# 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
