Quick Update: I looked at different ways of manufacturing the part I need in U.S. as well as in China. Like any other product you have to produce and order large quantities along with engineering specs, bill of material, provide them with SMD parts, pay for board, assembly and shipping. Even with large quantities in production, I can not beat the cost of combination of already made products. In conclusion unless some manufacturer comes up with the ready made product all in one very cheap, I opted to use two small devices instead. 1- 12V WS2811 SMD PCB (Boards used for RGB nodes) which includes Data in, Data out, RGB out. Max sinking capability of 20mA per channel. 2- 12V RGB SMD Amplifier. This product amplifies RGB (20mA) upto 4A per channel and feeds off 12V supply. Here is how it works: SPI signal arrives from TinyPixel or SPI SD-RAM card controller in the form of +V, Data, Ground. Also +12v and Ground from Supply feed into the WS-PCB. At the same time WS-PCB provides SPI data to the next RGB+ module. The RGB+ output of the WS-PCB simply connects to RGB input of Amplifier and output of Amplifier connects to 12V RGB Module up to 4A per channel (R,G,B). Amplifier also has a separate +12v and ground supply line that can be connected to WS-PCB and 12V supply line pair. I was able to find WS-PCB online from China at about $0.30 each and RGB Amplifier for about $1.10 each. Total cost of parts including free shipping $1.41. The rest is just simple wiring. WS-PCB board is 10mm x 20mm, and RGB Amp is 10mm x 25mm. Both can be wired to be inline for each RGB module.
