Getting Started
About Arduino ESP32
Welcome to the Arduino ESP32 support documentation! Here you will find important information on how to use the project.
First Things First
Note
Before continuing, we must be clear that this project is supported by Espressif Systems and the community. Everyone is more than welcome to contribute back to this project.
ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth SoC (System On a Chip) designed by Espressif Systems.
ESP32 is designed for mobile, wearable electronics, and Internet-of-Things (IoT) applications. It features all the state-of-the-art characteristics of low-power chips, including fine-grained clock gating, multiple power modes,and dynamic power scaling. For instance, in a low-power IoT sensor hub application scenario, ESP32 is woken-up periodically and only when a specified condition is detected. Low-duty cycle is used to minimize the amount of energy that the chip expends.
The output of the power amplifier is also adjustable, thus contributing to an optimal trade-off between communication range, data rate and power consumption.
The ESP32 series is available as a chip or module.
