The Energy Probe is designed to be a low impact, inexpensive solution to give you quick feedback on the impact of your code on the system energy footprint. It is not intended to be a high-precision data acquisition instrument for power benchmarking.
The Energy Probe has three power connectors, each of which is designed to connect to a 2-pin header for measuring the power. This allows the energy probe to provide three independent power, current, or voltage measurements.

In addition to the three power connectors, the Energy Probe has a single pin GND connector that must be connected to ground on your target board. It provides a ground connection for the Energy Probe.
Each of the three power connectors measures:
