Espressif's Wi-Fi + Bluetooth SoC family targeting IoT.

Espressif's Wi-Fi + Bluetooth SoC family targeting IoT.

Integrates dual-core CPU (Xtensa or RISC-V), RAM, flash, radio, and peripheral blocks (ADC, SPI, I2C, PWM)

Programmed via ESP-IDF (FreeRTOS-based) or Arduino.

Popular for smart sensor gateways, home automation, and TinyML edge devices.

Low cost (~$2-5); the default prototyping platform for connected hardware.

MCU + Radio Transceiver (includes Wifi, Bluetooth, Zigbee); great for IoT.

Arduino (comes with the PCB) is used to learn embedded development.
