Product details

Overview

STM32G071B-DISCO from STMicroelectronics is a USB Type-C™ and Power Delivery (PD) development board built around the STM32G071RBT6 microcontroller (Arm® Cortex®-M0+, 128 KB Flash, 32 KB RAM, LQFP64), featuring an on-board 128×64 OLED display, dual USB Type-C™ interfaces (plug & receptacle), three isolated current/power monitors (VBUS, CC1, CC2), and integrated ST-LINK/V2-1 debugger with mass storage and Virtual COM port support.

For engineers reviewing the STM32G071B-DISCO datasheet, STM32G071B-DISCO pinout, STM32G071B-DISCO application, or STM32G071B-DISCO equivalent, this board serves as a functional USB Type-C™ PD analyzer and evaluation platform-supporting real-time VBUS/IBUS monitoring, role negotiation testing, and UCPD protocol analysis when used with STM32CubeMonUCPD GUI software.

Technical Context

The board implements full USB Type-C™ dual-role port functionality using the STM32G071RB's native UCPD peripheral, enabling hardware-level detection of data/power roles, VCONN control, and CC line voltage/current measurement via dedicated analog front-end circuitry. It supports USB PD 3.0 message exchange through firmware-driven UCPD transceivers.

Power architecture includes an on-board DC/DC converter accepting 3–20 V input (±5 %) from either ST-LINK VBUS or external USB Type-C™ source, delivering regulated 3.3 V to MCU and peripherals. All critical USB Type-C™ signals-including CC1, CC2, VBUS, SBU1/SBU2-are accessible via test points and extension headers for signal integrity validation.

Key Specifications

Parameter	Value and Actual Design Meaning
MCU Core	Arm Cortex-M0+ @ 64 MHz - deterministic real-time execution for USB PD state machine and UCPD protocol handling
Flash / RAM	128 KB Flash / 32 KB SRAM - sufficient for dual-role PD stack + GUI logic + USB device class firmware
OLED Display	128 × 64 pixels, SPI interface - local visualization of power role, VBUS voltage, CC line status, and PD contract details
Current Monitoring	3-channel isolated I²C ADC - measures VBUS, CC1, and CC2 currents up to ±3 A with 10-bit resolution for PD compliance verification
Debug Interface	ST-LINK/V2-1 over Micro-AB USB - provides JTAG/SWD debug, virtual COM port, and mass storage programming without external tools
Power Input Range	3 V to 20 V (±5 %) - enables testing across USB PD voltage profiles (5 V, 9 V, 15 V, 20 V) with single-board operation
User I/O	4-way joystick + reset button + 4 status LEDs - direct interaction for mode selection, reset, and visual feedback of USB Type-C™ configuration states

FAQ

Does STM32G071B-DISCO support USB PD 3.0 sink and source negotiation?

Yes. The board implements full dual-role port capability using the STM32G071RB's UCPD peripheral and preloaded firmware. It supports PD 3.0 structured VDMs, explicit contract negotiation, and role swapping (DRP) when paired with STM32CubeMonUCPD software and a compliant host or sink device.

Can the on-board ST-LINK/V2-1 program other STM32 targets?

Yes. The ST-LINK/V2-1 interface is fully compatible with all STM32 microcontrollers supported by STM32CubeProgrammer and OpenOCD. It exposes SWD pins via the 8-pin user extension connector and can be used as a standalone debugger for external STM32 boards without modifying the Discovery kit hardware.

Is the OLED display directly driven by the MCU or via a separate controller?

The 128×64 OLED module uses a SSD1306 controller and communicates exclusively via SPI with the STM32G071RB. All display initialization, pixel mapping, and text rendering are handled in firmware using ST's HAL drivers and STM32CubeMX-generated initialization code.

What operating systems are supported for STM32CubeMonUCPD software?

STM32CubeMonUCPD is officially supported on Windows 7/8/10, 64-bit Linux distributions (Ubuntu 18.04+, Debian 10+), and macOS 10.14+ (Mojave and later). USB CDC ACM enumeration requires no additional drivers on Windows 10 and recent macOS versions.
