ESP8266 Community Forum

- Mon Mar 30, 2015 7:54 am #13009 Hi,
I want to use ESP8266 to control windows, curtains, TV, replace some wall switchs... and, for that last reason, it needs to be small...

Here, in Portugal, we have 220V. So, I found these Step Down Voltage Regulator. It is the best way?


Thanks a lot,
Ribeiro Santos

add a small ams1117

and its far better (can drive more - like an extra oled)

It costs a bit more... but look saver.

A slightly more expensive solution (similar to the great Recom modules): http://www.ebay.com/itm/131424221544
