two modes: (1)

Mode 1: Cell phones carry on the wifi module directly (2)

Mode 2: Cell phone and wifi module carry on the same routerAdditional function: As an USB relay module when unplug the ESP-013,

Transmission distance: (1) In the open environment, the maximum transmission distance is 100m when the cell phone carry on the wifi module directly; (2) when the wifi module and cell phone carrying on the same router, the transmission distance depend on the router s signal intensity; 4, Use Smartconfig technology of ESP8266 to configurate the password for theESP-01 module with APP5, On-board 5V, 10 A / 250 v AC 10 A / 30 v DC relay, absorb 100000 times continuously, Module with diode effusion protection, short response time6, On-board model selection and working position indicator LED7, On-board preserved UART debug interface and MCU program interface8, Size: 59*40mmInterface
