  • Perfect for observing VW Beetle 1200 mk1974 system voltage (6 Volts)

    posted by Heinzl

    The display is used to observe the voltage level of my VW Beetle 1220 mk 1974 with 6 Volts system before starting and while driving. One only has to connect the two wires at the right points to make it work when voltage is applied. The refreshment rate of the display is just right so you don't get nervous from digits changing if voltage level changes.
    I have ordered a second display for further experiments.
    Great, I love the blue digits!
  • Great Voltmeter!

    Small boardVery good solder -high quality surface mounted, I was amazed really!Useful range (4.5 - 30V is more than I will ever use)No additional power source needed.Low power consumption.There is a trimpot, and you can calibrate it when needed.PCB is very small, but you have two mounting holes on edges!
    You can use it in in many many DIY projects, will fit anywhere!I am going to fix it to home emergency power supply unit.
    I recommend buying this Voltmeter.Will work as expected.
  • 5-Digit LED Precision Meter & Display Combo

    posted by RAndris

    Ready to go meter. This tiny meter is awesome, red LED display is highly visible, response time is fast. Good measurement averaging and average pulse immunity. No separate power supply needed if measuring voltages > 3.5V and source allow to supply from it.
    I am using this meter to check and monitor power supplies instead of carrying multimeter around.
    Compared full range voltage readings with 5-Digit multimeter - precision is perfect for price.
  • Teeny tiny!

    Bought this to put in a bench-top power supply... It's compact and accurate enough when compared to my multimeter. The display is good and it has mounting hole on the pcb. No external power required.
    This will be a part of a benchtop variable DC power supply module I am building
    I was going to build one, but for the price... it's a no brainer! I like its size and it seems well assembled
  • nice display

    I like this thing a lot, i had another one in red without the frame and it didn't look as good as this one, the blue color is nice and even, no dark sports, and seems fairly correct to me. The black surrounding around the display is made of the same material as most dashboards so could be integrated very wel in a dashboard without noticing. The display has a matte cover over it to enhance visibility in the sun or bright daylight.
    none
    This is the way to go is you want a nicely finished display with a case to match so you can build it in in something
