0.36 inch 3-digit 7-Segment 4.8V-30V variable precision digital display DC voltmeter

Description:
4.8 - 30V 3-Digit 7-Seg Voltmeter Display is a cheap and bright voltage display. It is able to display voltage measurement from 4.8V to 30V with an accuracy of 0.2V at below 12V and 0.02V above 12V. Comes with 3 digit seven segment display. A very simple yet useful display to monitor your voltage reading or measurement. Simply connect the red wire to the positive supply, and black to negative ground. The display has a microcontroller that will read the voltage, compare it to a stable reference and output the voltage to the 7-segment display. Applicable for most project that requires voltage display from 4.8V to 30V.
