STMicroelectronics STM32G081B-EVAL Evaluation Board

STMicroelectronics STM32G081B-EVAL Evaluation Board is a high-end development platform designed for Arm^® Cortex^®-M0+ core-based STM32G081RBT6 microcontrollers. The STM32G081RBT6 microcontrollers offer 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 STM32G081B-EVAL Evaluation Board features a full range of hardware options including a motherboard, a legacy peripheral daughterboard, and a USB-C and Power Delivery daughterboard. These contribute to evaluating all peripherals such as 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 STM32G081B-EVAL integrates an ST-LINK/V2-1 as an embedded in-circuit debugger and programmer for the STM32 MCU. The USB-C and Power Delivery daughterboard features two independent USB-C ports controlled by an STM32G0 as an easy way to connect a daughterboard or wrapping board for the user's specific applications.
