Power Supply - ST STM3220F-EVAL User Manual

1.1 Power Supply

STM3220F-EVAL evaluation board is designed to be powered by 5V DC power supply and to
be protected by PolyZen from wrong power plug-in event. It's possible to configure the
evaluation board to use any of following Four sources for the power supply.
■
5V DC power adapter connected to CN18, the Power Jack on the board (PSU on silk
screen for Power Supply Unit).
■
5V DC power with 500mA limitation from CN8, the USB OTG FS Micro-AB connector
(FS on silkscreen).
■
5V DC power with 500mA limitation from CN9, the USB OTG HS Micro-AB connector
(HS on silkscreen).
■
5V DC power from both CN1 and CN3, the extension connector for daughter board
(DTB for Daughter Board on silkscreen).
The power supply is configured by setting the related jumpers JP17, JP18 & JP19 as
described in table 1.
Table 1 Power related Jumpers
Jumper Description
JP17 is used to measure MCU current consumption manually by multi-
meter.
JP17
Default setting: Fitted
JP18 is used to select one of the four possible power supply resources.
For power supply jack(CN18) to the STM3220F-EVAL only, JP18 is set
as shown to the right:
