Evaluation board with STM32G081RB MCU
Introduction
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 32KB SRAM and 128KB Flash,
CEC, SWD debugging support.
The full range of hardware features on the STM32G081B-EVAL Evaluation board includes
the mother board, the legacy peripheral daughterboard and the USB Type-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, smartcard
slot, RF E2PROM and temperature sensor… etc.) and to develop applications. An ST-
LINK/V2-1 is integrated on the board as 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 your specific application.
The USB Type-C and Power Delivery daughterboard features two independent USB-C ports
controlled by STM32G0. USB-C port 1 is dual role power (DRP) and can provide up-to 45W
of power. USB-C Port 2 is sink only. Both supports USB PD protocol and alternate mode
functionality.
