Archim2 board - Analog input for PT100 + amplifier board thermistor

I have a TAZ Pro printer that I'm upgrading to print higher temperature materials. I have the PT100 + amplifier board from E3D. I've used this setup previously on a TAZ 6 with a RAMBo board where I plugged the signal wire into an extra analog input pin and changed the pin assignments. Now that the TAZ Pro uses an Archim2.2b board, I'm having a problem finding an open analog input pin from the schematics. Do you know if this is possible to use the PT100 + amplifier board from E3D on the Archim2 boards or if there is a different thermistor that I can plug directly into the thermistor inputs? I'm looking to go up to at least 450C. Thanks.

I’m also curious about this

I don't think they figured it out, but the poster made a second topic where some more info can be found here: [reprap.org]

So I ended up switching to the 450C thermistor from Slice Engineering since I was unable to easily connect to any open analog pins. Another note is that you'll need to purchase two thermistors if you're using a dual printhead and both thermistors need to be the same type. Then you can change the firmware to call out the Slice Engineering thermistor. Hope that helps. Regards, John
