Wow, I must say that this is very cool indeed. Too bad it doesn't work directly with the SparkFun LCD backpack, but modification doesn't look too difficult. And thanks for keeping the price quite affordable
Well, it works directly, from the sound of it, it's only the last pin that you don't connect and then you connect three cables to the last 3 display connections and your pwm pins. Not exactly difficult...
It is also a good price as you said. I have no need for one but it's gone on my list nontherless cos I want one!
