Review on Songhe LM2596S LM2596 Buck Converter with LED Voltmeter Display - ⚡️ 5pcs Bundle, Adjustable Voltage Step Down Module, 4.0-40V to 1.25-37V, 2A Power Supply by Bobby Posner

I love these modules. I received two yesterday and I've already found a use for them. I use one to drop the voltage for powering my 3D printer to power some fans, works like a charm. I've found that the new fans aren't cooling as efficiently as the fans they replaced, so I just increased the voltage a bit and it works great. I use another to drop the voltage of some 24V LEDs I bought to light my workspace. I broke the included remote, and I don't have anything on hand that can PWM at 24 volts, so I have no choice but to run all channels at max brightness. A cheap analog solution to a digital problem 😂
