Hi, i am building a 3d printer that needs to go up to 450c/500c.... I have a pt100 sensor and a signal amplifying board, now I know how to assign 5v/ground and a pin to the board on a ramps/radds to make a hi-temp printer, but I am completely lost on how to add a pt100 sensor on the panda board. if somebody could help me out a little with the wiring it would mean a lot to me. Thank you!

Check your wiring, and contact Mark Niu if you don't have success. The PT100 is in PandaPi, but I see no wiring examples for the PandaPi Board.
6 inputs from a stepper driver and 2 or 4 for the pt100, but i cannot get it to work i have done everything a couple of times and nothing seems to work, sensor might be broken.... any new sugestions are welcome
I see no example on the PandaPi site, so I refer you to Adafruit's Product No. 3328 which is the MAX31865 Amplifier for the PT100 Sensor. I do not know if we are allowed to put URLs in our posts, so I will refrain. You should be able to find it easily. It will require six inputs to the MAX31865, and four inputs for the PT100.
Thank you for your response. How would i go about the wiring ? do i just plug in the pt100 as i would a normal thermistor or do i have to connect the signal boosting board (5v/ground/signal) or MAX31865 board ? how would i go on about wiring one or another ? does the panda pi have a MAX31865 input ? where i can just plug the pt100 and just change the code ?
In the Thermal Settings section of Marlin, you can there is a table with the various sensors that you can use. PT100 / PT1000 is the first one in the table with a value of "-5".
* Temperature sensors available:
* -5 : PT100 / PT1000 with MAX31865 (only for sensors 0-1)
* -3 : thermocouple with MAX31855 (only for sensors 0-1)
* -2 : thermocouple with MAX6675 (only for sensors 0-1)
Simply change the sensor number(s) in the appropriate lines to the proper sensor. In your case, change the 13 to -5.
