Evaluation boards
STM32 MCU EVAL boards have been designed as a complete demonstration and
development platform for the Arm
®
Cortex
®
STM32 MCUs.
Figure 6. EVAL board example
They carry external circuitry, such as transceivers, sensors, memory interfaces, displays
and many more. The EVAL boards can be considered as a reference design for application
development.
EVAL boards have integrated ST-LINK (USB Type-B connector). For complete description
of the embedded ST-LINK features refer to
Section 2.1.2: ST-LINK probe.
EVAL board has direct access to JTAG/Traces signal through dedicated Arm
®
JTAG 20-pin
connector allowing advanced debug (ETM). For usage of ETM traces refer to
Section 2.1.3:
Alternative debugger probes on page 19.
The usage of a stand-alone probe may require some jumper and solder bridge adaptation
from default. Refer to the specific board user manual.

STM32 nucleo expansion
STM32 Nucleo expansion boards carry all the required components to Evaluate ST devices
to be used together with an STM32 MCU.
Build STM32-based applications leveraging functionality and performance of ST’s device
portfolio.
The expansion boards are equipped with standardized interconnections, such as an
ARDUINO Uno R3 connector, or a Morpho connector for a higher level of connectivity
Each expansion board is supported by STM32-based software modules.
The combination of STM32 Nucleo boards and expansion boards is a unified scalable
approach with unlimited possibilities for application development, prototyping or product
evaluation.
