STMicroelectronics STM32G474E-EVAL1

Overview

STM32G474E-EVAL1 from STMicroelectronics is a motor-control configuration evaluation board built around the STM32G474QET6 Arm® Cortex®-M4 microcontroller (512 KB Flash, 96 KB RAM, LQFP128), featuring dual CAN 2.0A/B ports, on-board STLINK-V3E debugger, 240×320 TFT LCD with SPI interface, and dedicated motor-control expansion connectors.

For engineers reviewing the STM32G474E-EVAL1 datasheet, STM32G474E-EVAL1 pinout, STM32G474E-EVAL1 application, or STM32G474E-EVAL1 equivalent, this board supports rapid prototyping of real-time motor control, USB FS device firmware development, audio codec integration via SAI, and analog sensor signal conditioning using integrated op-amps and comparators.

Technical Context

The board implements a full-featured hardware reference for STM32G474QET6-based motor control systems, integrating dual CAN transceivers, configurable RS-232/RS-485 interfaces, and two sets of motor-control expansion headers compatible with three-phase inverter gate drivers. It supports real-time debugging via ETM trace and SWD/JTAG over STDC14 and TAG footprints.

Power architecture includes flexible sourcing (ST-LINK VBUS, USB Type-C®, or external supply), adjustable MCU core voltage (1.62–3.60 V), and on-board current measurement circuitry enabling closed-loop current sensing validation. The 8-Mbit SRAM and dual 512-Mbit Quad-SPI NOR Flash support high-speed code execution and firmware storage.

FAQ

What distinguishes STM32G474E-EVAL1 from STM32G474E-EVAL?

The STM32G474E-EVAL1 is a motor-control configuration board, featuring two dedicated motor-control expansion connectors with routed PWM outputs, ADC inputs, and gate-driver enable signals-unlike the base STM32G474E-EVAL, which lacks these specialized headers and targets general-purpose evaluation. Both share the same STM32G474QET6 MCU and core peripherals.

Does STM32G474E-EVAL1 support CAN FD?

No-STM32G474E-EVAL1 integrates two standard CAN 2.0A/B-compliant transceivers only. The STM32G474QET6 MCU itself does not include a CAN FD controller; CAN FD capability requires the STM32G484 or higher-series MCUs, such as those on the STM32G484E-EVAL board.

Can the on-board STLINK-V3E program external STM32 targets?

Yes-the STLINK-V3E on STM32G474E-EVAL1 supports external target programming via its 10-pin STDC14 debug footprint and TAG connector. It delivers SWD/JTAG signals, 3.3 V target power (configurable), and VTREF sensing, enabling reliable flashing and debugging of other STM32 boards without additional tools.

Is the 240×320 TFT LCD module resistive or capacitive?

The on-board 240×320 TFT color LCD module uses a resistive touch overlay, compatible with the STM32G474QET6's FSMC or LTDC peripheral depending on configuration. Touch functionality is accessed via dedicated GPIO lines and ADC channels-not through I²C or SPI, confirming its resistive implementation per ST's UM2514 user manual.
