6 Axis IMU

Well, its been a couple weeks since I last updated here. I've been pretty busy, working on a number of pieces of electronics for BrainBot* and MicroRaptor. The biggest achievement came today, when I got my 6-axis IMU bus sensor working. In my last post two weeks ago, I had the prototype board working, but since then I have had a proper PCB printed, mounted a bunch of very tiny surface mount parts, and got it all working.

This is a very small board. It measures 1.15" x 0.75" (about 29mm x 19mm). It has a 16 MHz ATmega168 onboard (the small square chip in the middle), two voltage regulators (3.3 volts and 5 volts), a bunch of capacitors and resistors, a couple LEDs, and a Bioloid bus plug. It also has a couple sockets where a Sparkfun 5-axis IMU board and a Sparkfun 1-axis gyro board can plug in.

You can see some more pictures of the IMU board here.

*The BrainBot project is directed and funded by the Brain Engineering Lab and Neukom Institute
