Adafruit Feather HUZZAH with ESP8266 – Loose Headers

Link your electronics to the web with the Feather HUZZAH ESP8266.

Standard WiFi modules can be difficult to power and program. However, this Feather HUZZAH provides an all-in-one professional solution. It uses the popular ESP8266 chip with a built-in USB-to-Serial converter. Consequently, you can upload your code directly without extra cables.

Key Features:

• 80MHz Processor Speed: It features a fast and reliable microcontroller. Because of this, it handles web requests and sensor data smoothly.

• Integrated LiPoly Battery Charging: The board includes a 3.7V Lithium polymer charging circuit. Therefore, it is perfect for portable or remote projects.

• Compact Feather Factor: It measures only 51mm x 23mm x 8mm. Furthermore, it fits perfectly into small cases or wearable electronics.

• Large Community Support: It offers full compatibility with the Arduino IDE. Simply use existing libraries to connect to MQTT or web servers.

Why should you choose this WiFi board? Are you building a smart thermostat or a remote weather station? Because of its “plug-and-play” design, you save hours of complicated wiring. Moreover, it includes 9 GPIO pins and an analog input for your sensors. Furthermore, it features an onboard reset button for easy debugging. Therefore, it is the best choice for fast IoT prototyping. Simply connect it to your computer via micro-USB to begin.
