First initial testing, after fixing some minor errors i made in the layout (Swapped RX/TX, not first time) and swapped D & S on the Fets. Grrr…

I’m in the process of building a 5x5x5 LED Cube like many others. The firmware is designed by [SiGNOUT] and [knielsen] from the local Hackerspace.

Their Cubes use a Seperate Arduino, and TLC5940 LED-drivers in TSOP housing. I would like to push the limits on my version of it, so i ordered the TLC5940 and Atmega328P in the smallest possible cases available. I would like to try BGA some day, but BGA requires more than dual layer PCB, so that’s impossible without professional PCB’s. The Atmel is 4mm² and the TLC5940 is 5mm².

The board is 2-layer and has holes through plated chemically. It is made on our Protomat & Minicontac II.

Here’s some pictures of the milled PCB:

There’s pictures of another PCB in the folder, an Infrared LED exposure device for Playing with a Laser printer.
