20pcs 0.36 Inch DC0V-32V Red LED Digital Display Voltage Meter Voltmeter Reverse Connection Protection
Feature:
Package includes:
20 x Voltage meter
● Super high precision
● Ultra-low startup voltage, red minimum 2.5V, green minimum 2.7V, blue minimum 3.0V. When the power supply voltage is lower than 3.5V, only the brightness is lowered, but the measurement accuracy is not affected.
● With reverse connection protection, it will not burn.
