ESP8266 ESP-12 Dev Board

 

USing steps:
1.Install IOT.APK into your mobile phone
2.Using ESP8266FLASHER download software and update the firmware into the module
3.Put on the AA battery, using mobile phone search network AI-THINKER
4.Add the router,password: ai-thinker
5.After all successed ,you can use your mobile phone to control this module
Please note:
Step 1 :it doesn't need any router, the mobile phone can directly control the module
Step 2 :You can use the mobile phone WIFI control module
Step 3 :Once the module is mounted to the server, the mobile phone can use 2G 3G 4G network flow control the module
All the above steps finished,then:
Using mobile phone direct ly control the module AP, then control dimming switch IO
Or based the step 1 , enter the configuration menu, also can enter the home network
Once the module connect to your home network successfully, the module will automatically mount to the Server

ESP8266 WIFI cloud Dev Board

 

Description:

This cheap and small Wifi transciever is the perfect solution for home Automation and IoT applications. It can be the replacement of your NRF24L01, it can talk to your Wifi router directly through the UART MCU's (Rx, Tx).

The ESP-12 module is one of the most complete of the ESP family as it allows you to use biggest amount of pins of all of them. You can program this module to work stand alone with the Arduino IDE or with LUA as NodeMCU.

It has an LDR and a WS2812 led already on board for your projects. The board comes with a CH40 micro USB module to program it.

The ESP8266 highly integrated chip, including antenna switch balun, power management converter, so with minimal external circuitry. The system is equipped with ESP8266 manifested leading features are: energy saving VoIP quickly switch between the sleep / wake patterns, with low-power operation adaptive radio bias, front-end signal processing functions.

This version, the ESP8266-03 is one of the smallest versions of this module. It includes a buil-in ceramic antenna.

Specifications:

LDR Lignt Sensor on board

WS2812 Led on board

3x tactile buttons (1x in the Witty board and 2x in theCH340 board)

Supports 3 modes: AP,STA,AP+STA

Dimensions: 24mm x 16mm

Micro USB connection for power and/or programming
