Hi, I have some questions regarding the KC868-A16 board, please answer as follows:

1. I have a INPUT signal which is either connected to (common) GND or 5V. Will the inputs recognize this correctly?

2. I have an actor, type 1 (OUTPUT) which supports 5V and needs to be connected to GND when switched. Will this work?

3. I have an actor, type 2 (OUTPUT) which will need 15V output. Will this voltage be okay (instead of 12V)?

1. latch mode: Button1

    on_press:
      then:
      - switch.toggle: e16s_output1


2. inching mode: Button2

    on_press:
      then:
      - switch.turn_on: e16s_output2
    on_release:
      then:
      - switch.turn_off: e16s_output2 


3. momentary mode: Button3

    on_turn_on:
    - delay: 1000ms
    - switch.turn_off: e16s_output3


4. interlocking mode: Button4-Button5

interlock: [e16s_output5]

interlock: [e16s_output4]

Are there any plans to add TWAI (CANBUS) controler e.g.with SN65HVD23x instead of RS-232/RS-485? 

With CANBUS it's easy to daisy-chain any number of boards whereas RS-232/RS-485 are tricky to add more than just 1 additional board. 
I would preffer setup with several smaller boards - e.g. 4-6 relays/inputs and ability to add more when needed rather than aiming for maximum planned IOs.

Please add comments if anyone else would be ineterested in it.

To enable the USB 2.0 ports on the Compute Module 4, you need to edit the boot config file (/boot/config.txt) and add:

dtoverlay=dwc2,dr_mode=host
Then reboot the Pi. Now you should be able to use the built-in USB 2.0 ports!

Hello,

I have no success to read data from RS485 port (orange one). I use NODE-RED for building flows.

To make sure that it is not issue in any configuration I used USB->RS485 adapter and I had success to read data.

There are two serial available when execute

1. /dev/ttyS0
   
2. /dev/ttyAMA0
   

1. get the MQTT feedback message from every puch button.

2. create "automation" for buttons in home assistant.

Dear kincony Custmer support,
I bought 4 pieces of this module to connect them to varies function
1. External for learn the remote control of garage gate motor to open close by mobile app the same application for all.
2. Another to control reception 3 Air conditions remote control + home appliances of living room:-
DVD
VIDEO
OUTDOOR AMPLIFIER
PROJECTOR
HOME THEATER
SATELLITE RECIEVER
BLURAY
SMART TV
APPLE TV 

All in the same room and all work with remote control
Bearing in mind the 3 AC split AC are the same remote and code for all 3 unit and i need to control each separate from mobile app.
3. Master bedroom AC, TV, Satelite reciever, shutter motor using Wifi SONOFF
4. Multi purpose room Bluray 4 K, smart TV, XBox, home theater reciever.
Please send me clear procedures and you tube videos for installation and vsries programing related toeach function above..
Thanks in advance

I also noticed sometimes UART is disabled in kernel. The enable it you need to check in /boot/config.txt the line enable_uart

If it's set to 0 like follow

enable_uart=0
You need to change to 1 as follow

enable_uart=1
And reboot of course!

sudo raspi-config
   
make sure disable Linux UART console
