Adafruit IndustriesMini 3-Wire Volt Meter | 705

With Adafruit’s Mini 3-Wire Volt Meter, you can have live voltage readings for your project. The Volt Meter reads from 0 to 99.9 VDC with ±0.1 V precision thanks to its internal microcontroller and voltage reference. The meter simply needs to be powered by a 4.5 to 28 VDC source and its reading lead will measure whatever point of your circuit needs inspection. The bright green LED readout also has mounting tabs to easily attach it to a box or plate.
