new LEDs are working & new control board layout

A project log for 384:LED

Mini (1.44'' x 0.94'' or 24mm x 37mm) 8X16 RGB LED Array. 128 RGB LEDs with three LED chip each gives 384.

The new LEDs are the right ones. Now at least the LED PCB do work. Here is a picture of the soldered LED PCB:

I also redesigned the control PCB: Now the bigger SOT23-6 Transistors do fit and it is inside of OSH-Park's Manufacturing specifications. The new board for the contol PCB are already orderd. So I hope I will have a first working prototype soon.

PCB is looking good. I am sure this display will be fun to play with.

that is such a beautiful display! is the pin spacing 1.27mm? I think I need a coin or fruit for reference.

Thanks!
Yes the pin spacing is 1.27mm/50mil. As reference there is also the 1mm grid on the paper in the background. But you are right a coin (or banana) would me more obvious.
