ESP32ESP8266
ESP32 and ESP8266 are families of Wi-Fi system-on-chip microcontrollers developed by Espressif Systems. They provide built-in wireless connectivity for embedded devices and have become popular in the Internet of Things (IoT) due to low cost, small form factors, and a wide development ecosystem. The ESP8266 introduced a compact, single-chip solution with integrated 802.11 Wi‑Fi, while the ESP32 family followed with more processing power, additional wireless options, and expanded peripherals. The ESP32 lineup includes several variants such as ESP32-D0WD, ESP32-S2, ESP32-S3, ESP32-C3 (RISC-V), and others, each targeting different balance points between performance, power, and features.
The ESP8266 is a low-cost, single-core microcontroller that runs at up to 80 MHz (with some modules
The ESP32 adds substantial enhancements: a faster Xtensa dual-core or single-core architecture (up to 240 MHz
