• Programming adapter

  Kirschner Christoph • 01/01/2018 at 21:23 • 0 comments

  This makes programming a lot easier!! :)

• Last PCB ~ you better be fast

  Kirschner Christoph • 12/15/2017 at 15:01 • 0 comments

  I sold all other pcbs of the cap. buttons and now one is still here :) 

  Any Fairphoners out there who want one :) 

  I also can solder everything up for you if you want that :) 

  Text me if there's interest !!! :) 

  Edit: sold !! 

• New PCB

  Kirschner Christoph • 12/10/2017 at 12:54 • 0 comments

  I designed and ordered a new PCB for the Fairphone 2. 

  It`s much like those prototyping-shields you have for your Arduino. And the purpose is to start tinkering and building things in combination with the PF2. This can not only extand your possiblities you have with your phone but also gives you the full control of the additional hardware you want.

  Feel free to ask whatever is on your mind :)
