Description

The Adafruit HUZZAH32 ESP32 Feather microcontroller board has a ESP32-WROOM-32 module (Datasheet PDF) that contains the ESP32-D0WDQ6 SoCSystem On a Chip with a 32-Bit Dual-Core 240MHz Xtensa LX6 processor, 4MB SPISerial Peripheral Interface Flash memory chip, and PCBPrinted Circuit Board antenna to provide WiFi (2.4GHz 802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.b/g/n up to 150Mbps) and Bluetooth (v4.2 BRBasic Rate/EDREnhanced Data Rate and BLEBluetooth Low Energy) connectivity.

The board has a Micro-B USB connector for power and data transfer with a CP2104 USB to UARTUniversal Asynchronous Receiver-Transmitter chip that allows your computer to program and communicate with the microcontroller. A 2-Pin JSTJapan Solderless Terminal connector is included so the board can be powered using a 4.2V/3.7V LiPoLithium Polymer/Li-ionLithium-ion battery. There is also battery charging chip, so when the USB is powered, it will automatically switch over to USB for power, as well as start charging the battery (if attached).

User interfaces includes a reset button and 2x LEDLight Emitting Diodes (CHG charge status orange LED and Pin 13 general purpose red LED).

The I/OInput/Output pins are all 3.3V (max) and includes

11x GPIOGeneral Purpose Input Output with PWMPulse-Width Modulation
10x capacitive touch inputs
7x analog inputs (12-bit ADCAnalog-to-Digital Converter (ADC, A/D, or A-to-D))
2x analog outputs (8-bit DACDigital-to-Analog Converter (DAC, D/A, or D-to-A))
Communication interfaces: 3x UARTUniversal Asynchronous Receiver-Transmitter, 2x I2CInter-Integrated Circuit. Also referred to as IIC or I²C., 3x SPISerial Peripheral Interface, 2x I2SInter-IC Sound, and 1x SDIOSecure Digital Input Output (SDIO) is a communication interface that allows devices to connect to an SD card and exchange data..
