Description
The STM32G071B-DISCO Discovery board is a
demonstration and development platform for the
STMicroelectronics Arm® Cortex® -M0+ core-
based STM32G071RB USB Type-C™ and Power
Delivery microcontroller. The STM32G071B-
DISCO Discovery board is presented with all
necessary interfaces for easy connection and
interoperability with other USB Type-C™ devices.
The STM32G071B-DISCO Discovery board is
intended for discovery and display of USB
Type-C™ port characteristics such as data role,
power role, VBUS and IBUS monitoring.
It offers an advanced user mode when associated
with the STM32CubeMonUCPD software GUI
and can be used as a USB Type-C™ and Power
Delivery analyzer.
