Hi Nikolaus, Very good stuff, an open phone with OMAP3530-Power, my dream...
I am a little off topic here, but I take the chance to ask eitherway. I am thinking about a little simpler NaviBoard. The actual Naviboard has 2x2 ADC with I2C and one 2axis Gyro(analogue) and one 1-axis gyro(analogue). A few weeks ago Sparkfun announced a new 3-axis gyro with I2C (IDG3200), which would make the Naviboard much simpler, I guess, and give the chance to add the pressure sensor (BMP085) to the PCB. I have one of these gyro on a breakoutboard in my hands, the chip is really tiny with a tiny tiny footprint. I think I will be able to solder the pressure sensor with a reflow oven in future (when my reflow oven is finished), but this gyro and the honeywell mangneto sensor. How do I solder them? How do I apply the solder paste to such a fine grid with no special epipment? You said, you also have at least one chip with BGA (0.5 pitch I guess) on your board, how did you manage to solder this during prototyping? Any tipps? Anyone? Thank you all in advance, Joerg On Wed, 2010-06-16 at 17:56 +0200, Dr. H.
