Overview

Lithium polymer battery unit. Charges and maintains battery from USB 5V, output 5V over USB, allows data to pass through.

Goals

  • No need to remove for basic operations
    • Charge through panel mounted USB port
    • Upload Arduino skectches through USB port
    • On off switch

Tentative BOM

  • LiPo Charger "Battery Babysitter" Sparkfun
  • Female Headers
  • Male Jumper Wires

Case

3D printed to mount and encase circuit boards in a end-user-friendly manner.
