This ESP8266 ESP-12F development board combines Wi-Fi control with eight onboard relays for embedded automation, remote switching, and control-panel prototypes. Module I/O and the UART programming interface are broken out for firmware development.
Board Features
- ESP-12F Wi-Fi module with listed 4MB flash.
- Eight onboard 5V relays controlled through two 74HC595 shift registers.
- DC 7-28V input or regulated 5V power input.
- UART programming header, reset button, programmable button, power indicator, relay indicators, and onboard status LED.
- Reference development support for Arduino IDE and other ESP8266 toolchains.
Relay Outputs
The source lists relay contact ratings up to AC 250V or DC 30V and 30A under specified conditions. Actual allowable load depends on contact type, duty cycle, inrush current, PCB terminal limits, wiring, enclosure, cooling, and applicable electrical standards; derate the load appropriately.
Package Contents
- 1 x ESP8266 eight-channel relay module.
- 1 x 22-pin header strip.
- 1 x jumper cap.
Safety Note
Keep low-voltage logic isolated from hazardous-voltage wiring. Mains installation should be completed only by a qualified person using a suitable enclosure, fusing, grounding, wire gauge, strain relief, and clearances.
