I am trying to find allan variance noise characteristics on gyros, but most datasheets don’t include it. Have you posted your measurements anywhere online? Also, which sensor models did you compare?

They are available at the page for the previous revision of this module. The only difference is that the headers are left unpopulated in the newer one.
Is there a difference between the RN-41 and RN-42 from a manufacturing standpoint? They share similar packaging and footprints, yet the prices for boards based on the RN-42 have a much smaller price difference over the bare device than similar examples for the RN-41.
Thanks for explaining this, Robert. While I do not know how SparkFun incorporates development costs in the final selling price of a product, this pricing still seems inconsistent.
Is there a good reason why a PCB and two capacitors cost $35 over the price of the module alone? I can understand some markup, but this seems unusually high.
No public wish lists :(
