I'm looking at the hardware diagram trying to find what pins could I use for DS18B20 sensors.
The white serial port is I2C and it seems that's already in use for the Mosfets. Seems that GSM and other ports already have IC's connected to them.
Please would you share pins that are directly connected to the ESP32 so I could use for One-Wire protocol to read the DS18B20 ?
I have two sensor buses each with 6 sensors so Ideally I need to use 2 Pins. Attached a picture of the board.
Thank you,

KC868-A32M no free GPIOs to use. if you MUST need to use DS18B20, i think you can use the 4G module socket, if the RXD,TXD pin not used , you can add a pull up resistance, then connect with DS18B20 sensors.
