Thermal measures
To verify the reliability of the design, a thermal mapping by means of an IR camera has been
done.

the key components show the relevant temperature.
between the measured points and the components, for both thermal maps. The ambient
temperature during both measurements was 27°C. According to the results obtained, all the
board components are operating within their temperature limits.
