Assembly details[edit]

  • Antenna must be connected before powering up device (or risk burning out radio)
  • Battery connector may not be correct polarity, check before connecting
  • Antenna connector has a limited number of insertions (10-50) before it wears out!!

Software details[edit]

  • firmware

Case options[edit]

Currently working on a 3d printed OpenSCAD model

Case features:

  • (mostly?) unobstructed USB C port
  • exposed screen (>2mm bezel step, may taper later)
  • holes for buttons (with possible external button extensions)
  • Antenna port on opposite end from usb port, oriented so it points up when screen is landscape
  • battery enclosure
    • possible hinged back plate to minimize battery wire yanking on open
    • possible tpu shock mounting for battery

Future features:

  • rotary encoder mount location, maybe under antenna
  • possible on/off switch
  • mounts for internal accessories
    • piezeo speaker?
    • cell phone buzzer motor
    • barometer
    • neopixel strip

Accessory purchasing[edit]

These parts lists are preliminary and overlap. Not all parts are required. Some parts may require firmware changes.
