STM32L152-DISCO

The STMicro STM32L152-DISCO development board provides a developer a low power processor with an LCD segment display,
a user defined button, a capacitive touch slider, two user defined LEDs - green & blue, and an on-board USB ST-Link JTAG interface.
I've been wanting to dive a little deeper with low power devices, and this appears to be rather good development board for that.

Hardware

STM32L152RCT6 low power processor, 32MHz max, with 16KB RAM, 256KB FLASH
Two pushbuttons Black: Reset, Blue: User defined
Four LEDs LD1 (red/green) for USB communication,
          LD2 (red) for 3.3V power
          LD3 (green) user defined
          LD4 (blue) user defined
Capacitive Touch Sensor - Slider / 4 Buttons

On the backside of the development board are pads for a CR2032 coin cell, directions indicate:
"Solder a B7410AP2L battery holder from LOTES on CR1".  (This battery holder appears to be as scarce as hen's teeth.)
