Pretty much anything.



  • Just adding to other requests PLEASE PLEASE adopt a consistent pinout so this and the other boards can be “stackable” with the Honeywell compass/magnetometer etc.<br />
    <br />
    Also to add to the request for a 9DOF with I2C directly accessible.<br />
    <br />
    Thanks<br />

  • I have rewritten the original SF9DOF_AHRS V1.1 code and re-included the features of V1.0 while still allowing it run on the Atmega168. The free running update rate with representative binary attitude output is ~160Hz. I did this as part of an evaluation for use in future implementations of UAVX.
    The code is at:
    Having an I2C connector would have been VERY useful if that can make its way into future versions of the board:).

  • Neat product.
    Perhaps add a 3.3V regulator footprint. I am using the board between a LOCOSYS GPS unit and a 5V PIC and currently have two diodes to get about 3.8V from the 5V line - not ideal.

No public wish lists :(
