While my Dropbox bandwidth lasts, here's a huge (636 MB!) Photoshop file with the two layers of the Smart Response XE PCB aligned for tracing: https://www.dropbox.com/s/pqukn561evlj38x/smart%20response%20xe%20pcb.psd?dl=0
I want to discover everything there is to discover about this device and then use that knowledge to make something amazing with it. I'm starting with the hardware, so the first step is to trace the PCB design and obtain a schematic that can be used as a starting point for exploring what can be done with software running on the device. Towards that end I sacrificed one of my devices, cleaned off both sides of the PCB, and took a very high resolution scan of each side with a flatbed scanner.
Next up is carefully tracing out a schematic using the scan.
