Review on 💧 Waterproof Buck Converter: DROK 090586 DC-DC Step Down Voltage Regulator 9-32V to 5V, 10A 50W Power Supply by Cameron Reed

No, I didn't connect the wires backwards. I really have the bad part. Too bad I didn't measure the performance before installing it, but I assumed I actually got what I paid for. Instead, I installed it in my car, stuck my raspberry pi in, and the pi started smoking, phew. He's dead. Killed Raspberry Pi 3B+ and 7 inch screen. I measured the output on the workbench, spent a few hours double and triple checking the wiring, and found that the 12V input produces a 12V output. Today is a big lesson BEFORE INSTALLATION BEFORE INSTALLATION, MEASURE POWER BEFORE INSTALLATION Cheap bullshit.
