What voltage range can I power the A4 board with? I am using LifePO4 battery with a voltage range of 11v - 14.7v. Is this OK?

Hi, what is the thickness of the traces between the load connector and the relay? Is the trace only on the bottom layer of the pcb or on bottom, top and inner layers (if there are any)? I'm trying to assess how much current the traces can actually handle.

Hi, 
I am about to order the KC868-A16 for my project and just wanted to check if its really gonna work.
Is it possible to do HTTP requests over ethernet cable and GET or SET the state of on input//output?

There are many examples online where the ESP32 is used as a webserver, which one can send HTTP requests in order to trigger GPIOs on or off, would that also work with KC868-A16?

With my setup I need to control the KC868-A16 with a custom app that communicates oder HTTP, I cannot use the webinterface that may be present in the device.

Thanks in advanced, 
Romano

Hello!
I have read a lot of information here and website and I want to clarify and understand the capabilities of the KC868-D16 for lighting control.
What are the capabilities of KS868? 

1. Successfully dims LED strip at 12V,
2. Successfully dims 220V normal light bulb.
3. It dims with flickering LED dimmable bulbs 220V.

What are the options for dimming the RGBW LED strip, and color changing? 

Here is the answer from the email:
"Is the dimmer controller able to manage RGB LED lights, ( stripe)?
answer: any of our ESP32 boards have GPIOs support WS2812B RGB LED stripe."

WS2812B RGB LED stripe needs 5V power suply.

Sorry, if this is not the exact place for this post.

Hello, i have a strange case here. I am running ESPhome with the KC868-A8 board with Ethernet and i want to use a second KC868 board. On the second board the ethernet port is not working and i don't have access to a WiFi signal. Is there a way to communicate with the first board and send and receive data without connecting it to wifi or ethernet ?

Thanks

Fix the card using pin 22 (nRF24L01 CE) and connect it with DI01 (view image)

   

Now the configuration in the project is as follows:

// Pin mapping
const lmic_pinmap lmic_pins = {
  .nss = 5,                                                                                             // byte 0: pin for select
  .rxtx = LMIC_UNUSED_PIN,                                                               // byte 1: pin for rx/tx control
  .rst = 21,                                                                                           // byte 2: pin for reset
  .dio = { /*dio0*/ 2, /*dio1*/ 22, /*dio2*/ LMIC_UNUSED_PIN },       // bytes 3..5: pins for DIO0, DOI1, DIO2
};

.....

SPI.begin(18, 19, 23, 5);  // These specific pins are for kc868-a6
if (os_init_ex((const void *)&lmic_pins)) {

Hi,

I would like to use on digital strip led with the board A8S V2.
How can I manage that ?
Do I  need to install ESPHome ?
Is it quite esay to configure ?
Can I use the digital strip and the relay together ? ( I Don't know ESPHome but I will learn)

Thanks !
