These are really cool boards to be able to monitor both AC and DC current. I have so many uses for them so will be buying more. The only down side to these boards it there is no way to measure their max rating of 30 amps with the connector on them maybe 10 amps as 14 gauge wire is the biggest wire I could fit in them. But the boards are meant for testing and learning so if you wanted to use the max current the chip is rated for you would need to redesign a PBC with traces and connectors that could handle that much current. As for me I don’t need to measure more than 10 amps and in most of my projects usually less than 5 amps. That being said they are great for many arduino projects.
