Datasheet

Please note: The ESP32 is still targeted to developers. Not all of the peripherals are fully documented with example

code, and there are some bugs still being found and fixed. We got all of our Featherwings working under Arduino IDE,

so you can expect things like I2C and SPI and analog reads to work. But other elements are still under development.

For that reason, we recommend this Feather for makers who have some experience with microcontroller programming,

and not as a first dev board.

Here are specifications from Espressif about the ESP32 (https://adafru.it/wew)

240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPS

Integrated dual mode Bluetooth (classic and BLE)

4 MByte flash

On-board PCB antenna

Ultra-low noise analog amplifier

Hall sensor

10x capacitive touch interface

32 kHz crystal oscillator

3 x UARTs (only two are configured by default in the Feather Arduino IDE support, one UART is used for

bootloading/debug)
