Simple ESP8266 relay board, i have been thinking how to make this board different than other similar boards and only thing hich comes to my mind is to make possible to hook the load directly, not just by cutting one line.

However, maybe in next version i'll do that.

Until then, this is simple board with programming connection and exposing other unused pins, also, i made interface to use bit T0-220 package LM1117 or SOT-89 HT7333 voltage regulator and i made relay pins also exposed, just in case someone wants to manipulate it directly.

Everything else is visible in schematics.
