Product details
Overview
STM32G081B-EVAL from STMicroelectronics is a full-featured evaluation board for the STM32G081RBT6 Arm® Cortex®-M0+ microcontroller (128 KB Flash, 32 KB SRAM, LQFP64), featuring dual USB-C ports with Power Delivery (up to 45 W DRP on Port 1), RS-232/RS-485 interfaces, stereo audio jack with microphone ADC, microSD™ slot, and on-board ST-LINK/V2-1 debugger supporting mass storage, VCP, and SWD.
For engineers reviewing the STM32G081B-EVAL datasheet, STM32G081B-EVAL pinout, STM32G081B-EVAL application, or STM32G081B-EVAL equivalent, this board supports rapid prototyping of USB-C PD systems, motor control, industrial HMI, and multi-interface embedded applications with validated hardware abstraction layers in STM32Cube.
Technical Context
The board implements a modular architecture: a mainboard hosting the STM32G081RBT6 MCU with configurable 1.65–3.6 V supply, RTC with backup battery, 12-bit ADC, two 12-bit DACs, and five USARTs; plus interchangeable daughterboards - one for legacy peripherals (IrDA, LDR, temperature sensor, HDMI CEC, smart card) and one for USB-C/DP/USB PD (dual Type-C ports, DisplayPort alternate mode, VCONN, 19 V PD input).
ST-LINK/V2-1 is integrated as an in-circuit debugger/programmer with USB re-enumeration (mass storage, virtual COM port, debug port), enabling seamless firmware development across Keil®, IAR™, and GCC-based IDEs on Windows®, Linux®, and macOS®.

FAQ
Does STM32G081B-EVAL support USB Power Delivery sink and source modes simultaneously?
Yes - USB-C Port 1 operates as a dual-role port (DRP) compliant with USB PD 3.0, capable of sourcing up to 45 W or sinking power dynamically based on policy engine execution on the STM32G081RBT6. Port 2 is sink-only. Firmware examples in STM32Cube demonstrate real-time role swapping and voltage/current negotiation.
Can the legacy peripheral daughterboard be used independently of the USB-C daughterboard?
Yes - both daughterboards connect via dedicated edge connectors to the mainboard and are electrically isolated. The legacy board (IrDA, LDR, temperature sensor, HDMI CEC, smart card) functions fully without the USB-C board installed, and vice versa. Each uses separate power domains and GPIO mappings.
What software tools are officially supported for firmware development on STM32G081B-EVAL?
ST officially supports Keil® MDK-ARM, IAR™ EWARM, and GCC-based IDEs (including STM32CubeIDE). All are validated with the board's ST-LINK/V2-1 interface and STM32CubeG0 HAL/LL libraries. Preloaded demonstration firmware runs standalone and source code is available on www.st.com.
Is the ST-LINK/V2-1 on STM32G081B-EVAL field-upgradable?
Yes - the embedded ST-LINK/V2-1 firmware can be updated via USB using ST's official STSW-LINK007 utility. This enables compatibility with newer STM32 devices and debugging features without hardware modification, and supports mass storage drag-and-drop programming and virtual COM port logging out-of-the-box.
