  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.

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

ISP header for bootloader?

yes

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...

The 2nd link has built in google translate (click the UK flag)

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
Released under CC SA-BY.

I will keep you posted.

Looks nice.

please use thermal pads on the ground plane

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

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