As a Hobbyist, we need measure voltage at any time. Put a voltage meter anywhere with this very handy display. These are often used by RC hobbyists for keeping track of batteries but we thought it would be great on a breadboard or enclosure.
Specifications:
- 4.2V to 30V DC measurements
- 0.1V precision
- 3-4mA draw
- Blue LED display
- For use with positive voltages only!
- Dimensions PCB: 45mm x 26.5mm
- Dimensions Display: 34mm x 17mm
- Total Size: 48mm x 29mm x 21mm
- Weight: 15.45g
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 display the voltage with 0.1V precision on a 3-digit 7-segment display.
It works from 4.2V up to 30V so it will be good for nearly any electronic project. The meter draws 3-4mA to power the microcontroller and display. This particular LED display is a nice vivid blue, which we found very readable. Mounting tabs make this module easy to attach to any box or plate.
Package includes:
- 1x Voltmeter
- 1x Pair of test hooks
- 1x Pair of alligator clips
