In addition to the PNL10, what else do I need to provide to complete a speed display product?

To complete a working sign you need to provide just a suitable enclosure and power source (AC to DC converter for AC powered signs or battery and charger for battery-powered signs.In fact, we will even suggest to you a suitable AC to DC converter (available for about $10) as well an advanced LiFePO4 battery, AC charger or maximum power point technology (MPPT) ultra-low standby power solar charger to use with your final product. To derive the maximum benefit from our ultra-low power usage PNL10, it is important for it to be matched up with similarly advanced components to complete the sign.
