Instructions download: https://github.com/IOT-MCU.. ESP8266 ESP01 ESP-01 Serial Wireless WIFI Module Transceiver Send Receive LWIP AP+STA for raspberry pi 3 ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

RGB LED:

This is a WS2812 or WS2812B RGB LED controller based on the ESP-01 /ESP-01S. With this board, your will easy to make your colorful display project Feature： *Main chip：ESP-01/ESP-01S（This board Not include the ESP-01/ESP-01S） *Interface：3Pin PH2.0 for WS2812 *Working voltage：DC 3.7V-5V (Support 3.7V Lipo battery) Usage： 1.Power supply：3.7V Lipo battery connect to the VCC GND (2.54mm male header) 2.Upload the code to ESP-01S(ESP-01) 3.Plug the ESP-01S(ESP-01) to the module

USB adpater ：

This moduel is an USB adpater programmer for ESP8266 moduels of type ESP-01. It is conveniently fitted with a 2x4P 2.54mm female header to plug the ESP01 (according to illustration picture 2) and configure or run it right away. A large 1000μF cap will help getting a steady 5.0V VCC from the USb bus and and jumper (on the right of the 2x4P header)(we don't offer any jumper !!!!) will help configuring the GPIO0 line according needs. The module is based on the USB-UART bridget CH340 from WCH which is compatible with all platforms. Note : for an usage with for arduino ESP8266 platform and for arduino IDE it is necessary to switch manually the GPIO0 state for working mode, in order to get a fully automatic upload it is most likely possible, for a very limited effort, to assign an unused control line from CH340 to driver the GPIO0 line (probably at the cost of a necessary logic inversion), refer to the CH340 datasheet and most important to the NodeMCU V0.9 which use the CH340 and already implements this solution, the schematic is open source and easily available.
