KC868-A16 ESP32 home automation relay module released! 

The A16 is unique on the market in its price range. Thx was looking so many years for something like this. I want to control many heaters with SSRs in my. Cannot wait to try it.

This A16 is doing well and is very flexible. 16IO Input + 16 IO Relay + etc..... However, for Residential on DIN Board, it is more larger than typical ICT. The Space is not enough to connect Relays cables. MR Kincony, you should reduce the size of the board by 3cm (Height) - In addition the Relay Connectors should be plugged from the front (this will save more space) and not from the bottom part.

For the next board to add SCL SDA and non- used ESP32 ports at the 5V logic level for using both input and output functions. So The board will compitable wide range area according to me . Have a good work🙋‍♂️

Great, please make programming video of it also

It will be wonderful if it has relay outputs but good working 👏👏👏

nice work.....

Can I use Output for AC 12-30V? It will be good use for sprinkler systems.

Hey KinCony, thats a very interesting new release. Can we use the ESP IDF to program the esp32 or should we use the arduino ide only? Do we need to re-flash the ESP32?

can you update the esp module to new ESP32-S3-WROOM-1U ? ESP32 wroom is quite outdated....it will be nice to have a few variants when buying the dev board.....

Is it possible to add RTC to the KC868-A16 ? Or RTC is only available for the bigger KC868-A32 and KC868-A8 ?

Interesting board! Just one question, how can the CH1/CH2 be 0-20mA and CH3/CH4 be 0-5 volt, when looking at the schematic the components are the exact same? Shouldn't all four inputs be able to be 4-20mA or 0-5V?

Could you please confirm KC868-A16 can also run on 24V DC ? We have A32M and run at 24V DC but want to use KC868-A16 for smaller projects.

This time I bought the KC868-A16. If you look at the manual, you can see the rs485 AB terminal. Do I need a module like rs485 TO TTL to connect other controllers modbus communication? Or is it possible to control the KC868-A16 by directly connecting it to the AB terminal of rs485 and connecting it to the controller you want to control?

Hello, can I use the digital inputs to read 12v signals instead of the dry contacts function?

Can I use the output of this board to controll 12v 8 relay module(ordinary 12v 8relay board)….without supplying the 12v input to the outputs…..in normal case using esp32 dev board 5v pin I can power the relay module and switch the relays with using 12v external power supply…how can I use this board to do the same…

Does it connect through the wifi?

How do u address the pins in arduino ide Is it D21 D19 like esp32 dev board

Hi, can this be used to dim(change brightness, ON/OFF) the lights in the room? Does it support multiclicks or longpress button clicks?

Muy bueno, admiro cada vídeo.. soy de Argentina, aquí no tengo idea si se consiguen esas placas, lo cierto es que me gustaría saber donde comprar! Saludos.

Please upgrade the card with CAN bus interface
