Description
The Arduino
™
Uno V3 connectors (CN13, CN14, CN16, and CN17) are available on the STM32MP157A-DK1 and
STM32MP157C-DK2 Discovery kits. Most shields designed for Arduino
™
can fit with the Discovery kits to offer
flexibility in small form factor applications.
7.16.2
Operating voltage
The Arduino
™
Uno V3 connectors support 5 V, 3.3 V, and VDD for I/O compatibility.
Caution:
Do not supply 3.3 V or 5 V from the Arduino
™
shield. Supplying 3.3 V or 5 V from the Arduino
™
shield could
damage the Discovery kit.
