Discovery kits with STM32L152RCT6

and STM32L152RBT6 MCUs

Introduction

The STM32L152RCT6 Discovery kit (32L152CDISCOVERY) and the STM32L152RBT6

(STM32L-DISCOVERY) allow to develop applications based on the STM32L1 Series and to

benefit from the ultra-low-power features of these microcontollers.

The 32L152CDISCOVERY is based on an STM32L152RCT6 (256 Kbytes of Flash

memory). The STM32L-DISCOVERY is based on an STM32L152RBT6 (128

Kbytes of

Flash memory).

These discovery kits include the ST-LINK/V2 in-circuit debugger, one LCD (24 segments, 4

commons), four LEDs, two pushbuttons, one linear touch sensor and four touchkeys.
