Pin define and pcb

[XaLex2]

Hi there!
 Your products are very interesting and quite comfortable in use but finding technical data about product is utterly frustrating
   Could you make it clear, what pins on mcu are corresponded to the upper side? I mean where are the temperature sensors pins on pcb? There is not the place which is the only where I can find all the data about product. I have to get through all your webite, to find any info pice by pice: picture with pinout is on home page, schematic diagramm is on absolutely different page, pins defines is on the forum. And all of this info conflicts to each other. 
 

  where is the temp sensor inputs on the picture? Why  in the description   it's sad there are only two analog inputs, but on the picture and pcb i can see 4 ones? What are the io-1 and  io-2 on the picture of the board? Are they temp sensor input? ok, but why they have absolutely different name wich aren't somewhere else? why is all the info so inconsistent?

  And why dont't you place all the information related to product the right on the product page?

here is schematic of KC868-A6 , i think this is useful for you know all details:
https://www.kincony.com/download/KC868-A6-schematic.pdf

all our board schematic can download from https://www.kincony.com/document

Thanks for your suggestion, we will update all information links on one webpage.

temperature sensor you can connect to "IO-2" and "IO-1". These two GPIOs have pull-up resistance. such as connect with DS18B20 or DHT11/21/22 temperature and humidity sensor. Actually you can use multi DS18B20 senosr with one GPIO.

A1-A4 is 4 channel analog input ports. 2 channel: analog input DC 0-5v , 2 channel: analog 4-20mA

A1,A2,A3,A4 .. wich are DC 0-5V? and wich are 4-20 mA ?

I thinks all are DC 0-5V ...

this the KC868-A6 board default all are dc0-5v, if you want to use by 4-20mA, just need to replace two resistance is ok. do you want to use 4-20mA sensor?

Yes i Want to use 4-20mA.. can i have info how to replace resistance?

Thanks

if you don't want to use dc 0-5v sensor , want to use 4-20mA sensor, for example, A1 replace with R15=0 ohm resistance , R20 replace with 150R  resistance.
every analog input channel can modify as the way.

Hi,
I am trying to use the HT1 as a PWM signal pin. Is the pin number 8 as in the schematic?
TIA

Also pin number for HT2 and HT3. Thanks.

HT1,HT2 use for 1-wire device, such as DS18B20 temperature sensor , WS2812 LED strip.
HT1 is GPIO32, HT2 is GPIO33. you can see the diagram: https://www.kincony.com/download/KC868-A6-schematic.pdf
whether can use for PWM, you need to check with ESP32-WROOM-32E datasheet.

Tested in MicroPython to work for all 3 pins with PWM. Thanks.

ok, good.
