This is a board that can transfer your ordinary doorbell (running on 8 - 24v ac) to a wifi doorbell. The board works with an ESP12 ESP8266 module that you can program with a FTDI module and (for example) the arduino IDE. Whenever someone presses your doorbell, the board can execute an action, while leaving the regular doorbell circuit intact, so that if your module crashes for one or another reason, your doorbell will still be working.
I use this board myself to send a MQTT message to my Home assistant whenever the doorbell is pressed, so that home assistant can send a (pushbullet) message to my phone and activate some 433Mhz buzzers in the house. The inspiration for this board came from the Home assistant community, especially from the circuit thought out by user TisGoud, available in the documentation link below.
to program the board, you will need a FTDI module, like this one
To use this board, you'll need to do some programming. The board can be programmed with the Arduino IDE. make sure you have installed the Arduino ide and the ESP8266 arduino core, which you can find in the Design Files link below.
If you click on "source code" at the bottom of this page, you'll find a sample where the board is used to send on/off mqtt messages to home assistant.
Different power supplies can have different polarity. The board is designed for adapters with + on the inside, and - on the outside. Using a different polarity will fry the HT7333 FDO, the board has no protection for this. Look for this sign on your adapter: You can use a adapter with a minimum output voltage of 5v up to a maximum voltage of 12v
I offer a few different versions:
Just the board. You'll have to source the parts yourself and solder it together.
All the parts to solder yourself, the kit does not include the FTDI module or power adapter. I do also offer a kit with 5v adapter, but due to the shipping costs you will be cheaper of buying the adapter from aliexpress yourself.
Fully Assembled and Tested Board
Does not include the FTDI module or power adapter. I do also offer a version with 5v adapter, but due to the shipping costs you will be cheaper of buying the adapter from aliexpress yourself.
This version is your best bet if you don't feel like soldering, all you need to do is program it and you're good to go.

At day-time I'm a freelance IT engineer. In my free time I like to tinker around with electronics, automate my home and toy around with things like LoRaWan. I'm not a professional hardware engineer, but I like to develop, try and test things. Once they come out good (enough), I like to put them on sale here on Tindie so others can enjoy them too.
