PT100 upgrade kit 

The E3D PT100 amplifier board amplifies the signal from the PT100 to a voltage level that your printer controller can read easily and accurately.

Our amplifier board is inspired by the circuit design from the Ultimainboard V2 controller board, but with enhanced filtering for robust and accurate temperature measurement.

This means it’s compatible with temperature sensor '20' in Marlin firmware.
