Adafruit HUZZAH32 – ESP32 Feather Board (Pre-Soldered): Dual-Core Wi-Fi + Bluetooth Development Board

The Adafruit HUZZAH32 – ESP32 Feather Board (Pre-Soldered) is a powerful microcontroller board based on the official ESP32-WROOM32 module, combining Wi-Fi and Bluetooth Classic/LE connectivity in a compact Feather form factor. Featuring pre-soldered headers for instant use, it’s part of the Feather ecosystem, compatible with over 50 FeatherWings to extend functionality for IoT, wireless, and embedded projects.

At its heart is the 240 MHz dual-core Tensilica LX6 MCU with 520 KB SRAM and 4 MB SPI flash, delivering robust performance for multitasking applications. The ESP32 provides extensive peripherals, including multiple UARTs, SPI, I2C, ADCs, DACs, I2S, PWM outputs, and touch interfaces, making it ideal for wireless data logging, control systems, and sensor-based projects. With a built-in USB-to-Serial converter, automatic bootloader reset, and LiPo battery charging, the HUZZAH32 offers developers a seamless prototyping experience.
