Do you a supply a board or wire which these LEDs can be connected into? I am looking at using a 100 of these in 10 x 10 rows and the either have them plugged in to mains (with a resistor, if you can supply) .

You could use this power supply http://www.kitronik.co.uk/products/batteries-holders-chargers-usb-power/power-supplies- without a resistor it should be able to power 100 of the colour changing LEDs. If it struggles when a lot of the LEDs change to the more power hungry colours you may wish to use 2 power supplies with 50 LEDs on each. As for a board to do this, you could try these http://www.kitronik.co.uk/products/pcb-equipment/pcbs/strip-board-pack-of-5-100x160mm/ . One last thing, the colour changing LEDs don’t stay in synch for very long, they all have slightly different timings so after a few cycles they are all showing different colours.If you want control over the colours you would need to use http://www.kitronik.co.uk/products/components/leds/leds/colour-changing-and-rgb-leds/rg or the common anode version and some circuitry to control the timing of the colours.

If you mean these colour changing LEDs then yes http://www.kitronik.co.uk/products/components/leds/leds/colour-changing-and-rgb-leds/5vYou can connect them directly to the USB power supply without the need for a current limiting resistor.
