I just want to confirm which ports are 4mA-20mA and which are 0-5V.. according to description in here https://www.kincony.com/arduino-esp32-16...ule-2.html analog input port 1 (pin36)&2(pin34) are 4mA-20mA.. and 3(pin 35)&4(pin 39) are 0-5V.., correct? At the same time in the schematic drawings https://www.kincony.com/download/KC868-A...ematic.pdf all analog input ports are marked as 0-5V which makes me confused.
The background of the question is that I'm trying to connect temperature sensor from Danfoss which operates in a range of 9-32VDC power supply and 4mA-20mA as a output signal. I connected one wire from sensor to +12VDC & the other one to port 1 (pin 36) and readings of sensor is around 950 out of 1023 (10 bits resolution) for 30C which is obviously way to much (sensor range is 0-200C so I'm expecting something around ~300). Any ideas what might be wrong?
