IOT Module using ESP-12F
ESP-12F based IOT module which will give 5V / 9V outputs from five digital pins of ESP-12F. 5V outputs can be used to control TTL / CMOS ICs. Output will be 5V if the jumper is conncted across COM and 5V. Similarly, output will be 9V if the jumper is connected across COM and Vin. You can control your devices like electric bulbs from Android applications through this module. Screw terminal output interfacing is also provided for 5V / 9V digital outputs.
