Sonoff POW - Inside back view

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

Issues

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.
