Very well made product

For Voltmeter with USB interface

I am really impressed with the product, and it works great plugged into a windows computer. My only problem is that I need to have it plugged into a Raspberry Pi, and no matter what I try to do, I can not get this to work on that platform. I see the API in with the bundled C# source, but it does me little good as the Pi is an ARM cpu not an X86 or X64 one, and all windows files (dll's) will not operate. I was hoping someone else has encountered this issue and could steer me in an appropriate direction.
I ordered 2 for the project I am working on, and both arrived promptly and packaged appropriately for the journey. Both have worked great from day one, with no issues to date. Would suggest anyone to buy as they are very well made, and the seller was very easy to deal with.

Good but..

For Voltmeter with USB interface

As described the unit is a small module that measures DC voltage and displays the result on a computer.
The pcb is well laid out and professionaly done.
The measured voltage is accurate to 1 mv or better.
The shortcomings are mainly no instructions of any kind on how to use the simple software.
For this reason I find it to be of limited use for any real data-logging application.

USB Voltmeter Monitor

For Voltmeter with USB interface

Works Great! Use it to monitor voltage output of monitor pins for Ham Radio Khune Electronics amplifiers and transverters. Took me a minute or two to figure out how to unpack the software, etc. as I am not a software guy, but it worked out fine. Thanks for a fine product... What I really want is a USB voltmeter with 4 channels, similar to the IP version.

Thanks again, 73 - Mike - KM0T

For TCP/IP voltmeter & relay

Documentation comes via email and shows everything of importance.

It is really just plug and play!

Connected it to a 12V PoE splitter, it got a DHCP lease right away. I connected the first voltage meter port to a solar batterie, connected to the IP via web browser and could immediately read the voltage value.

One small fault is that the label on the PCB for the relays are in the wrong order.

After discovering all SNMP OIDs, it was trivial to read and write with Home Assistant.

The board design looks very clean and solid.


Awesome!
