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.

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. Connnect 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 switch)  if no switch,the seven segment will automatically display your suppply current output voltage.

Note:

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

Packing List:

  •  1 x 4.8 - 30V 3-Digit 7-Seg Voltmeter Display
I've only bought this for 3 months and used it only 4 times for my circuit, but the soldered black cable came off very easily. It stated here in the product that it has a warranty period up to 12 months, so I was wondering if I could get a new one with the cables soldered carefully? ( Leong Kah Hoe , 30/10/2020 )
