5.4 Power
supply
The 32F769IDISCOVERY Discovery board is designed to be powered by the 5 V DC power
supply. It is possible to configure the Discovery board to use any of the following five
sources for the power supply:
•
5 V DC power adapter connected to JP1 (Ext 5 V). In this case, the
32F769IDISCOVERY Discovery board must be powered by a power supply unit or by
auxiliary equipment complying with the standard EN-60950-1: 2006+A11/2009, and
must be Safety Extra Low Voltage (SELV) with limited power capability (5 V power
source on the Ext 5 V silkscreen of JP1). Refer to
Figure 9. ext5V (CN3) from Ext 5 V (JP1)
•
7-12 V DC power from CN11 pin named VIN on silkscreen, the extension connectors
for ARDUINO
®
UNO shields or daughterboards (5 V power source on the Ext 5 V
silkscreen of JP1). The input current capability is linked to the input voltage (Refer to
):
–
800 mA input current when Vin = 7 V
–
450 mA input current when 7 V < Vin (< or =) 9 V
–
250 mA input current when 9 V < Vin (< or =) 12 V
