The link in the topic title so it's easier to click: [//forum.arduino.cc/t/avrdude-error-yikes-incorrect-device-signature/558024/2](https://forum.arduino.cc/t/avrdude-error-yikes-incorrect-device-signature/558024/2) Signature 0x000000 to my knowledge means a bad connection. Please provide details as to which programmer you're using, the target board and the wiring. ---

The first question is if COM5 is the PL2303? Does it disappear from the IDE if you disconnect it. The second question would be what Windows device manager thinks of your PL2303? ---
