Finally worked up the courage to build this one :) after hours of assembling, testing, hacking the code, debugging, probing etc.. I finally managed to run the first script :)

This one has everything OpenMV1 has plus an SDRAM, 2 IR LEDS, 2 servo headers, a power management chip, and 20 I/Os... Here's a closer look at the sensor block:

I ordered a few sensor chips weeks ago, but still haven't received them yet, I couldn't wait any longer, so I took one out from a sensor/lens package,  it looks like I tore off some pads while desoldering it, now I'm forced to wait for the sensors before I can do further testing :(
