ESP8266 16-channel relay module for 12 V projects

This ESP8266 WIFI 16 channel relay module uses an ESP-12F development board to provide sixteen independently switched channels. It is aimed at hobbyists and engineers building mains-level automation or IoT control systems that run from a 12 V supply. The board integrates Wi-Fi connectivity so each relay can be triggered remotely without additional networking hardware.

Limited to 12 V supply and sixteen channels

The module operates only from a 12 V power source and cannot be used with higher or lower voltages without external regulation. Its sixteen relays set a hard ceiling on the number of switched circuits; applications needing more channels require additional modules. Wi-Fi range and throughput depend on the local environment and the ESP8266 radio, so very large installations may need wired alternatives.
