Description
This single-channel WiFi relay module integrates an ESP-12F module with a heavy-duty 30A relay for wireless switching. Designed for flexible power input between 7V and 28V or direct 5V, it allows remote control of high-current loads. It is ideally suited for makers, students, and hobbyists building connected IoT automation systems.
High-current relay switching
The board features an onboard 5V, 30A single-channel relay capable of managing loads within AC 250V or DC 30V ranges. This provides reliable switching capacity for high-power electrical appliances and circuits.
ESP-12F development platform
Powered by the mature ESP-12F WiFi module with 4MB of flash memory, the board breaks out all I/O and UART programming ports for easy secondary development. It is compatible with popular development environments such as Eclipse and standard IDEs.
Onboard controls and indicators
The board includes an RST reset button, a programmable user button, and a programmable LED on the ESP-12F module. Dedicated status indicators for board power and relay activation provide immediate visual feedback.
