Power supply

The STM320518-EVAL evaluation board is designed to be powered by a 5V DC power

supply and to be protected by PolyZen from incorrect power plug-in events.

It is possible to configure the evaluation board to use any of the following three sources for

the power supply.

●

5V DC power adapter connected to CN15, the power jack on the board (power supply

unit (PSU) on the silk screen). External power supply is not provided with the board.

●

5V DC power with 500 mA limitation from CN13, the USB type B connector of ST-

LINK/V2 (USB 5 V power source (STlk) on silkscreen).

●

5V DC power from CN6, the extension connector for daughterboard (daughterboard

power source (D5V) on silkscreen).

The power source is selected by setting the related jumpers JP8 as described in Table 3.

Description

JP8

JP8 selects one of the three possible power supply resources.

For the power supply jack (CN15) to STM320518-EVAL only,

JP8 is set as shown:

For power supply from the daughterboard connectors (CN6) to

STM320518-EVAL only, JP8 is set as shown:

For power supply from USB (CN13) of ST-LINK/V2 to STM320518-

EVAL only, JP8 is set as shown (default setting):

For power supply from the power supply jack (CN15) to both

STM320518-EVAL and daughterboard connected on CN5 and CN6,

JP8 is set as shown (the daughterboard must not have its own power

supply connected):
