On-board STLINK-V3E debugger/programmer with USB re-enumeration capability: mass storage, Virtual COM port, and debug port Comprehensive free software libraries and examples available with the Product status link STM32CubeG4 MCU Package Support of a wide choice of Integrated Development Environments (IDEs) B-G474E-DPOW1 including IAR , Keil , and STM32CubeIDE Handled by STM32CubeMonitor-UCPD (STM32CubeMonUCPD) software tool Description The B-G474E-DPOW1 Discovery kit is a digital power solution and a complete demonstration and development platform for the STMicroelectronics STM32G474RET6 microcontroller. Leveraging the new HRTimer-oriented features, 96 Kbytes of embedded RAM, math accelerator functions and USB-PD 3.0 offered by STM32G474RET6, the B-G474E-DPOW1 Discovery kit, based on the USB 2.0 FS Type-C connector interface, helps the user to prototype applications with digital power such as a buck-boost converter, RGB power LED lighting or a class-D audio amplifier. The B-G474E-DPOW1 Discovery kit does not require any separate probe, as it integrates the STLINK-V3E debugger and programmer. The B-G474E-DPOW1 Discovery kit comes with the comprehensive software HAL library together with various packaged software examples.

For a detailed description, refer to its user manual on the product web page. Additional information is available from the datasheet and reference manual of the target STM32. Table 1. List of available products Order code Board reference User manual Target STM32 B-G474E-DPOW1 MB1428 UM2577 STM32G474RET6U 1.1 Product marking Evaluation tools marked as ES or E are not yet qualified and therefore not ready to be used as reference design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will be liable for any customer usage of these engineering sample tools as reference designs or in production. E or ES marking examples of location: On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the STM32 datasheet Package information paragraph at the www.st.com website). Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board. This board features a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a marking option at the end of the standard part number and is not available for sales. In order to use the same commercial stack in his application, a developer may need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties. DB3835 - Rev 2 page 2/6
