ESP • Basics

What & Why

ESP8266/ESP32 are Wi-Fi (and Bluetooth on ESP32) microcontrollers perfect for IoT: fast, cheap, and power-aware with rich peripherals.

  • Wi-Fi built-in (ESP8266 & ESP32), Bluetooth (ESP32)
  • Many GPIOs with ADC, PWM, I²C, SPI, UART
  • Great for MQTT, REST APIs, OTA updates
  • Arduino Core or ESP-IDF / PlatformIO
