Arduino Micro project with Bluetooth low energy I created my project prototype with Arduino Micro and Adafruit Bluetooth low energy device.

Now I need to develop the prototype to production (like a small USB device). I just need Rx, Tx, 3V pin from Arduino Micro.

I started design with ATmega32U4, USB and BLE by using Fritzing IDE. I am confused with Arduino Micro parts like reset, bootloader and other pins. Is there any problem if I leave the unwanted pins from Arduino unconnected, for my project? Will it work correctly like a Arduino micro?

This is my first PCB design. Please help me to design a final PCB with the unwanted pins left unconnected.
I have started to look at the Arduino Uno schematics, which are free on the website. To make an Arduino is very simple, just need the chip, crystal, a few capacitors and that's it.

Try to copy the same schematics then add the Bluetooth to the RX and TX pins, but be careful about the 3.3V as you don't want to fry your Bluetooth module :)
