Description

The Adafruit HUZZAH32 Feather Board leverages the certified ESP32-WROOM32 module, providing a complete, FCC-certified wireless solution in the compact Feather form factor. Its dual-core LX6 microcontroller delivers 600 DMIPS of processing power, efficiently handling complex IoT tasks and wireless protocol stacks simultaneously. The board includes a tuned PCB antenna, ultra-low noise analog amplifier, and comprehensive power management with an integrated single-cell LiPo charger, making it ideal for field-deployed sensor nodes and portable devices.

Designed for developer convenience, the HUZZAH32 features pre-configured Arduino IDE support, with multiple peripheral interfaces (3x UART, 3x SPI, 2x I2C) brought out to standard 0.1″ headers. Its low-power architecture supports deep sleep modes, while the 10 capacitive touch GPIOs enable innovative human-interface designs. The combination of robust wireless connectivity, ample 4 MB flash, and the extensive Feather Wing ecosystem makes this board a versatile foundation for prototyping Wi-Fi/Bluetooth connected systems, from smart home controllers to industrial telemetry gateways.

Frequently Asked Questions

How do I program the Adafruit HUZZAH32 ESP32 Feather Board?

The board is pre-configured for the Arduino IDE. Install the ESP32 board support via the Boards Manager using the Adafruit or Espressif repository URL. Select 'Adafruit ESP32 Feather' as your board. The built-in USB-to-serial converter and auto-reset circuit allow you to upload code directly via the micro USB port without manual button presses. For advanced use, you can also program it using ESP-IDF or MicroPython via the serial bootloader.

What is the power supply range and how do I use a battery?

The HUZZAH32 operates at 3.3V logic. You can power it via the micro USB port (5V) or through the dedicated LiPo battery JST connector. The on-board charging circuit manages single-cell LiPo/Li-ion batteries (3.7V nominal). Connect a battery to the JST port; it will charge when USB is connected. The board automatically switches to battery power when USB is disconnected, making it seamless for portable applications. Monitor battery voltage via the analog pin connected to the voltage divider.

Are all GPIO pins available and what are their special functions?

Most GPIOs from the ESP32-WROOM32 are broken out to the Feather headers, but some have default functions. Pins 0 and 2 are used for bootloading. Pins 32-39 are ADC inputs on ADC1. Pins 25 and 26 are DAC outputs. Ten pins (4, 12-15, 27, 32-33, etc.) support capacitive touch sensing. Three hardware UARTs are available, though UART0 is used for programming/debug. Refer to the Adafruit pinout diagram to identify usable pins for SPI, I2C, PWM, and avoid strapping pins that affect boot mode.
