- Integrated X- and Y-axis gyro on a single chip
InvenSense's product page (and the original article) state the IDG 600 is a dual-axis gyro which would indicate each chip is approx $2. This leaves out the 3rd axis which would mean the WM+ would need 2 of these chips raising the cost to $4 in InvenSense's chips. So it may be possible to have a MSRP of $15 although I'm still leaning towards $20.
