FreeIMU is alive!

Yeah! I soldered everything and all went smooth.. only a little bug.. the connectors have a 0.032″ drill hole while it should be 0.04″.. so, regular squared pins array wont fit inside. You can use rounded pins, female thin pins (as the one shown in the video below) or wires directly.

But everything works great. Communication on I2C running at 400Khz directly from Arduino through the on board I2C level converter.. works great!

Next days more tests, I’m expecially interested in having a look at how the I2C signals looks on a scope with or without the I2C level converter.. I’ll also try to simulate some noise and using long wires to check what happens..

Here is a short video on the progresses done these days.
