Details for M30 board

1. Yes, just cut the 3.5 jack, connect cable directly.
2. accuracy and measuring active power. accuracy is high. active power, voltage, current , frequency, power consume .etc. these data value read from BL0910 chip directly, it's calculated by hardware chip, here is video demo : https://youtu.be/y3AuMg6DdqQ

thanks, the video explained a lot. 

I would like to monitor power usage of electronics/computers/TV.
With M16v2 that reports high power (50W for tv in standby where real power usage is 0.5W)

Can you maybe post some results of measuring non-resistive loads like that?

Would the 5A clamps be accurate enough to measure loads of 1-2 Watts ?

No calibration needed with this M30 setup?
