Using a different pull-up voltage for GPIO - xxteh - 12-20-2024
Hello, I am trying to use very long wires to connect multiple DS18B20 sensors to Kincony A16. I can successfully implement the system using Arduino UNO by providing 5V with a 1k pullup resistor and would like to replicate the same thing with Kincony. How can I achieve the same result with Kincony A16 as it only provides 3.3v pull up?

do you will write arduino code for KC868-A16?
or do you want to use KCS firmware with your multi DS18B20 sensors.

Would prefer to write arduino code for A16

it's ok, we have tested before.
here is demo details: https://www.kincony.com/forum/showthread.php?tid=2290

As I am using very long wires, this wiring does not work for my project. I need to externally provide power(voltage) and a different value of pull-up resistor to make this work.
Does the digital pins work like the Arduino's GPIO?

if you want to use for long distance, the best way is chose RS485 sensor.
