Keep an accurate eye on voltage in even the tightest spaces with this compact mini digital voltmeter from Diymore. Its ultra-slim profile and 0.5-inch OLED screen make it a natural fit for embedded builds, control panels, and custom power supplies where a full-size panel meter simply will not fit.
Built around a 12-bit high-precision ADC, this meter delivers low detection error and steady, reliable readings across a DC 0-30 V measurement range. The crisp 88x48 OLED display shows three-digit white text with an automatic decimal point, so you can read your voltage at a glance.
Whether you are monitoring a bench supply, checking a sensor rail, or keeping tabs on a vehicle battery, this little meter gives you real-time feedback without taking up valuable board space.
