WS2812B RGB LED comes in two flavors - single SMT chip or a SMT chip mounted on carrier module.
Both types of hardware can be mounted "side by side" - cascaded with input on one side and output on the other , thus soldered / connected / chained together as one unit.
Which hardware would be mechanically preferable if I need to build non flexible , rigid , strip of four of these?
I use the chip version mounted on strip PCBs.
This are a bit hard to hand solder, make sure the pads lean towards large.
.
That's where that reflow oven comes in handy ...
Ok,chip it is.
This is just for "proof of concept" - "dead bug" style.
I suppose I could use chewing gum to make them stay put before I attempt to solder them.
In my limited experience with these SMT buggers , they get stuck to the iron and that is the main problem.
Thanks
I use a very small amount of gel glue to hold them into place, let dry first.
