Review on ⚡️ Icstation Buck Boost Converter: Voltage Regulator Module with Over-Charge, Current, Voltage, and Short-Circuit Protection | DC 5.0V-30V to 0.5V-30V Step Up Down Supply by William Turner

So what is a device? Well, it can do a lot of things, and whatever it does, it seems to do it pretty well. This is a voltage stabilizer and can be used as a mini laboratory. Power supply Can "convert" DC voltage with increasing frequency. For example, a 6 VDC input can result in a 12 VDC output. It can "convert" DC voltage to frequency. For example, a 24 VDC input can give you a stable 12 VDC output. This is a voltage stabilizer, in other words, if you set the output voltage to 12V, the input voltage can range from 5V to 30V while maintaining a constant voltage. 12V output So far we've talked about voltage, but it also has a built-in current limiter. In addition, this device can be used as a DC power source and is ideal for charging sensitive batteries. The device may turn off when the battery is fully charged. I could talk endlessly about the possibilities, but let's take a look at some test results. Please note that the display turns on as soon as the input voltage appears. Turn on/off" only controls the output. That the device is not always reliable with an input voltage of 5V. Raise the input voltage to 5.5V and it will have stable performance! He adjusted the output voltage to 12V and varied the input voltage from 5.5 V to 30 V. The output voltage varied within 11.98 V and 12W This is real power for those who want to use it as a desktop or lab power supply.... How clean is the signal? Noise peaks are 16mV at an average voltage of 453 microvolts! The manual says a switching frequency of 180kHz but mine switches to 215.7kHz (higher is better). Very impressive. Attached is a screenshot of the FFT, aka harmonics Distortion (in purple).Very difficult to measure as there is sooooo little noise.isThe adjustment potentiometers are on the right side of the device.This means that after embedding this device in the case, you won't have any e can make more settings. I wish the potentiometers were accessible from the front. Of course, any experienced hobbyist can unsolder the potentiometers and move them from the front (twist potential wires or use a shielded cable to avoid noise). In short, an incredible product at an incredibly low price
