ESP32
ESP32 is a low-cost, low-power microcontroller with integrated Wi-Fi and Bluetooth capabilities, developed by Espressif Systems. It is based on the ESP32 microcontroller and can be programmed using the Arduino IDE or the Espressif-IDF. ESP32 is designed for mobile, wearable electronics, and Internet of Things (IoT) applications. It features a dual-core processor, high-speed Wi-Fi, and Bluetooth connectivity, as well as a wide range of peripheral interfaces, including I2C, SPI, UART, and I2S. It is also equipped with a built-in power management system, which allows it to operate efficiently in battery-powered devices.
The ESP32 series of chips includes the ESP32-D0WDQ6, ESP32-D0WD, ESP32-D2WD, and ESP32-S0WD. They are based on the Xtensa dual-core 32-bit LX6 microprocessor and include built-in antenna switches, power amplifier, low-noise receive amplifier, filters, and power management modules. ESP32 is a highly integrated solution for Wi-Fi-and-Bluetooth IoT applications, with around 20 external components. ESP32 is commonly used in Internet of things (IoT) devices, and for building automation and home automation systems.
