Adafruit HUZZAH32 ESP32 Breakout Board

Squeeeeze down your next ESP32 project to its bare-bones essential with the Adafruit HUZZAH32 Breakout. This breakout is the 'big sister' of our HUZZAH 8266, featuring the ESP32 chip. It is a pared-down version of the popular Feather ESP32, removing the battery charger and USB-serial converter to keep size and price to a minimum.

The board includes a regulator, protection diodes, two buttons, and an LED. It requires an external USB-to-serial converter such as a CP2104 Friend or FTDI cable to program. To upload code, hold down GPIO #0 button and click Reset, then release GPIO #0 to enter bootloader mode.

The ESP32 module includes a dual-core, 240 MHz Tensilica LX6 microcontroller with 600 DMIPS, 4 MB SPI Flash, integrated WiFi (802.11b/g/n HT40), Bluetooth Classic and BLE support, an onboard PCB antenna, ultra-low noise analog amplifier, hall sensor, capacitive touch interfaces, multiple UARTs, SPI, I2C, ADC channels, DAC outputs, PWM/timer IO, and more.

This board comes fully assembled and tested, ready to use. Headers are included for easy soldering and breadboard compatibility.
