12.1 Energy Probe overview

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:

Caution

The Energy Probe has flying leads and must be carefully connected to your target. Do not plug the green ground wire into anything but the target ground. This includes I/O pins and power pins. Doing so could cause damage to your Energy Probe or the power supply of your target.
