STM32 Discovery kits are a cheap and complete solution for the evaluation of the outstanding capabilities of STM32 MCUs and MPUs. They carry the necessary infrastructure for demonstration of specific device characteristics and comprehensive software examples allow to fully benefit from the devices features and added values.  

Extension connectors give access to most of the device’s I/Os and make the connection of add-on hardware possible.

With the integrated debugger/programmer the discovery kits are ideal for prototyping.
