STM32G071B-DISCO

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.
