User Manual for ESP-12E DevKit
Introduction
ESP-12E is designed and developed by Shenzhen Doctors of Intelligence & Technology (SZDOIT) based on the Ultra-low
power consumption UART-WiFi ESP8266, which is specially for mobile devices and application of IoT (Internet of Things).
Now, ESP-12E is widely applied to internet, communication in local area, intelligent home, industrial control, handeddevices, and etc.
ESP-12E DevKit is used the design of on-board antenna and encapsulated by 2.54 direct insertion. It is very convenient to
debug and install device.
In ESP-12E DevKit, Hardware API operation is encapsulated by Lua language, which can avoid the hardware difficulty for
sorfware engineers, and then can speed the develop of products.

Start quickly
ESP-12E DevKit is already built-in Lua fireware with AP mode, together with the following steps:
1. Let ESP-12E DevKit connect to your computer with MicroUSB. ESP-12E module would be brighten with blue light, and
then the light is out;
2. If the driver is not installed in your PC, an information would be pop-up to show an unknown device. At this time, a
serial-driver for CP2102 must be installed by the OS.
3. Open the wireless network to look for a WiFi wireless network named as DoitWiFi (its SSID), and connect it. If use
mobile phone brower, please visit the source code in this book.
4. The initial passowrd is 12345678.
5. Input 192.168.1.1 in the brower, then have
6. Click "D0", the light is brighten with blue color;
