SB3
Solder bridge
Solder bridge
X1, 32 KHz crystal for embedded RTC
X2, 8 MHz crystal with socket for STM32L152VBT6 microcontroller, it can be removed
from the socket when an internal RC clock is used.
Reset button B1
Debugging Tools from JTAG connector CN9 and trace connector CN8
Daughterboard from CN7
Embedded ST-LINK/V2
RS-232 connector CN2 for ISP
32 KHz crystal X1 related solder bridges
8 MHz crystal X2 related solder bridges
PH1 is connected to 8 MHz crystal when SB2 is open (default setting).
PH1 is connected to extension connector CN7 when SB2 is closed. In such case
R39 must be removed to avoid disturbance due to the 8 MHz quartz.
PH0 is connected to 8 MHz crystal when SB3 is open (default setting).
PH1 is connected to extension connector CN7 when SB3 is closed. In such case
C30 and X2 must be removed.
PC14 is connected to 32 KHz crystal when SB1 is open (default setting).
PC14 is connected to extension connector CN6 when SB1 is closed. In such
case R37 must be removed to avoid disturbance due to the 32 KHz quartz.
PC15 is connected to 32 KHz crystal when SB4 is open (default setting).
PC15 is connected to extension connector CN6 when SB4 is closed. In such
case R38 must be removed to avoid disturbance due to the 32 KHz quartz.
