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.
