Product overview


The STM32G081B-EVAL Evaluation board is a high-end development platform, for Arm Cortex-M0+ core-based STM32G081RBT6 microcontroller, with USB Type-C and power delivery controller interfaces (UCPD), compliant with USB type-C r1.2 and USB PD specification r3.0, two I2Cs, two SPIs, five USARTs, one LP UART, one 12-bit ADC, two 12-bit DACs, two GP comparators, two LP timers, internal 32 KB SRAM and 128 KB Flash, CEC, SWD debugging support.

The full range of hardware features on the STM32G081B-EVAL Evaluation board includes a mother board, a legacy peripheral daughterboard and a USB-C and Power Delivery daughterboard, which help to evaluate all peripherals (USB Type-C connector with USB PD, motor control connector, RS232, RS485, Audio DAC, microphone ADC, TFT LCD, IrDA, IR LED, IR receiver, LDR, MicroSD card, CEC on two HDMI connectors, smart card slot, RF E2PROM & Temperature sensor…), and to develop applications.

The board integrates an ST-LINK/V2-1 as an embedded in-circuit debugger and programmer for the STM32 MCU.

The daughterboard and extension connectors provide an easy way to connect a daughterboard or wrapping board for the user's specific applications.

The USB-C and Power Delivery daughterboard features two independent USB-C ports controlled by an STM32G0. USB-C port 1 is dual role power (DRP) and can provide up-to 45 W. USB-C Port 2 is sink only. Both support USB PD protocol and alternate mode functionality.

Application firmware examples are provided to evaluate the USB-C technology through various use cases.
