Adafruit HUZZAH32 – ESP32 Breakout Board
We have ✅ 1 available of the AF-4172 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Adafruit HUZZAH32 ESP32 Breakout is a compact, breadboard-friendly development board built around the Espressif ESP32 dual-core processor. With WiFi, Bluetooth Classic, and BLE support, 4 MB SPI Flash, and a generous set of GPIO, analog, and communication peripherals, it's a powerful and affordable platform for wireless projects.
This breakout strips the ESP32 down to essentials — a voltage regulator, protection diodes, two buttons, and an LED — without a USB-serial converter or battery charger. Program it via an FTDI cable or CP2104 Friend adapter, then embed it into your project. It ships pre-loaded with ESP32 SPI WiFi co-processor firmware for use with CircuitPython.
