So I a looking at the TM1809 strip that I got from diyledexpress and I have a few questions for folks who have already used it. While it appears to be cuttable every 10cm, the various sections are different. Starting at the input side and counting down the strip, it is obvious that the 1st and the 5th led/IC cluster have an additional 330 Ohm resistor that the 2nd,3rd and 4th clusters do not. It also appears that the strip has solder joints after every 5th segment where they join the pcbs together.
1) Is this really cuttable and usable every 10cm or 50cm?
2) Do you have start off each lengths of lights with a cluster 1 and a end with a cluster 5?
3) What role do the two 330 ohm resistors play on the design?
4) What is the solution if you want to use them in length other them multiples of 0.5M?
