Power related jumpers
For power supply from jack (CN12) to the STM32L152-EVAL
only, JP12 is set as shown.
For power supply from daughterboard connector (CN6) to
STM32L152-EVAL only, JP12 is set as shown.
For power supply from USB (CN1) to STM32L152-EVAL only,
JP12 is set as shown.
For power supply from USB connector of ST-LINK/V2 (CN11)
to STM32L152-EVAL only, JP12 is set as shown (default
setting).
For power supply from power supply jack (CN12) to both
STM32L152-EVAL and daughterboard connected on CN6 and
CN7, JP12 is set as shown (daughterboard must not have its
own power supply connected).
VDD is connected to fixed +3.3V DC power when JP13 is set
as shown (default setting).
VDD is connected to adjustable DC power from 1.65 V to 3.6 V
when JP13 is set as shown.
VDD power is directly connected to MCU VDD when JP4 is set
as shown (default setting).
Note: For manual IDD measurement the jumper on JP4 must
be removed and replaced by an ammeter connected between
pin 1 and 2 of JP4.
Connect VDD power to MCU with current-sampling resistor,
1 Ohm or 1 KOhm, in series for IDD current measurement
when JP4 is set as shown.
