The above image shows a light strip using the LPD06803s chip which controls 3 rgb leds.

I want to change the spacing of the leds so I was going to make a new circuit board but Im finding it hard to trace the circuit, Ive searched the internet but I cant find the circuit diagram, can anyone help?

thanks

Gary

That was a rough one See https://forums.adafruit.com/viewtopic.php?f=8&t=15768 and use translate.goggle.com on the Chinese datssheet nentioned in the forum.

Hi thanks for the datasheet, google is having problems translating, I only want a schematic of the circuit so I can reproduce it, surely there is a schematic somewhere? I will keep looking

Thank you for the chinese link, I could work it out from that, but I was hoping for a schematic to save me from having to design it
