Hardware

Introduction Background Overview Subsystems Hardware Construction Software Demo Finances Conclusion

Rev A

  • Dev kit
  • Adaptable
  • Redundancies
  • Reused designs

from past groups

  • More of a backpack

than glove

Introduction Background Overview Subsystems Hardware Construction Software Demo Finances Conclusion

Rev B

  • Closer to production model
  • Significantly better design
  • BGAs & 0603s
  • Updated design for

vibration motors

  • Battery powered
  • Fully wireless
  • Smaller than a smartphone

(2.5” x 5.5”)
