DC 12V WiFi Relay Module 4 Channel ESP8266 ESP-01 Wireless Relay Switch Board 4 Way Phone APP Remote Control Relays Board

Wifi Relay 4 Channel 8266 ESP01

1. Onboard ESP-01 WiFi module and high performance microprocessor STM8S103.
2 The module has 2 working modes:
Mode 1: The phone is directly install on the WiFi module.
Mode 2: Equippe with a mobile phone and WiFi module on the router
Additional features: It can also be use as a USB relay when the ESP-01 is pull out.
3. Transmission distance:
In an open environment, when the mobile phone is install on the WiFi module, the maximum stable transmission distance is 100M.
4. When the WiFi module and the mobile phone are simultaneously carry on the router, the transmission distance depends on the signal strength of the router.
5. On-board 12V, 10A // 250V AC 10A // 30V DC relay, which can continuously pull 100,000 times, with diode discharge protection and short response time.
6. Use Smart technology to complete the account and password configuration on the APP ESP-01 WiFi module on the mobile phone, and configure the username and password memory functions.
7.Board mode selection and real-time working status indicator.
8. Reserve UART debug interface and STM8 SWIM program download interface.
9. Board size: 59 * 40

Wifi Relay 4 Channel 8266 ESP01

The 12V ESP8266 4 channel WIFI relay module uses ESP-01 as the WIFI module.

And with the mature and stable 8-bit MCU chip.

The wireless control of the four-way relay in the local area network can be realize by using the mobile phone APP in a simple configuration process.
The configuration of the account number and password of the ESP-01 WIFI module can be complete on the mobile phone APP.A

nd the configured account number and password have the function of power-off memory.
