  Hello. Here is my attempt to create single-sided Arduino-Leonardo clone, with possibility of DIY-photoresist production. Designed in KiCAD. Dual LDOs (3.3V and 5V), additional connectors for RS232, I2C, SPI/ISP.
  Project repository: https://bitbucket.org/edartuz/ul_arduino_leonardo

C'mon, you can do better :)

Where did you get a schematic to copy, I thought they weren't released yet.

I don't think its far from official design, so final changes will be small

OK, no wonder I didn't see it, my Spanish is a little weak so I tend to skip that forum :)

I think you should move your traces further apart.  In most cases (ie the traces going to the digital IO pins), you have plenty of room...

Hi chaps,

since you've been following the Spanish thread I thought I would share with you the last events. The boards have arrived and are going to be beta tested by the vinciDuino team.

The boards look great. Currently waiting for components to arrive.

You can find all the information about the board: https://bitbucket.org/fmalpartida/vinciduino/wiki/Home

I will keep you posted.

??frank ?? Looks like its covered with ground plane on both sides.

Maybe could have used some more around the regulator, IC2.
