This is a enclosure for my LoRa Arduino Pro mini GPS. On the bottom of the box I placed a 60x40x5 mm 1200mAh lipo battery. The switch is glued in place. Up the battery there is the midpart with the Arduino Pro Mini and the Ublox Neo 6 GPS module. The LoRa tranceiver is mounted at the backside of the Arduino Pro mini. I use a simple wire as a antenne and that works very well!
