  • 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 :(
