STMicroelectronics' 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 MCU. The STM32G071B-DISCO discovery board offers the necessary interfaces for easy connection and interoperability with other USB Type-C devices. The discovery board is intended for discovery and display of USB Type-C port characteristics such as data role, power role, VBUS, and IBUS monitoring.
The STM32G071B-DISCO discovery kit offers an advanced user mode when it is associated with the STM32CubeMonUCPD software GUI enabling it to be used as a USB Type-C and power delivery analyzer.
