Product Specification Model NumberESP8266-01BrandESPWeight12gDimension49 x 24.5 x 13mmApplicationDATA TransmissionOperating Temperature40 deg C~125 deg C Product DescriptionESP8266 WiFi module is WiFi serial transceiver module, based on ESP8266. Small size and low cost makes it suitable for sensor nodes. It works on 3.3V and consumes current up to 250mA. Current consumption is quite big so it''s usually not powered on battery. If you are using 5V Arduino, then read ESP8266 WiFi and 5V Arduino connection

For arduino board we will use Arduino pro mini 3.3V 8Mhz and software serial port. HW serrial port will be available for program uploading and debugging. Later you can switch module to HW serial port.

Before we start using ESP8266 WiFi module we need to update ESP8266 firmware. We use V0.9.2.2 version of firmware. Detail instructions how to update firmware can be found here. New firmware default baudrate is 9600 which makes possible to use software serial on Arduino board.

ESP8266 current consumption is too big to use Arduino internal regulator. We will use dedicated power regulator AMS1117. Make sure to use big enough additional capacitors to prevent voltage drops when transmitting.

This is WiFi serial transceiver module, based on ESP8266 SoC. This is the ESP-01 VariantThis has an integrated tcp/ip stack 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. The Module Comes with a default AT Firmware. Download the AT Documentation ### This module comes with No Support from us as of the Moment. However There are plenty of Resources Online. So Buy This only if you know what you are getting into

Product Description"NodeMCU" is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The term “NodeMCU” by default refers to the firmware rather than the DevKit. The firmware uses the Lua scripting language. NodeMCU is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266. NodeMCU uses many open source projects, such as lua-cjson, and spiffs.
