Power supply

The STM32100B-EVAL board is designed to be powered by a 5 V DC power supply and to
be protected by PolyZen U10 in case of incorrect power supply configuration.
It is possible to configure the evaluation board to use any of the following sources for the
power supply:
●
5 V DC power adapter connected to CN8, the power supply jack labeled "PSU" (for
power supply unit) on the silkscreen.
●
5 V DC power with 500 mA limitation from CN12, the ST-LINK type-B USB connector
labeled "USB" on the silkscreen.
● 5 V DC power from both CN4 and CN5, the daughterboard extension connectors
labeled "DTB" (for daughterboard) on the silkscreen.
The power supply is configured by setting jumpers JP9 and JP10 as described in
Table 2. Power jumpers
Jumper
JP10 is used to select one of the three possible power supply resources.
For power supply from the power supply jack (CN8) to the
STM32100B-EVAL only, JP10 is set as shown:
For power supply from the daughterboard connectors (CN4 and CN5)
to the STM32100B-EVAL only, JP10 is set as shown:
JP10
For power supply from the ST-LINK USB connector (CN12) to the
STM32100B-EVAL only, JP10 is set as shown (default setting):
For power supply from power supply jack (CN8) to both the
STM32100B-EVAL board and to a daughterboard connected on CN4
and CN5, JP10 is set as shown: The daughterboard must not have its
own power supply connected.
V is connected to VDD_MCU power when JP9 is set as shown (default
bat
setting):
JP9
V is connected to battery when JP9 is set as shown:
bat
Risk of explosion if battery is replaced by an incorrect one. Dispose of used batteries
according to the instructions.
To enable MCU power consumption measurement, JP8 and JP12 should be re-configured
as described in Table 3. (PCB rev B only. See
details.)
LED LD5 is lit when the STM32100B-EVAL board is correctly powered by 5 V.
