For EMC:
•
The
transient voltage suppressor (TR1), enabled by closing JP3, is placed between V
CC
and
GND tracks to protect the
against surge discharge on the supply rail path up to ±1kV/2Ω
coupling;
•
in common mode surge testing, two single-layer capacitors (C1 and C2 - not included) must be soldered at
the predisposed locations;
•
output stages do not require additional EMC protections with respect to the IEC61000-4-2,
IEC61000-4-3, IEC61000-4-5 standards.

Hardware requirements
The
expansion board is designed to be used with the
STM32 Nucleo development boards.
To function correctly, the
must be plugged onto the matching Arduino UNO R3 connector
pins on the
