Thanks!

Hello, thanks for the reply, here are the changes made, please let me know if you see anything else that would be wrong, I added an option for 4 pin motors to be attached in the future.A couple comments from looking at the schematic.
You need a 100nF cap between Vcc and ground for the CH340.
The LM317 can't/won't regulate the 5 volt Vusb to 5 volts. It must have some overhead to work. This regulator shouldn't be needed.
