Good to know getting better, you can try the LCD 5110 or SPI LCD onto the shield, and use external power supply. It is much more easy to monitor. 


We tested this with a hair dryer, about 2-10A, but the output ranging is not a lot, probably need more code work. If you have any su

Hi,

The 100A sensor has too large range normally used for big devices or buiding, if the input is a few amps it won't change a lot, maybe you can try the 30A version. 


Also make sure all the settings in the sketch is correct, make sure the setup is for 100a not 30a, you ca

If I compare correct, pro mini use regualtor MIC2505, which quiescent current is 5uA, but only 150mA delivery, the upgrade version MIC2519 is better 8uA/500mA. Our current use is AP2112 but 55uA quiescent and output up to 500mA. Which also add this to test later.

Hi, we will need time to check the low power, not really good at this. We have a replacement IC instead of Atmega328, which should work fully same. but 1.2 usd cheaper. Totally each board could be 1.5-2 usd cheaper for bulk I think.
