🔍 SMAKN 0.56" 3-Digit 3-Wire DC 0-100V Blue LED Voltmeter Voltage Display Module with Reverse Protection Review

I have this on my golf cart, the first time it got a little wet it leaked and has been broken ever since. Tensions are low now. It doesn't take long for the manufacturer to make these weatherproof

This display is very accurate and very sensitive. Measured to 0.1V when the 3rd wire is used to power the device separately. Ideal for variable speed annealers such as Annealeez and Giraud.

I have two projects in my car that show the voltage on two different circuits. Fits easily in my project box. I've used several of them for various purposes over the past few years and one of them failed. With such prices and standard sizes, replacing it wasn't a problem.

This is a very cheap upgrade solution for annealleez to have a digital readout for tension control and repeatable results when annealing brass. I just log what voltage I set to get the right temperature for the different calibers, which makes finding the right glow a little easier.

Used as a mod for PC electronics. Three wires soldered on made wiring very easy. Thank you for that touch. The hole is cut, ground and inserted in about 15 minutes. Then connected for 5 and everything in reverse order. Works like a champ.

Installed a counter on the Annealeze Case Annealer to set the speed. So far he has done his job. This is just a simple counter, so installation is up to you. It has snaps that fit the hole so you need to make provisions for installation. There are some helpful videos on Youtube showing you options.

I suspect that positive feedback on this product comes from buyers who have been using the product successfully with 12V, 24V and maybe 36V. I suspect negative reviews like this are for higher voltages. Simply put, when connected according to the instructions (to 48V - white plus - black minus), flicker appears, and then they go out. I ordered two, one came out with a bang, the other didn't work. I ordered a replacement thinking I was just unlucky, but the result is the same. I don't understand

I was specifically looking for a blue LED 3-wire voltage indicator for a power supply I was making. The 3rd wire enables measurements below the display supply voltage. I wanted to go down to almost zero volts. I was a little hesitant to buy this one as the display didn't look like it had a color filter in front of the display. The color filter covers the unlit LED segments, improving the aesthetics. I received the display and it has no filter. Look at the first photo and the display is…
