As someone has put up an article entitled “ESP8266 Killer?” I thought I’d better step in..
There are two boards to look out for on Ebay – the EMW3165 - http://goo.gl/ccWgtT
and the NL6621-Y1 - http://goo.gl/qdMhtm
I noted one article suggested the EMW3165 was “just a dollar more than the ESP8266” – just in case anyone believed that – a simple comparison of Ebay prices brings the ESP-12 in at under £2 the NL6621 at £3 and the EMW3165 at £8.52
So I don’t think Espressif have anything to worry about yet and one could ask where all the documentation and examples are and development systems for these boards…
Anyone know better than me on this one?
