    I have the same problem with A5
    We have bought 60 pieces at very high price through our EMS supplier in China. (Suppose to be legit, we have done a few productions so far).

    A5 doesn't work at all and appears to consume a lot more power than A8 which works just fine.

    Has anyone know if A5 is an authentic part?

    I also bought some A5 chips in China and all don't work. The chips do not answer the I2C request at all. I do business with the same dealer for many years. I guess the chips are not fake, but there are some problems in Bosch manufacture and testing.

    Hi,

    Yes, we confirmed finally with Bosch DE, the BNO055 chips we bought was from Bosch, but they are Engineering version, not Mass production version, which means you can't use them according to the datasheet.

    And later we already ordered correct BNO055 for our mass production then.

    But now the BNO055 Chip is so expensive, we are trying to use BMI170 to be as an alternative.

    If you need service, eg, sourcing components, protpotype PCBAs or final product assembly, we can of course offer these service,

    We are in ShenZhen,China.

    And I'm from NOA Labs

    Hi all,

    If your stock is bought from an official distributor, please contact them first and we will support you if you have some issues.

    If your stocks are purchased from unofficial channel, please contact your supplier. We can't track these stocks and provide technical support.

    Thanks for your understanding.
