DISCO-L496AG

STM32L496 Discovery kit, cellular ready, LCD, USB, Audio, QSPI, Camera interface

Overview¶

The 32L496GDISCOVERY Discovery board is a complete demonstration and development platform for STMicroelectronics ARM® Cortex®-M4 core-based STM32L496AG microcontroller. Thanks to the innovative ultra-low-power oriented features, extended RAM and graphics performance (Chrom-ART Accelerator™) offered by the STM32L496AG, the 32L496GDISCOVERY board is designed to enable easy prototyping for many applications, including audio and graphics, with state-of-the-art energy efficiency. For even more user-friendliness, the on-board ST-LINK/V2-1 debugger provides out-of-the-box loading and debugging capabilities.

• Discovery board + Quectel BG96 LTE Cat M1/Cat NB1/EGPRS expansion pack

Known limitations¶

The following section describes known limitations of the platform. Note that general issues are tracked into the mbed repository available on GitHub.

• The volume name when the board is connected is displayed DIS_L496ZG while it should be DIS_L496AG (to be aligned with the STM32L496AG MCU on the board). This is only cosmetic and it has no effect with STLink communication (drag&drop, debug and VCP).

If you want to change the volume name, you can run the command:
ST-LinkUpgrade.exe -force_prog -msvcp -volume DIS_L496AG (you have to install first the STLink Utility software).
