Mic si puternic

Foarte util pentru automatizari.

Pro:
- pretul
- poate fi folosit si "stand alone".
- ofera 2 pini GPIO
- firmware-ul poate fi schimbat. (eu am pus unul personalizat de NodeMCU)

Contra:
- in timpul boot-ului GPIO 0 si 2 trebuie sa fie neconectati sau pull-ul... ceea ce face destul de grea folosirea lor ca iesire.
- in cazul in care se foloseste o rezistenta de pull-ul modulul de cam incalzeste

Atentie!

Daca la alimentarea la 3,3V (cu regulator 3v3 sau cu solutia de divizor de mai sus) chipul ESP8266 se incalzeste puternic atunci este cazul sa reducem alimentarea la 2,5V si putem pune regulator de 2v5 + translatoare de nivel 2v5 ...3v3 ..5V (solutia pretentioasa) sau rezistente de 1k pe liniile de RX/TX etc.
