Hi everyone, i have a diy core xy printer running on [mks monster8 v2, rpi 3B]  
And i want to add some extra thermistors to chamber (mks has 4, 2 goes for hotend and heatbed).

But i need more so much more.  
I have a mks sgen l, so i’m gonna use that as secondary and i need a few more thermistors but i cant buy klipper expansion module don’t ask why.  
I have one rpi pico and a few esp32.  
Can i connect some ntc thermistor to an esp and configure it with klipper?  
I need 10 thermistor to measure different points in chamber.

Klipper does not support the ESP32 natively. You can flash Klipper and connect thermistors to any MCU listed in `make menuconfig`.

Of course, the provisions to read NTCs, such as a 4.7k pull-up, need to be provided as well. A NTC cannot simply be connected to a free pin.
