This module is a 5V module, and is rated for 5W max (5V/1A) but when we plugged them in they seemed to draw more like 1.5A so we suggest our 5V/2A power adapter for use.

This rotary encoder is the best of the best. It is a high quality 24-pulse encoder, with detents and a nice feel. It is panel mountable for placement in a box, or you can plug it into a breadboard (just cut/bend the two mechanical side tabs.) We also include a nice soft-touch knob with an arrow in it, fits perfectly and looks great.

These are standard '130 size' DC hobby motors. They come with a wider operating range than most toy motors: from 4.5 to 9VDC instead of 1.5-4.5V. This range makes them perfect for controlling with an Adafruit Motor Shield, or with an Arduino where you are more likely to have 5 or 9V available than a high current 3V setting.

Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable - so you only need 1 pin/wire to control as many LEDs as you like. They're easy to sew, and the chainable design means no crossed threads.

Measures 20 cm x 15 cm (7.9" x 5.9"), about 0.5mm thick. Its covered in what seems to be PVC, the panel is thus spill proof - but note that the connector is NOT waterproof, just a bit of heatshrink. This isn't something we would suggest leaving outdoors for extended periods.
