KC868-A16 ESP32 home automation relay module released!

[@GeldVerdienenOnline1]

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.

[@KinCony]

thanks, you can chose dc12v SSR connect with A16

[@adil_daoudson]

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.

[@KinCony]

thank you for your suggestion.if only use PCB board, connector plugged from front is very good, just now many people will use plastic case, the cable only can connected at bottom part.

[@ersheikismail8293]

Great, please make programming video of it also

[@KinCony]

in furture will do it.

[@gok_dogan]

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

[@KinCony]

thanks for your suggestion.

[@gok_dogan]

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🙋‍♂️

[@KinCony]

thanks for your suggestion. A16 and A8 already have IIC of SCL and SDA ports. maybe can place the free INPUT , OUTPUT IO for 5v level in furture.

[@Cabinlab]

The data sheet for the mosfet says they are rated up to 60V and 10A. Since they have a separate power input, is it possible to use them for the higher rated DC voltage? For example: 48VDC

[@KinCony]

MAX support 30V DC by board, because other circuit IC support MAX30VDC, if you want use one power supply for all .

[@alexsahka5472]

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

[@KinCony]

sorry, MOSFET only use by DC.

[@LucaCalcaterra]

I bought this, just arrived. Any way to connect to a 5v relay board (already owned and wired) ? Or , in alternative , i can buy a 12dc board optoisolated on amazon ?

[@KinCony]

if you MUST want use 5v relay board, need voltage convert circuit module.

[@nikhuge6580]

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 ESP32 wroom is quite outdated....it will be nice to have a few variants when buying the dev board.....

[@KinCony]

you can replace by yourself, but not sure whether pin2pin compatible.

[@nikhuge6580]

@@KinCony can u give me the link to pcb design files? I would like to try..

[@KinCony]

@@nikhuge6580 it's open source, we will upload schematic of circuit.

[@lau586]

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

[@KinCony]

no problem

[@charlesrg]

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

[@KinCony]

ESP32 have RTC inside, do you want use a extender RTC module? if yes, ok, we have i2c RTC module, you can connect with A16 board's i2c extender.

[@smartteg7381]

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

[@KinCony]

yes , define by GPIO number.

[@charlesrg]

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.

[@KinCony]

sure, A16 support dc12-24v

[@ChrisFredriksson]

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?

[@KinCony]

The resistance values on different channels are different, which is used to adapt to different types of sensors of 0-5V or 4-20mA

[@michalzachar409]

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

[@KinCony]

yes, use for dimmer, it can change brightness. whether support multi click, just set config yaml file by esphome.

[@michalzachar409]

@@KinCony what did you meant by use for dimmer? i was told that kc868-a16 cannot dim the lights

[@michalzachar409]

@@KinCony so can it change brightness of the light or no?

[@KinCony]

@@michalzachar409 A16 can connect with addressable LED strip, such as WS2812B LED

[@KinCony]

@@michalzachar409 if common light, A16 can't use for change brightness. if you connect with WS2812B RGBW LED strip, no problem.

[@nikhuge6580]

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…

[@KinCony]

yes, you can use A16 work with your 12v relay board. just connect A16 Vin with dc12v of the output terminal, there is a "COMMON" Vin for load.

[@nikhuge6580]

@@KinCony what happen if I didn’t supply the 12v to 8 output channel common vin pin…….and try to switch on off the relays…

[@KinCony]

@@nikhuge6580 will be no voltage output, because KC868-A16 is mosfet output, no relay on the board.

[@7GIGEO7]

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?

[@KinCony]

both can use arduino and ESP IDF, not need to re-flash, just directly to use.

[@7GIGEO7]

@@KinCony Awesome, will be getting this along with A4 version for some field testing. Thanks.

[@KinCony]

@@7GIGEO7 you are welcome

[@andrewprzygoda]

Does it connect through the wifi?

[@KinCony]

both support wifi and ethernet.

@@KinCony hi. And thanks for your reply. I have purchased one a few hours ago on aliexpres. Can you advise me how to get a Tuya license? Thanks

thanks.

[@chill2night2sdaymars13]

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?

[@KinCony]

not need RS485-TTL, just connect to device with A and B. do you let A16 board work as "MASTER" or "SLAVE"? do you write arduino IDE code or use ESPHome?

[@santydesalta6089]

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.
