Adafruit HUZZAH32 - ESP32 Feather
Overview
The Adafruit HUZZAH32 is a versatile development board featuring the ESP32 dual-core Tensilica LX6 SoC running at up to 240MHz. It integrates Wi-Fi and dual-mode Bluetooth (Classic and LE) into the compact Feather form factor, designed for rapid IoT prototyping. The board includes a built-in Li-Polymer battery charger and an automatic bootloader reset circuit for seamless USB programming.
Why Choose This Part
The HUZZAH32 simplifies power management with a dedicated 3.3V regulator and automatic switching between USB and battery power. Its Feather footprint provides access to 25 GPIO pins, including 12 ADC channels and 2 DACs, while maintaining compatibility with the vast ecosystem of FeatherWing expansion boards.
Applications
Getting Started
To begin development, install the ESP32 board support package in the Arduino IDE or use the Espressif IoT Development Framework (ESP-IDF) via VS Code. Connect the board via a micro-USB cable to utilize the on-board CP2104 USB-to-UART bridge for programming and serial debugging. For mobile applications, plug in a 3.7V Lithium polymer battery to the integrated JST-PH connector.
