The product is shipped WORLDWIDE from Sydney, Australia.

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. It 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 the project that requires voltage display from 4.8V to 30V.

Features:

  • Input Voltage: DC 4.8-30V (Input voltage higher than 32V will damage the product)
  • Minimum voltage display : 2.2V (dim light)
  • Operating Current: < 23mA
  • Refresh Rate: 300ms
  • Accuracy at lower than 8V: 0.2 V
  • Accuracy at higher than 8V: 0.02V 
  • Seven segment display colour: Red
  • Red Colour Wire: Vin
  • Black Colour Wire: Ground (GND)
  • Wire length (Red and Black) :15cm
  • Dimension (mm) : 33 (L) x 15 (W) x 10 (H)
  • Weight : 10 g

 

How To Use: 

  1. Connect the seven-segment wire to your voltage supply, battery or voltmeter.
  2. Connect the Red Wire (Positive) to Vcc or Vin.
  3. Connect the Black Wire (Negative) to ground.
  4. When the connection is done, turn on your supply (if there is a switch)  if no switch, the seven-segment will automatically display your supply current output voltage.

Note:

  • Please be careful and ensure that your supply does not exceed the operating voltage because it could damage your Seven segment voltmeter display.
  • No polarity protection, please check the polarity.
