If you don't know how to use this product and you can contact us, we will send you more details, thank you ^^

Describe:
12V Dual Wifi Relay Module uses ESP-01 as wifi module and is compatible with 8-bit MCU chip. Only a simple configuration process can realize wireless control of 2-Way Relay via mobile app.

Functions:
1. Onboard wifi module ESP-01 and high performance microprocessor stm8s103.
These 2 modules have 2 working modes:
Mode 1: the phone is directly installed on the wifi module.
Mode 2: Equipped with mobile phone and wifi module on Router
Additional Features: It can also be used as a USB Relay when pulling the ESP-01 out.
3. Delivery distance:
In the open environment, when the mobile phone is plugged into the wifi module, the maximum stable transmission distance is 100m.
4. When the wifi module and mobile phone run simultaneously on the router, the transmission distance depends on the signal strength of the router.
5. On-board DC 12V, 10A // 250V AC 10A // 30V relay, can pull continuously 100,000 times, with Diode discharge protection and short response time.
6. Use smartcongig technology to complete account and password configuration on mobile phone App ESP-01 wifi module and Configure username and password memory function.
7. Board mode selection and real-time working status indicator.
8. UART debugging interface and STM8 swimming program download interface.
9. Table size: 59*40mm

Pack:
