Review on 🔌 10pcs MakerHawk LM2596 DC-DC Buck Converter: High Efficiency Step Down Voltage Regulator, 3.2-46V to 1.25-35V, 3A Adjustable Power Supply Module by Antonio Baker

All 10 are individually boxed. They work as expected. Be sure to set the voltage before connecting the load. According to the data sheet, the maximum diode current is 3 amps. If you plan to run this above 2 amps I would consider replacing the diode with one with a higher current rating and possibly less voltage drop. The included SS34 gets pretty hot at 2.5 amps. We also recommend buying a small heatsink for the ESC. I would like the vendor to include it as some other converters on the market come with a heatsink that comes with the product. The inductor included in the kit also gets very hot. A toroidal inductor would probably be better than SMD. It will certainly run at 3 amps peak current, but I'd keep it at 2 amps or less sustainably.
