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. For more information regarding how to set up the amplifier board please see our documentation page.
The PT100 amplifier board requires a controller board that is running Marlin or Repetier with a spare analogue input pin.
