The ESP8266 ESP-01 is a compact Wi‑Fi transceiver and self-contained networking module that gives microcontrollers internet access or can run simple web servers and automation tasks on its own, thanks to a 32‑bit Tensilica L106 processor. This 1MB model provides expanded storage for libraries and supports OTA firmware updates, while the integrated TCP/IP stack and preloaded firmware simplify sending GET/POST requests or connecting to MQTT brokers for data logging. Control and flashing are handled over a standard Serial UART interface (RX/TX) using AT commands or a USB‑TTL adapter, and built‑in deep sleep modes drop consumption to micro‑amps for battery‑powered sensor projects. Practical, small, and proven for IoT prototyping and lightweight standalone applications.
