot;do not connect&quot; about that pin.
That is the best answer you have unless you ask the manufacturer. We cannot possibly know what is the internal function of that pin, or if it matters, or if it is even connected.
The chip status is also &quot;not recommended for new designs&quot; so it might not be available for long. So while you have to change the PCB anyway, you might as well change the chip to something that is future proof.
