Description
ESP12-F Relay Board
This is a general-use ESP12-F Relay board with Mains voltage on the Common of the Relay. An AC-to-DC power supply powers it.
Most of the GPIOs are broken out.
It features dedicated I2C headers ( 3v only), A DHT22 Header, optical isolation on the relay control line and additional 3v and 5v headers.
CAUTION:
The Relay contacts on this PCB are designed HOT ( Mains LINE voltage present on Common terminal). A maximum current of about 6A at 220v is assumed.
