Matek Flight Controller H743 SLIM V4

What is new on the H743-slim-V4

• Increase the output current of BEC5V from 2A to 2.5A, and raise the filtered VBAT current from 1A to 2A.
• Add TVS protection on Input voltage
• Add protections on more MCU I/O.
• Replace DPS310 with DPS368(environmentally protected against water (IPx8), dust & humidity)
• Other functions, Pins/Pads layout are same as previous board version.
