Description
   The STM32L-DISCOVERY and 32L152CDISCOVERY kits help you to discover the STM32L ultra low power features and to develop and share your applications.
   They are based on an STM32L152RBT6 and an STM32L152RCT6, respectively; and include an ST-LINK/V2 embedded debugging tool interface, an LCD (24 segments, 4 commons), LEDs, pushbuttons, a linear touch sensor or touchkeys.

FEATUREs
• STM32L152RBT6 (128 KB Flash memory,
   16 KB RAM, 4 KB EEPROM) or
   STM32L152RCT6 (256 KB Flash memory,
   32 KB RAM, 8 KB EEPROM) microcontroller in
   an LQFP64 package
• On-board ST-LINK/V2 with selection mode
   switch to use the kit as a standalone STLINK/V2 
   (with SWD connector for
   programming and debugging)
• Board power supply: through USB bus or from
   an external 3.3 or 5 V supply voltage
• External application power supply: 3 V and 5 V
• IDD current measurement
• LCD
   – DIP28 package
