ADAFRUIT INDUSTRIES Feather HUZZAH WiFi Development Board 3.3V 80MHz ESP8266 Microcontroller 2821

ADAFRUIT INDUSTRIES 2821 Feather HUZZAH WiFi Development Board offers a powerful, compact solution for IoT and wireless networking projects with its ESP8266 microcontroller running at 80MHz and 3.3V logic power. This development board is engineered for rapid prototyping and seamless wireless communication using integrated 802.11 b/g/n WiFi.

The board incorporates 4MB FLASH memory (32 MBit) which provides ample space for firmware and application code. It features a Silicon Labs CP2104 USB-to-Serial converter, enabling fast code upload speeds up to 921600 baud rate, significantly improving development efficiency.

Designed with flexibility in mind, the Feather HUZZAH can be powered either by a rechargeable 3.7V Lithium polymer battery or directly via microUSB, which also handles charging with a built-in 100mA LiPoly charger and indicator light. This enables portable and battery-operated use cases for remote or mobile IoT deployments.

Connectivity extends via nine general purpose input/output (GPIO) pins which support multiple communication protocols including I2C and SPI, offering versatile interfacing options with sensors and peripherals. The board also includes one analogue input with a maximum input voltage of 1.0V.

The compact dimensions of 51 x 23 x 8 mm (excluding headers) and light weight of 9.7 grams make it ideal for embedding into tight spaces and mobile devices.

This device complies with RoHS standards and is manufactured in the United States. Adafruit provides extensive support materials to facilitate development with the Feather HUZZAH board, which is popular among hobbyists, educators, and professionals working in electronics, embedded systems, and IoT applications.

The board integrates ESP8266 MCU at 80MHz with 3.3V logic/power for IoT solutions. Equipped with 4MB of FLASH memory (32 MBit) for program storage. Built-in WiFi 802.11 b/g/n enables wireless connectivity. Silicon Labs CP2104 USB-to-Serial converter allows uploads up to 921600 baud rate.
