Product description
The ESP8266 development board combines the popularity of the Arduino environment with WiFi functionality for wireless projects. The integrated microcontroller and WiFi module are already mounted on a single slim DIP-format board, with no need to install additional components. A total of 32 pins are available for controlling sensors or actuators, including several for analog measurements.
Programming is performed with the Arduino IDE, without the need for specialized software. Sketches are uploaded via USB. The 3.3 V operating voltage must be taken into account when wiring sensors or modules with 5 V logic, as a level shifter must be connected in this case. The module stores programs and data itself, eliminating the need for a separate EEPROM.
The board is suitable for temperature monitoring with sensor networks, remote control of lights or switches, collecting data from environmental sensors with WiFi upload, and simple web servers running directly on the board. One specific scenario is monitoring the indoor climate of multiple rooms, with each board reading a local sensor and transmitting the measurements to a central server.
Operation requires a USB power supply or a power adapter with a capacity of at least 500 mA. The Arduino IDE must be extended with the ESP8266 board package. WiFi range depends on local conditions. Neighboring networks or heavily shielded rooms limit practical usability.
Safety information
The module operates with 3.3 V logic levels. Connections to 5 V circuits require a level shifter to prevent damage. The board is intended exclusively for building prototypes and for testing and development purposes and is not suitable for installation in the household electrical system. If anything is unclear before commissioning, consult a qualified electrician.
