The ESP32 is Espressif's Wi-Fi and Bluetooth SoC family for IoT: an MCU with a radio transceiver (Wi-Fi, Bluetooth, Zigbee), which makes it great for connected devices. At about $2 to $5 it is the default prototyping platform for connected hardware.

The ESP32 is Espressif's Wi-Fi and Bluetooth SoC family for IoT: an MCU with a radio transceiver (Wi-Fi, Bluetooth, Zigbee), which makes it great for connected devices. At about $2 to $5 it is the default prototyping platform for connected hardware.

It integrates a dual-core CPU (Xtensa or RISC-V), RAM, flash, the radio and peripheral blocks (ADC, SPI, I2C, PWM).

It is programmed with ESP-IDF (based on FreeRTOS) or with Arduino; the Arduino environment that comes with the board is how many people learn embedded development.

It is popular for smart sensor gateways, home automation and TinyML edge devices.
