Arrived quickly to UK, the ones I have tested work well, the colour change will go out of sync quite quickly if you run several of them at the same time, but that was what I’d hoped for so can’t see any reason not to give them top marks. Would have been good to have a data sheet available, testing them here they seem to regulate current without an external resistor (within a ‘sensible’ voltage range) which would make sense, given the range of current required in normal use but would have been nice to see that in writing.

Arrived quickly and in good condition to UK. Tested on a cheap uncalibrated multimeter and got readings around 4400uf, but that’s fine for my purposes, and as I say, is probably more to do with the test equipment than the caps.

Spot on, it’s a small tin but I’ve been using this for a few months and it really does work, use it after you’ve finished soldering and leave it on the tip as it cools and you’ll have a shiny iron ready and waiting for next time.

Arrived quickly to UK and in good condition, they’re as per the description. I haven’t tested them yet but certainly seem to be good quality for the price and I expect them to be fit for purpose.

They arrived in good condition, I’ve used some in a circuit and they work great, bright with good colours.

D: Are the connection pins like: R,G,B,+

Domandata da Max Ietswaard il 2018-05-27 04:31:18

Dave These are common cathode leds, so the longest pin is the ground/0v connection, you need to apply a positive voltage to the other pins to light them. The pins are more like R,G,B, - really.
