Review on π UCTRONICS DC Buck Converter Module - Step Down to USB 5V Transformer, 6V 9V 12V 24V to 5V 5A Dual Output Voltage Regulator Board [2 Pack] by Joe Unruh
Both modules are defective
Both modules are defective. The first shorted out my 9V battery connected to the power supply input, but it worked fine on the DC jack connector. The second only worked sporadically at first. I found that the output capacitor has a bad connection. When I pressed it it worked, but then it fell off.
- Awakens confidence
- Out of fashion
