Figure 18. ST morpho connector pinout
Note: Arduino Uno V3 D0 and D1 signals are connected by default on USART1 (MCU I/O PA9
and PA10). Refer to
Section 9.9: Virtual COM port: LPUART1/USART1 for details about
UART interface modification.
10.4 External power connector
The external power connector CN11 is an 8-pin, single-row, 2.54 mm-pitch connector. By
default this connector is not soldered. The PCB footprint gives the possibility to easily
control the V
core
logic and the V
DD_MCU
power supply with an external source. The external
power connector is showed in
Figure 19.
