STM32H743ZIT6 embedded motherboard development (laser scalpel motherboard)

Strategy:

1. The power section uses a wide range of GND grounding, isolating the signal layer from the power layer to avoid signal interference;

2. The IXTH24N50L chip group is designed independently, with added heat sinks to form isolated power.
