poor quality.. two red and blue lights... tried with 3s, both red lights spoiled after a few minutes.. only two blue lights are working now..I really like this led Module.
It's really simple to solder and the LED's are so bright, that I can't watch them directly :-)
The LED's circuit board is on a very hard and durable aluminium plate, so you can hook them, directly under your quadcopter arms, using the motor screws.
The potentiometer on the control board, allows you to fine tune the frequency of the Led's blinking. (It's a multi-turn potentiometer)
The only thing I don't like is the fact that i did not buy another one for my hexacopter ;-)very goodddddddddddddddVery poor quality.
If you connect wrong cable, the plaque ruptures. No protection diodes.
A red LED has been broken when connected.It is a two color Red and blue, the leds are 3,3v.
one led red only was working 10 seg.
the red LED broken to connect.
The module is 50mmx50mm
