About ESP8266 boards

The ESP8266 is a low-cost Wi-Fi microcontroller that powered the first wave of affordable IoT projects. These boards range from the bare ESP-01 module to breadboard-friendly dev boards like the Wemos D1 Mini and NodeMCU, all built around the same Tensilica L106 core with integrated 802.11 b/g/n Wi-Fi.

Each listing includes a pinout diagram and the hardware specs you need to pick the right board - flash size, form factor, USB-serial chip and broken-out GPIOs. For newer designs with Bluetooth and more GPIOs, see the ESP32 boards.
