6.11 ARDUINO
CN5, CN6, CN8, and CN9 are female connectors compatible with ARDUINO
Most shields designed for ARDUINO
The ARDUINO
For compatibility with ARDUINO
•
SB46 and SB52 must be ON,
•
SB51 and SB56 must be OFF to connect I
Caution 1: The I/Os of STM32 microcontroller are 3.3 V compatible instead of 5 V for ARDUINO
V3.
Caution 2: SB57 must be removed before implementing ARDUINO
