The EFW mini is the smallest and most lightweight 1.25″ Electronic Filter Wheel in the world! Handles 5x1,25" or 31mm (unmounted) filters. Weights 300g only. Thickness is 20 mm.

Only one USB Cable is enough to power up the EFW, the max power consumption is around 120mA@5V, so you can powered it through the USB port. 

The Electronic Filter wheel can be rotated in both counter clockwise or clockwise direction for filter selection.
