RGB Led with 6 leads

I got this RGB led with 6 leads. The schematics that I found online did not match the LED that I got. So documenting here what I found out. There are 4 LEDs in this package, with 2 leds for blue, may be to brighten the blue colour since it has the least brightness among the three colours at a given voltage.

Here is a datasheet that is close in terms of everything except the leads.

USB-TTL adapter module

Got a new USB-TTL adapter for generic use. Based on SiLabs CP2102 chip and the module is very cheap - $3.29 shipped from ebay. Supports 3.3V and 5V and comes with lead cables for connections. Tried for my Baofeng radio and works just fine.
Tried on Windows XP (drivers from Silabs) and Ubuntu (default drivers).
