Power Options

The Smart Citizen Kit can be powered with a normal 5V 2A USB charger via micro USB port. Outdoor deployments, or more complex setups (like the Smart Citizen Station), require a more rugged power supply. More documentation available in the docs. Here are some options:

Smart Citizen Power Supply

A simple power supply to power the SCK with a 230AC input, with 5VDC 2A output.

The power supply can be one of two options:

It also comes with a 1.6A input fuse and two screw connectors. Check the datasheets for other available input convertions and limits.

The PCB has the footprint to fit inside a Bopla Polymas PK 102-211 IP65 Enclosure with two built-in cable glands.

The hardware design files can be downloaded as a zip file here.

Solar Panel

We recommend a Solar Panel from Voltaic Systems, either the 6W 6V option or the 5W 6V version.

We use an MPTT Sunflower Solar power manager 5V from DF Robot for managing the solar input with an additional 2Ah battery. It is fitted inside the enclosure with a small laser cut (or 3D printed if not available) flange. This is the BOM for this option.

Enclosure

A Bopla Polymas PK 102-211 enclosure is used for both options. The models can be found in the manufacturer's site in STP format. More references are available on our GitHub repository.

Extras

Some extras are included in this folder for cases in which power distribution + USB data is needed, or a tiny board to host a reset button:
