Product details

Overview

STM32L476G-EVAL from STMicroelectronics is an evaluation board for the STM32L476xx ultra-low-power Arm® Cortex®-M4 MCU with FPU, featuring 1 MB Flash, 128 KB SRAM, USB OTG FS, LCD controller, and integrated SMPS support. It enables rapid prototyping of battery-powered IoT sensors, portable medical devices, and energy-harvesting endpoints requiring sub-µA standby operation and rich analog/peripheral integration.

For engineers reviewing the STM32L476G-EVAL datasheet, STM32L476G-EVAL pinout, STM32L476G-EVAL application, or STM32L476G-EVAL equivalent, this page delivers verified technical context, key specifications, availability details, manufacturer background, and targeted FAQ - all grounded in ST's official DS10198 Rev 11 documentation and board user manual UM1811.

Technical Context

The STM32L476G-EVAL board hosts the STM32L476VGT6 MCU (LQFP100 package), a fully functional member of the STM32L476xx family. It provides direct access to all 82 GPIOs, dual ADCs (5 Msps), two 12-bit DACs, LCD segment driver (4×44), capacitive touch sensing (24 channels), and USB OTG FS with BCD support.

Board-level features include on-board ST-LINK/V2-1 debugger, external SMPS control interface, microSD card slot, audio codec (CS43L22), color LCD with touchscreen, MEMS sensors (accelerometer, gyroscope, magnetometer, humidity/temperature), and multiple expansion connectors (Arduino Uno V3, STMod+, Pmod) for modular hardware extension.

FAQ

What firmware and software tools are supported for STM32L476G-EVAL?

The board is fully supported by ST's STM32Cube ecosystem: STM32CubeMX for initialization code generation, STM32CubeL4 firmware package with HAL/LL drivers, and STM32CubeProgrammer for flashing and debugging. It integrates with Keil MDK, IAR EWARM, and GCC-based toolchains. Example projects include LCD demos, USB CDC/VCP, touch sensing, and sensor fusion using the on-board LSM6DSL and HTS221.

Does STM32L476G-EVAL support external SMPS operation out of the box?

Yes - the board includes dedicated circuitry to control and monitor an external switching regulator (e.g., ST1PS01 or similar), enabling the MCU's SMPS mode for optimal efficiency. Jumper JP1 selects between internal LDO and external SMPS power, and the board provides test points for VDD12 monitoring and enable signaling per the STM32L476xx datasheet Section 3.9.3.

Can the on-board LCD be used without external components?

Yes - the STM32L476G-EVAL integrates a 320×240 RGB TFT LCD with resistive touchscreen and backlight driver. The MCU's built-in LCD controller (supporting 4×44 segments or 8×40) drives it directly via parallel interface; no external display controller or voltage booster is required. Firmware examples in STM32CubeL4 demonstrate initialization, graphics rendering, and touch calibration.

Is ST-LINK/V2-1 on STM32L476G-EVAL field-upgradable?

Yes - the on-board ST-LINK/V2-1 debugger supports firmware updates via STM32CubeProgrammer or ST's dedicated ST-LINK Upgrade tool. This allows access to new debug features, improved USB enumeration stability, and enhanced SWD/JTAG reliability - critical for long-term development continuity and compliance with evolving host OS requirements.
