This is a WiFi Dimmer board which has esp8266-12E/12F (node MCU) and Atmega328p, Triac (normally open), One Triac for Speed control/Dimming .It also has an on board 100-230VAC to 5VDC converter. Can be programmed for Mqtt. USB- uart Converter on board so can directly be programmed based like nodemcu and arduino uno
Note:With Current Code there is some flicker more suited for fan than bulb, code link provided .Any improvement suggestion plz let us know
Input Supply :100-240VAC Output Relay :2A 240VAC NO(Normally Open) Triac : BT136 Esp Model:12E/12F Atmega328p On board 3V3 regulator Programming: Through USB -arduino or lua
If you are considering buying this item, you probably already know all this but in the interest of your safety, we feel compelled to state all this clearly. So take a few minutes to read it carefully before buying.
AC mains are very dangerous -- Even a 50 V AC supply is more than enough to kill you.
Please Switch off the mains before making or changing connections, be very very careful.Ifyour are not sure of anything related to the Ac supply linesplease call an electrician ask him to help you our with it .
Do not attempt to interface to mains unless you have adequate training and access to appropriate safety equipment.
Never work on high voltages when you are alone by yourself. Always ensure that you have a friend/partner who can see and hear you and who knows how to quickly turn off power in case of an accident.
Use a 1A Fuse in series with the input to the board as a safety measure.
Basic Wiring diagram is available on our instructables page and github .Please go through it
Fire Hazard: Making wrong connections, drawing more than rated power, contact with water or other conducting material, and other types of misuse/overuse/malfunction can all cause overheating and risk starting a fire. Test your circuit and the environment in which it is deployed thoroughly before leaving it switched on and unsupervised. Always follow all fire safety precautions.**
