Hardware Modifications
======================
Analog Frontend
---------------
.. note::
Solder a ``100 nF`` capacitor parallel to ``R315`` in order to implement a low pass characteristic of the difference amplifier in the :ref:`analog frontend<hw_analog_fe>`. This massively increases EMI performance which prevents the :ref:`ADC Watchdog<firmware_meas_adc_watchdog>` from triggering.
Power Supply
------------
.. note::
Replace transformer ``BV-EI-303-2010`` with ``BV-EI-303-2050``, which has the same footprint but a little more power and does not heat that much.

Although the Shimatta Reflow Controller provides a bunch of safety mechanisms that prevent your house from burning down, NEVER leave the oven controller running unattended.
