Workshopping £1.40 Arduino-Compatible (£3.05 including USB!)

Thanks, Florinc.

I missed out the ground wire to the reset button too :frowning:

I've attached a more accurate diagram to reflect your change and the ground wire, with extra information on the resistors, capacitors and resonator and a layout which still leaves room for female headers if people need them for any reason, although you can compress this layout to lose extra lines if necessary in various ways, depending on the physical size of things like the button.
