These are the unique features of PebblePower1:

• PebblePower1 should be as small and efficient as possible
• Its intended to be used to monitor and control a single device or light. The user provides power to the PebblePower unit and connects the output side to the device they want to manage.
• PebblePower1 will often be installed in hard to reach places and therefore doesn’t have a built in fuse. It relies on the circuit fuse or a seperate fuse can be installed by the user.
• PebblePower1 will have a 10A opto-coupled relay where common is the supply voltage to the external device and monitored with the INA226 or INA3221 and both NC and NO will available to the user. This means that the target device can default to On or Off and the power consumption will be measured.

PebblePower1 Example Layout

It should be noted that this is an example only. We would prefer that the design take an innovative approach and help to create a unique layout.
