From the project
Custom 42x42mm 4-layer STM32F722 FPV flight controller for 5in and 7in cinematic and telemetry quads.
Vayu (वायु) is the Sanskrit word for wind.
This is a 42 × 42 mm, four-layer FPV flight controller built around the STM32F722 for 5-inch and 7-inch quads doing cinematic, telemetry, and general performance work. It is designed to sit in the same class as well-known F722 boards while adding a cleaner power layout, a proper barometer, and a 10 V rail sized for an HD VTX or analogue system.
