Following are the requirements for the ammeter board that will be included in the second revision of the battery harness.

Requirements:

  • handle DC current of up to 2 amps from a single cell lithium battery
  • precision <= 1 mA
  • be able to measure voltage as well as instantaneous current draw
  • high sample rate (1 kHz)
  • ability to programatically disconnect and reconnect the battery
  • push capability, where we can ask to start receiving data at a given rate over the usb link
