Today I went sorting through some USB cables, but before I could test anything, I had to solder the third and last of the boards that I had ordered years ago. The micro-B USB socket held for 15 cables before I had to add glue because it got loose [log for board 2]. So I decided to update some parts on the PCB and shift things around. 

• USB-A + micro/mini Sockets are turned 90 degrees, so you can test shorter cables
• additional USB-B connector so you can test A-B cables
• button is now a 6mm x 6mm sized one
• LEDs all point in the same direction and are marked, good for soldering
• Attiny13 was chosen as the firmware size is sub 1kB [[1kB challenge contest]]
• swapped to SMD coin cell holder
• changed micro-B footprint for something with 4 prongs 

Check out this old space ship of a schematic:

And here is the (hopefully improved) new schematics, I think it's more readible, but not everyone is a fan of too many labels. 

There's still one pin left on the Attiny, anyone any ideas for it?
