32L100CDISCOVERY discovery kit

for STM32L100 Value Line microcontrollers

Introduction

The 32L100CDISCOVERY helps you to discover the features of the STM32L100 Value Line 

32-bit ARM

®

 Cortex™-M3 microcontrollers and to develop your applications easily. It is 

based on STM32L100RCT6 and includes an ST-LINK/V2 embedded debug tool, LEDs, and 
push buttons.
