Product overview
Description
The main objective of the STDES-MB2095 reference design is to provide a board for exploring and demonstrating the different possibilities offered by the STM32U3 series.
The board has a strong educational focus and consists of different, separable parts that can be used as standalone boards. It includes various STMicroelectronics components and can be used on its own or connected to a solderless breadboard, Qwiic boards, or selected SparkFun MicroMod carrier boards.
Using LEDs, a programmable demo displays the built-in sensors in standalone mode and allows control through a USB cable connected to a console application. Programming ARDUINO® and C applications is possible through USB or with an STLINK-V3MINIE debugger (not included).
