Power supply

The STM32303E-EVAL evaluation board has been designed to be powered by 5 V DC
power supply and to be protected by PolyZen from wrong power plug-in event. The
evaluation board can be configured to use any of the four following sources of power supply:
• 5 V DC power adapter connected to CN14, the power jack on the board (Power supply
unit (PSU) on silkscreen of JP14). The external power supply is not provided with the
board.
• 5 V DC power with 500 mA limitation from CN5, the USB type B connector of ST-
LINK/V2 (USB 5 V power source on silkscreen of JP14 ( STlk)).
•
5V DC power with 500mA limitation from CN12, the USB type B connector (USB 5V
power source on silkscreen of JP14 (USB)).
•
5V DC power from CN6 & CN7, the extension connectors for daughter board (daughter
board power source on silkscreen of JP14 (D5V)).
The power s4upply is configured by setting the related jumpers JP14, JP15, JP16 and JP17
as described in Table 2.

JP14 is used to select one of the four possible power supply resources.
For power supply from the daughter board connectors (CN6 and CN7) to
STM32303E-EVAL only, JP14 is set as shown to the right:
For power supply from USB (CN12) to STM32303E-EVAL only, JP14 is set as
shown to the right:
For power supply jack (CN14) to the STM32303E-EVAL only, JP14 is set as
shown to the right:
For power supply from USB connector of ST-LINK/V2 (CN5) to STM32303E -
EVAL only, JP14 is set as shown to the right (default setting):
For power supply from power supply jack (CN14) to both STM32303E -EVAL and
daughter board connected on CN6 and CN7, JP14 is set as shown to the right
(the daughter board must not have its own power supply connected):
Vbat is connected to the battery when JP16 is set as shown to the right:
Vbat is connected to VDD power when JP16 is set as shown to the right (default
setting):
