{"title":"Adafruit HUZZAH32 – ESP32 Breakout Board","handle":"adafruit-huzzah32-esp32-breakout-board","url":"/products/adafruit-huzzah32-esp32-breakout-board","description":"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.\n\nThis 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.\n\nKey Features\n\n\nESP32 Dual-Core 240 MHz – Tensilica LX6 with 600 DMIPS and 520 KB SRAM\n\n802.11b/g/n WiFi – Integrated transceiver with on-board PCB antenna\n\nBluetooth Classic and BLE – Dual-mode wireless connectivity\n\n4 MB SPI Flash – WROOM32 module with tuned antenna\n\nRich Peripherals – 3× UART, 3× SPI, 2× I²C, 2× I²S, 2× DAC, 12× ADC channels\n\n10 Capacitive Touch Inputs – Built-in touch sensing\n\nHall Sensor – On-chip magnetic field detection\n\nPWM on Every GPIO – Flexible output control\n\n3.3V Regulator – With protection diodes\n\nFTDI-Compatible Pinout – Program via FTDI cable or CP2104 adapter\n\nCompact Form Factor – Breadboard-friendly with minimal extras for size-constrained projects\n\n\nIdeal For\n\nWiFi and Bluetooth IoT projects at minimal cost and size\nEmbedding wireless connectivity into custom enclosures\nCircuitPython WiFi co-processor applications\nUpgrading from ESP8266-based projects\n\n\nPackage Contents\n\n1× Adafruit HUZZAH32 ESP32 Breakout – Assembled and tested with ESP32 SPI WiFi firmware pre-loaded\n1× Header strip (unsoldered)\n\n\n\nImportant: A USB-serial adapter is required for programming and is not included. Use a CP2104 Friend or FTDI Friend. To enter bootloader mode, hold GPIO #0, click Reset, then release GPIO #0 before uploading code.\n\n\nResources\n\nAdafruit HUZZAH32 ESP32 Learn Guide\nCircuitPython ESP32SPI Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6880,"title":"Default Title","sku":"AF-4172","price":27.53,"on_sale":false,"in_stock":true,"available_quantity":101,"option1":"Default Title"}]}
