Описание товара
ESP8266 WIFI Dual 2/4-Channel Wifi Relay Module 110/220V Switch Controller Board AC/DC ESP-12F Development Board For Smart Home
2 Channel
describe
1. Onboard mature and stable ESP-12F WIFI module, large capacity 4M BYTE FLASH;
2. The I/O port and UART program download port of the WIFI module are all led out, which is convenient for secondary development;
3. Onboard WIFI module RST reset button;
4. ESP-12F supports the use of development tools such as ECLIPSE/ARDUINO IDE, and provides reference programs under the development environment of ARDUINO;
5. Onboard 2 5V relays, output switch signal, suitable for controlling the working voltage of AC
Load within 250V/DC30V;
6. Onboard power indicator, 1 programmable LED and relay indicator.
7. Product size: 78*47mm
Burning port:
ESP8266's GND, RX, TX, 5V are respectively connected to the GND, TX, RX of the external TTL serial port module
,5V, IO0 needs to be connected to GND when downloading, and then disconnect the connection between IO0 and GND after downloading;
NC: Normally closed, the relay is short-connected with COM before it is closed, and it is suspended after it is closed;
COM: public end;
NO: Normally open end, the relay is suspended before the pull-in, and short-circuited with COM after the pull-in.
