Description

Adafruit HUZZAH32 is a new development board from Adafruit with a built-in WiFi ESP32 module. The heart of the board is the ESP32 module with a microcontroller clocked at 240 MHz and logic working in the voltage range from 0 to 3.3 V. The programming of the board is extremely simple thanks to the Arduino IDE environment providing a quick start for projects related to IoT technology.

Attention!
The microcontroller lines tolerate the 3.3V voltage. Applying higher voltage to these lines can damage the microcontroller.

Built-in lithium-polymer battery connector and charger module enable connection of a 500 mAh Li-Pol battery . The battery is charged via the mounted USB connector. In addition, the board has a connection between the battery and one of the analog inputs, which allows detecting the battery charge and battery discharge signaling. The board has soldered goldpin connectors (there is also a version without soldered connectors - Adafruit HUZZAH32 - Feather module with Wi-Fi ESP32 )
