Adafruit HUZZAH32 – ESP32 Feather Board with Pre-soldered Header

Key Features Module is nestled in at the end of this Feather contains a dual-core ESP32 chip ESP32 has way more GPIO than the ESP8266 Recommended for makers who have some experience with microcontroller programming. Pre-assembled headers Aww yeah, it's the Feather you have been waiting for, this time with pre-assembled headers! The HUZZAH32 is Adafruit's ESP32-based Feather, made with the official WROOM32 module. Packed with everything you love about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and just about all of the GPIOs brought out so you can use it with any of the Feather Wings. This version of the ESP32 Feather comes with plain 0.1" headers already soldered in so  its ready for instant gratification and Feather fun!The ESP32 is a perfect upgrade from the ESP8266 that has been so popular. In comparison, the ESP32 has way more GPIO, plenty of analog inputs, two analog outputs, multiple extra peripherals (like a spare UART), two cores so you don't have to yield to the WiFi manager, much higher-speed processor, etc. etc!Item Specifics240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPSIntegrated 520 KB SRAMIntegrated 802.11b/g/n HT40 Wi-Fi transceiver, baseband, stack and LWIPIntegrated dual mode Bluetooth (classic and BLE)4 MByte flash include in the WROOM32 moduleOn-board PCB antenna10x capacitive touch interface32 kHz crystal oscillatorPWM/timer input/output available on every GPIO pinOpenOCD debug interface with 32 kB TRAX bufferSDIO master/slave 50 MHzSD-card interface support3 x UARTs3 x SPI2 x I2C12 x ADC input channels2 x I2S Audio2 x DACSize: 50.0mm x 23.0mm x 15.6mm / 2.0" x 0.9" x 0.6"Weight: 8.4g / 0.3ozLipoly battery and USB cable not included
