The PT100 amplifier board amplifies the signal from the PT100 to a voltage level that the printer controller can easily and accurately read.
This amplifier board is inspired by the circuit design of the Ultimainboard V2 controller board, but with an advanced filter for robust and accurate temperature measurement. This means it is compatible with the '20' temperature sensor in the Marlin firmware. For more information on how to set up the amplifier board, see our documentation page.
Please note:
The PT100 amplifier board requires a controller board running Marlin or Repetier with a spare analog input pin.
