Здравствуйте! Прошу прислать пример скетча на Arduino IDE для контроллера KinCony KC868-A6
Датчик сухого контакта подключен к цифровому входу DI-1 и GND в контроллере KinCony KC868-A6.
При замыкании сухого контакта Реле 1 включается
При размыкании сухого контакта Реле 1 выключается
Напряжение на контакте DI-1 составляет 11 В. Это нормальное напряжение?

Hello,

I want to measure the presence of current on a 220 V device (≤16 A) using my KC868‑A6.

I have a 20 A ACS712 current sensor (analog output 0–5 V). I plan to use Arduino code directly. Before connecting it, I would like to know:

1. Are the analog inputs (ADC) of the KC868‑A6 (GPIO 36/39/34/35) compatible with a signal from a 20 A ACS712 when using Arduino code?
   
2. Is any filtering or signal conditioning required to ensure the ADC reads it correctly?
   
3. Are there any special precautions regarding ground or reference to get a reliable reading?
   

Hi everyone,
I'm seeking some technical advice on reviving an A6 v1.3 board (ESP32-based).
The situation: The board was running ESPHome perfectly. However, following a Wi-Fi AP migration and some "beginner mistakes" within Home Assistant, I’ve lost all connectivity to the device.
The problem:

• No OTA: Since the Wi-Fi credentials are now incorrect, I cannot access it over the air.
  
• Serial flashing fails: I am unable to upload new firmware via the onboard USB port.
  
• Hardware status: The onboard USB-to-Serial chip seems functional (it's recognized by the OS), but there is zero communication with the ESP32 SoC itself. It won't enter bootloader mode or accept any flash commands.
  

1. Is there a way to "force" this specific board into flash mode if the auto-reset circuit is failing?
   
2. Can I bypass the onboard serial chip and flash the SoC directly using an external FTDI programmer? If so, does anyone have the pinout for the RX/TX/IO0/EN pads on this v1.3 board?
   
3. Are there any specific recovery tools or "low-level" utilities (besides esptool.py) that you would recommend to "wake up" a non-responsive ESP32?
   

Hi Gerarding model F8 N16R8 . There are have UART pin ?

Hi everyone,
I am building a lighting control system for about 170 mini incandescent bulbs.
Load

• Bulbs: 6V, 0.2A each
  
• Total: ~170 bulbs
  

1. Is this the correct wiring method for KC868-A32M outputs?
   
2. Can these MOSFET channels support PWM dimming for incandescent bulbs, or only ON/OFF?
   
3. What is the best way to control multiple KC868-A32M boards from a PC (LAN/MQTT/Modbus)?
   
4. Any important power or wiring concerns for a 170-bulb system?
   
   

Hello,

I have contacted administration multiple times, no result. That is why posting here.

Please delete my account on this forum.

Thank you.

I need ~50 CT inputs, can I chain multiple M30 boards via the bus header on the board?

Hi im new user
I knew that  "KCS" firmware is not an open source .
so its up on your developers to consider adding a way to implement selfe edited dash board on the   KC868 itself
im sure it will be A large jump on your firmware

Problem Summary
I cannot get network registration on my KC868-A16S board. The modem consistently returns CSQ=99 (No Signal) and fails to attach to GPRS.
________________________________________
Hardware Setup
• Board: KC868-A16S (ESP32 with integrated GSM module)
• SIM Card: Active SIM with data plan (tested working in phone)
• Antenna: LTE antenna connected to the antenna port
• Power: 12V DC power supply

Software Configuration
Platform
• PlatformIO with Arduino framework
• ESP32 Dev Module target
• TinyGSM library v0.11.7
Pin Configuration (from our code)
// GSM Module Pins
#define PIN_GSM_RX 32  // ESP32 receives from modem
#define PIN_GSM_TX 33  // ESP32 sends to modem
#define PIN_GSM_PWR 23 // Power pin (unused currently)
APN Settings
#define APN_NAME "internet"
#define APN_USER ""
#define APN_PASS ""
________________________________________
Initialization Code
// GSM Modem Init
SerialAT.begin(115200, SERIAL_8N1, PIN_GSM_RX, PIN_GSM_TX);
delay(3000);
Serial.println("Initializing GSM modem...");
modem.restart();
// Check Signal Quality
int csq = modem.getSignalQuality();
Serial.print("Signal Quality (CSQ): ");
Serial.println(csq);
// Wait for Network
if (!modem.waitForNetwork(15000)) {
    Serial.println("Network registration FAILED");
} else {
    Serial.println("Network OK");
    // Connect to GPRS
    if (!modem.gprsConnect(APN_NAME, APN_USER, APN_PASS)) {
        Serial.println("GPRS Connect failed");
    }
}
________________________________________
Serial Monitor Output
Initializing GSM modem...
Signal Quality (CSQ): 99
Waiting for network... FAILED (will retry in loop)
Network lost. Reconnecting...
Network unreachable
CSQ=99 means "Not Detectable" according to AT command specifications.

What I Have Tried
1. ✅ Verified SIM card works in mobile phone
2. ✅ Tried different APN names ("internet", "")
3. ✅ Checked antenna connection
4. ✅ Tried baud rates: 9600, 57600, 115200
5. ✅ Power cycled the board multiple times
6. ❓ Not sure if there is a PWR_KEY or RESET pin that needs toggling
________________________________________
Questions for KinCony Team
1. What is the GSM module model on the A16S? (SIM7600, SIM800L, A7670C, or other?)
2. Are the TX/RX pins correct? (We use GPIO 32 for RX, GPIO 33 for TX)
3. Is there a power-on sequence required? Does the GSM module have a PWR_KEY or RESET pin that must be toggled before use?
4. What baud rate should we use? (Currently 115200)
5. Do you have a working demo code or .bin file that we can flash to verify the hardware works?
________________________________________
Additional Information
• Wi-Fi connection works perfectly on the same board
• All other I2C devices (PCF8574, RTC, sensors) work correctly
• The board was purchased recently and appears undamaged
