This is a hobby project by Martin Harizanov. A small Arduiono with usb and radio module.
This is v3 of my “Funky” Arduino clone, specifically designed to be small, with on-board radio module and for low power applications.
Fritzing is a useful PCB design editor and on their site (http://fritzing.org) you can as well find a lot designs shared by others.
I haven’t yet tried the Fritzing fab, to turn you design into a real pcb, but will put it on my wish list.
