Description

Adding Internet connectivity to your project with ease and at a lower cost. The circuit ESP8266 from expressive is a microcontroller running at 80 mHz with a wireless (client and Access Point) with a layer of TCP/IP and DNS support. Although this tour is very popular, it is quite difficult to implement, these low cost modules lacks integrated controller and are diffile to be implemented on a breadboard, this version HUZZAH reegle this concern.

Adafruit HUZZAH ESP8266 Breakout module has been designed to make the circuit ESP8266 easy to use for more fun. It is from a certified ESP8266 CE module assembe and FCC with a built-in antenna, a regulator 3, 3V 500mA and a lot of pine trees are out. In addition, we find:

• A Reset button
• A user button which can be used to switch mode bootloading
• A configurable red LED
• An adaptation of levels for UART and Reset signals
• A regulator 3, 3V 500 my (the ESP8266 requires only 250mA)
• A protection diode in the power supply (USB and battery)

At the level of the pines (compatible breadboard), we find:

• 1 X input analog (max 1, 8V)
• 9 X GPIO in logic i2C or SPI 3, 3V usable
• 2 X UART pins
• 2 X power pins 3-12V, Reset, Enable, Disable LDOS, output 3, 3V.

A connector to the output of the module is compatible with the FTDI, ideal to program and debug the module pinout.

Each module comes pre-loaded with the Node - MCU LUA Interpreter. So you can use it directly with a simple USB-serial cable. The module is sold assembled and welded with a connector strip 1 X 36 not welded.

Features 

• "Dimensions: 25mm x 38mm x 5mm / 1"x 1.5"x 0.2"
