iTead Sonoff Pow with Energy Monitoring
The unpopulated header in the Sonoff has all the required pins. My board has a 4 pins header. They are (from the top down) 3V3, RX, TX, GND
The original Sonoff has some connectivity issues. This is probably due to the antenna placement close to live lines. It works fine if it's near the AP, otherwise, it's often reported to lose connectivity.
