Product Description

ARM STM32 Board STM32 DISCOVERY STM32L152RBT6 needing STM32L-DISCOVERY # Open32L-D Standard

 

STM32 development board designed for the ST official tool STM32L-DISCOVERY, and integrates various standard interfaces, pretty easy for peripheral expansions.

STM32L152RBT6 development board

Overview

Open32L-D is an STM32 development board designed for the ST official tool STM32L-DISCOVERY, which features the STM32L152RBT6microcontroller onboard.

The Open32L-D supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with STM32L series microcontrollers.


What\'s on the mother board

STM32L152RBT6 development board on board resource
  1. STM32L-DISCOVERY socket: for easily connecting the STM32L-DISCOVERY
