IMPORTANT NOTE: These are NOT drop-in replacements for standard Disco or Daylight on a sticks. These sticks use 4-pin JST-PH with Din and Dout pins on each side, while Disco/Daylight use 3-pin JST-XH. You will need to re-pin your wires. The bolt hole placement is also slightly off because the LED density is higher.
These sticks are much improved over Disco sticks and sooooo much brighter. I appreciate the switch to 4-pin connectors to allow chaining off either side.
And if you don't know what the little switch on one side does, this is from Provok3d:
> Onboard switchable data line resistor for best data clarity (only use one per continuous string of LEDS)
