What have you done with this in the newer versions of the board? Particularly, I see that a fully assembled v2.2 board is available from pico-systems. What is the state of the thermistor readings at room temperature with this version?
I changed the pull-up resistor for the thermistors from 1K to 2K and I removed the diode clamp circuitry. The thermistors are working fine, and are mostly limited by the on-board ADC performance of the BeagleBone. Adding software filtering helps quite a bit.
