I'm trying to make a PCB to coming the 4 breakout boards i have, the Leonardo tiny, mpu6050, bmp280, a 7.2v to 5.0v and a 7.2v to 3,3vregulator. and to connect two servos to the board with header pins. as well as having 2 header pins for battery input.
its the first time i have tried to develop a project like this, was unsure on many of the connections. i found multiple schematics contradicting each other. the main concerns i have is with the USB port and the 16MHz crystal. as well as general uncertainty for the other connections through out the whole schematic. I'm also uncertain on the connections for the two voltage regulators.
i have all the code and circuit running perfectly for the breakout boards on my glider. just trying the make the project neater and smaller to fit into a smaller airframe.
here's the schematic i have made
and the schematics i have based it off
