ProductDescription : ESP32 Development Board 4 Way Relay Module Programmable Resettable Development Board for Smart House Control

The AC / DC powered esp32 four-way relay development board is equipped with esp32-wroom-32ewifi & ble module. The I / O port is fully led out and supports AC220V / dc5-30v power supply mode.

For esp32

Secondary development and learning, smart home, wireless control and other occasions.

Writing port: GND, Rx, TX and 5V of esp32 are respectively connected to GND, TX, RX and 5V of external TTL serial port module. IO0 needs to be connected with GND during downloading, and then disconnect the connection between ioo and GND after downloading; Connection of;

Relay output:

NC: normally closed end, short circuited with com before the relay is pulled in, and suspended after it is pulled in; COM: public end;

No: normally open, the relay is suspended before closing, and is short circuited with com after closing.
