ESP8266 and ESP32 Boards

ESP8266 and ESP32 development boards break out the pins of Espressif's WiFi and Bluetooth modules onto breadboard-compatible headers, adding a USB-to-serial chip for direct programming from a computer. They are the quickest way to start building wireless IoT projects without custom PCB work.

The range includes the NodeMCU ESP8266 and ESP32, Wemos D1 Mini, ESP32 DevKit V1, ESP32-S2, ESP32-S3, and ESP32-C3 boards, as well as specialty variants with integrated displays, batteries, or LoRa radios.

These boards are used to prototype home automation devices, wireless sensor nodes, MQTT clients, BLE peripherals, web-served dashboards, and data loggers. They are a staple component in Singapore's maker and IoT engineering community, used in schools, hackathons, and commercial product development alike.
