Lora location transmittor with TinyGPS and rfm95 for Kaasfabriek project

  adjustment for fablab Kaasfabriek Junior IoT Baloon Challenge february 2017
             met leerling teams bij fablab de Kaasfabriek in Alkmaar
                     deze software op het internet is natuurlijk geheim...
                                  ...anders kunnen ze makkelijk afkijken!

Important

how to build your first node, practical soldering tips in nice pictures, https://www.thethingsnetwork.org/labs/story/build-the-cheapest-possible-node-yourself --> you will need to use our pin mapping instead

Pin mapping

    Suggested pin mapping:
    this new mapping puts the boards next to each other as shown in schema below,
          can be folded into compact stack or embedded in a business card size
