Power supply
The STM8L1526-EVAL is designed to be powered by a 5 V DC power supply and to be
protected by PolyZen from a wrong power plug-in event. It is possible to configure the
evaluation board to use any of following three power supply sources.
1.
The power supply is configured by setting the related jumpers JP1, JP2 and JP11 as
described in
Table 1.

JP11
Jumper
5 V DC power adapter connected to CN2, the power jack on the board (power supply
unit (PSU) on silk screen).
5 V DC power with 500 mA limitation from CN11, the USB type B connector for ST-
LINK (ST-link on silkscreen (STL)).
5 V DC power from CN10, the extension connector for daughterboard (daughterboard
power source (DTB) on silkscreen).
JP2 selects one of the three possible power supply resources.
For power supply jack(CN2) to the STM8L1526-EVAL only, JP2 is set as shown
to the right.
For power supply from the daughterboard connectors(CN10) to STM8L1526-
EVAL only, JP2 is set as shown to the right.
For power supply from ST-LINK connector (CN11) to STM8L1526-EVAL only,
JP2 is set as shown to the right (default setting).
For power supply from power supply jack (CN2) to both STM8L1526-EVAL and
daughterboard connected on CN4 and CN10, JP2 is set as shown to the right
(daughterboard must not have its own power supply connected).
VDD is connected to fixed +3.3 V DC power when JP1 is set as shown to the
right (default setting).
VDD is connected to adjustable DC power from 1.65 V to 3.6 V when JP1 is set
as shown to the right.
VDD power is directly connected to MCU VDD when JP11 is set as shown to
the right.
Note: For manual IDD measurement the jumper on JP11 must be removed and
replaced by an ammeter connected between JP11 pin 2 and pin 3.
Connect VDD power to MCU with current-sampling resistor, 2 ohm or 2 Kohm,
in-series for IDD current measurement when JP11 is set as shown to the right
(default setting).
