NOTE : BOOT0 is configured as PB8 by default thanks to nSWBOOT0 option bit re-programmed at 0
NOTE : During MCU Reset, PA15 will drive the LED_DOWN_BLUE at low luminance
(thanks to PA15 nternal Pull-up present during T_NRST is low)
USBPD_VIN
Parts above must be close
Parts must be close to MCU.
Resistors must be close to MCU with
very short and symmetric topology :
USB differential pair routed on Top
and/or Bottom ( with GND reference
on L2 / L3). PA11 and PA12 with the
2 resistors with 55ohms single track
R89 resistor to be placed very
T_SWDIO and T_SWCLK must be same
