Digital Volt Meter (0.56")
Water Resistant / water resistant high precision low cost digital water resistant voltage meter - allows you to put a voltage meter anywhere with this very handy display package including damp/wet location like your boat, motorcycle, watercraft, off-road vehicle, trailer. Use to monitor the voltage of RC battery packs, solar panel installation, amateur radio backup power supply, bench power supply output, or put onto a breadboard to watch power into your projects.Simple two wire connection.
Simply connect the red wire to a positive power supply from 3.5 to 30VDC, and black to ground to power the display.The display has a microcontroller that will read the voltage, compare it to a stable reference and display the voltage with 0.1V precision on a 3-digit 0.56” 7-segment display. It can read from 3.5V to 30V DC so it will be good for any electronic project! The meter draws approximately 20mA to power the microcontroller and display.
