The B-G474E-DPOW1 Discovery Kit is a complete digital power development platform built around an STM32G4 MCU. It features an onboard buck-boost converter (with selectable internal or external input and resistive load bank) and a high-brightness RGB LED, allowing developers to evaluate DC-DC conversion and LED lighting control designs. A Class-D audio amplifier circuit is also included to demonstrate digital power in audio applications. The kit provides rich user interface and connectivity, including four user LEDs, a 4-direction joystick, a USB Type-C™ port supporting USB Power Delivery 3.0, a Micro-USB port (for ST-Link), and extension headers for additional peripherals.
