Overview
Power supply (JP1, JP3)
The STM8L15LPBOARD is powered by a lithium battery CR2032 when jumper JP3 is
closed.
Depending on the JP1 position, the MCU consumption auto-measurement circuit can be
used.
Table 1.
LCD glass (R26, C12)
The STM8L15LPBOARD drives a 4-mux LCD glass SBLCDA2. The LCD voltage reference
VLCD is shorted to VDD with a 0 ohm resistor (R26).
The internal LCD voltage reference embedded in the STM8L15LPBOARD can be used
when R26 is removed. R26 is located on the bottom side of the board.
A I µF capacitor C12 is connected to VLCD for internal booster usage.
SWIM connector (CN3)
A SWIM connector CN3 is available for programming and debugging.
Buttons (PC0, PC1)
Two buttons with wakeup interrupt capability are available.

External quartz (PC5, PC6)
A 32.768 kHz quartz is connected to LSE pins PC5 and PC6. It can be used either as the
RTC clock, or to run the CPU.

JP1 setting
PC1
VDD power is directly connected to MCU VDD when JP1 is set as shown to the left
(default setting).
Note: For manual IDD measurement the JP1 jumper must be removed and replaced
by an ammeter connected between pin 1 and 2 of JP1.
Connect VDD power to MCU with current-sampling resistor (2 ohm or 2 Kohm) in
series for current measurement when JP1 is set as shown to the left.
