The project I have been working on is for a USB stick capable of receiving wireless signals and inputting keyboard commands into the PC, with the ATMEGA32u4 being at the heart of it all. Through research, I have found many iterations of the 32u4 being used as a standalone microcontroller, each with their differences. Linked to this post is my interpretation of those.
My question is, Is my schematic sufficient to safely run the microcontroller though the USB power supply? Have I missed any vital components, or in fact can I get away with less?
I will be uploading the operating code via the 6-pin header, and sole operation will be run though the USB power supply.
