# ATTMapper Case

The case uses 3 parts:

- The Inner Frame, holding the ATTNode, GPS and OLED Module
- Front Cover
- Back Cover

See pics/assembly* for some hints on how to assemble the frame part. This part is identical for both case variants.

Front and Back Cover exist in two variants:

- attmapper_battery_* for use with a small LiPo Battery (I use a 550mAH 20x35x8mm Cell)
- attmapper_nobat_* for connecting a cable and mounting it in a car or similar with external power
