The AllPixel provides 5V logic on the DATA and CLOCK pins, which is in the range of all the support chipsets. In general, 5V power is also required. There are some strips however that will use higher power voltages such as 12V and typically have clusters of 3 or more LEDs per "pixel". These will work fine, as long as they still use 5V logic.
Check out the bottom of the main page for the "Extras" section and check the pricing of the extras you want. Then in "Manage Your Pledge" there is a text box where you can enter a new pledge amount. Simply add the amount of your desired extras to your pledge amount and save. At the end of the campaign, we will send out a survey to everyone, asking what extras they chose.
