{"title":"Adafruit HUZZAH ESP8266 Breakout","handle":"adafruit-huzzah-esp8266-breakout","url":"/products/adafruit-huzzah-esp8266-breakout","description":"The Adafruit HUZZAH ESP8266 Breakout is a breadboard-friendly WiFi microcontroller board built around the Espressif ESP8266. With an 80 MHz processor, full WiFi client and access point support, a built-in TCP/IP stack with DNS, and a CE/FCC certified module with on-board antenna, it provides an affordable and capable platform for IoT and WiFi projects.\n\nThe breakout includes a 500 mA 3.3V regulator, level shifting on UART and reset pins, two diode-protected power inputs (USB and battery), and an FTDI-compatible pinout for programming via a USB-serial adapter. It ships pre-loaded with NodeMCU's Lua interpreter, and can also be programmed with the Arduino IDE using the ESP8266 core.\n\nKey Features\n\n\nESP8266 at 80 MHz – Full WiFi front-end with client and access point modes\n\nBuilt-in TCP/IP Stack – With DNS support\n\nCE/FCC Certified Module – With on-board antenna\n\n9 GPIO Pins – 3.3V logic, usable for I²C, SPI, or general I/O\n\n1 Analog Input – 1.0V maximum\n\n2 UART Pins – With level-shifted FTDI-compatible pinout for programming\n\n500 mA 3.3V Regulator – With level shifting on UART and reset\n\nDual Power Inputs – Diode-protected for USB cable and battery\n\nReset Button and User Button – User button doubles as bootloader mode selector\n\nRed LED – User-controllable for status indication\n\nNodeMCU Lua Pre-Loaded – Ready to run Lua commands out of the box\n\nArduino IDE Compatible – Install the ESP8266 core and program like any Arduino board\n\n\nIdeal For\n\nWiFi-connected IoT sensor and automation projects\nLow-cost WiFi microcontroller prototyping\nLearning Lua or Arduino programming with WiFi\nEmbedding wireless connectivity into project enclosures\n\n\nPackage Contents\n\n1× Adafruit HUZZAH ESP8266 Breakout – Assembled and tested with NodeMCU pre-loaded\n1× Header strip (unsoldered)\n\n\n\nImportant: A USB-serial adapter is required for programming and is not included. We recommend the FTDI Friend or an FTDI cable.\n\n\n\nNote: The ESP8266 can draw up to 250 mA — budget your power supply accordingly. Light soldering required to attach the included header strip.\n\n\nResources\n\nAdafruit HUZZAH ESP8266 Learn Guide\nUsing with Arduino IDE\nUsing NodeMCU Lua\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":9358,"title":"Default Title","sku":"AF-2471","price":24.23,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":110,"option1":"Default Title"}]}
