Hi,
As I saw many design on the forum and on the Internet more generally, I post mine here in order to get some feedback and help from others.
My design was mainly inspired by the MeshDrone F4 design.
The Goal of the design is to understand the hardware setup of a F722 flight controller with commun features :
Low profil design.
SD Card slot for BlackBox data recording
Low noise MPU6000 SPI Gyro.
USB detection
low noise regulators for MCU and IMU power systems.
High Speed SPI 8kHz Gyro
Dedicated Boot button for easy firmware flashing.
VIN + VBAT merged - will provide voltage input and Telemetry/OSD voltage data.
Filtered voltage output - output 5v 1A (and 3.3v where applicable) to power peripherals such as GPS, RX, BLACKBOX, OSD. 5v/3.3v RX selectable.
Betaflight support
BLHeli passthrough flashing supported by hardware.
