Dual Channel 5V 8-80V ESP8266 ESP-12F Development Board Network Wireless WIFI Relay Module

Features

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. RST reset button of onboard WIFI module;
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 signals, suitable for controlling loads whose working voltage is within AC250V/DC30V;
6. Onboard power indicator, 1 programmable LED and relay indicator.

Burning mouth:

GND, RX, TX, and 5V of the ESP8266 are connected to GND, TX, RX, and 5V 0f the external TTL serial port module respectively. I00 must be connected to GND during downloading, and then disconnected from 100 and GND after downloading.

Output end of relay:

NC: normally closed end, relay is short-connected with COM before suction, and suspended after suction; COM: public end; NO: normal start, the relay is suspended before suction and short connected with COM after suction.
