THESE THINGS ARE GREAT!! I love them. Bought one sheet to experiment with and I'm already making little lighting projects all over the house. This a board of 100 individual (not connected) pcs that you snap apart for use. They are not connected to eachother on the board. They connect in series - 3 wires going in, 3 wires going out : 5V, Data, GND. The wiring direction is printed on the back, just follow the data direction and it's super easy. Currently I've only found one Arduino library that works proper with the 4 colors (RGBW) and allows bit-banging and that is FAB_LED.h. Adafruit and FAST_LED can be tweaked to work. It took me a few days to figure out how to code them but once you figure it out (Google is your friend) they're real easy to use. Datasheet and documentation are not hard to find. Already ordered again..

Il est arrivé à lui rapidement et je suis heureux, un détail, j'espérais que les carrés arriveraient complets, mais l'un d'eux a un led séparé, et l'autre est divisé en deux. Cela ne semble pas affecter le fonctionnement, en fait, il semble être conçu pour les renverser, mais je voulais qu'ils soient tous ensemble. Quoi qu'il en soit, maintenant je vais devoir penser à les utiliser séparément.

Le llegó rápido y estoy conforme, un detalle, esperaba que llegaran completos los cuadritos, pero uno de ellos trae un led separado, y el otro está partido por la mitad. No parece afectar el funcionamiento, de hecho parece estar diseñados para desprenderlos, pero yo los quería todos juntos. Como sea, ahora tendré que pensar en usarlos separados.
