Using a multimeter, measure between pin 4 (GND) and pin 8 (VCC) on your SOIC8 chip. You should see either 3.3V or 5V depending on your programmer’s jumper. If you see 0V, your clip is misaligned or your CH341A is dead. If you see 5V on a 3.3V chip, —you may have damaged the chip. You need a 3.3V adapter board (or modify the CH341A by cutting the 5V trace).
