I have a 44 year old DIY low voltage lighting system based on TTL circuits that is still going strong. I want to update this system to include smart monitoring.
I have 2 questions.
1) What is the life expectancy of the kc868-a64?
2) What is the duration of your products before they go out if production?

We have designed KC868-A8M (ESP32 CAN Bus Board) for home automation DIYer. it can easy integrate to home assistant by ESPHome. the hardware have 8CH MOSFET output + 8CH digital input + 4CH analog input, support CAN Bus + RS485 + Ethernet + WiFi + Bluetooth + 4G SIM7600 or 2G SIM800L GSM module + DS3231 RTC module + manual control button panel.
Hello everyone ! especially to Hificat... I am developing a project where we are using Lora SX1278 in the KC868-A6 module, according to the characteristics of the Lora the device has a range of 1 km - 5 km, the code used by the sender is the following :
if (LoRaData == "LP01") {
pcf8574.digitalWrite(P0, HIGH);
}
if (LoRaData == "LP00") {
pcf8574.digitalWrite(P0, LOW);
}
}
Serial.print("' with RSSI "); // print RSSI of packet
Serial.println(LoRa.packetRssi());
}
}
I have soldered the antenna on the correct pin and have done some tests, the communication works fine up to 3 meters, but when I move the modules further than 3 meters the communication fails ... maybe you could help me a little, we require a range of more than 200 meters... can you help me and tell me if I'm making a mistake in programming or installing the hardware? Or if I need to buy another Lora module maybe...?
We have designed KC868-A16S (ESP32 16 channel relay board) for home automation DIYer. it can easy integrate to home assistant by ESPHome. the hardware have 16CH relay (MAX AC250V 10A) output + 16CH digital input + 4CH analog input, support RS485 + Ethernet + WiFi + Bluetooth + 4G SIM7600 or 2G SIM800L GSM module + DS3231 RTC module + manual control button panel.
A1/CHA1 is connected to R92
A2CHA2 is connected to R91
A3/CHA3 is connected to R83
A4/CHA4 is connected to R82
It seems that the labelling on the board connectors, shown below, is incorrect.
A1 is connected to GPIO36
A2 is connected to GPIO34
A3 is connected to GPIO35
A4 is connected to GPIO39
Input AA1 is connected to LM224 pin 12
Input AA2 is connected to LM224 pin 10
Input AA3 is connected to LM224 pin 5
Input AA4 is connected to LM224 pin 3
The component labelling of the board matches the corrections that I have made for you on the drawing.
Additionally, you will see that two of the zero ohm resistors on my board, R82 and R83 are open circuit, marked with an X.
Please can you tell me how this can be resolved and provide a link to a correct drawing for my board.
Please can you confirm which GPIO is connected to which Analogue input.
