    BNO055 voltage levels for non-UART/I2C signals

    BNO055 voltage levels for non-UART/I2C signals

    Hi there,

    I have a question about specs for the BNO055 sensor. Table 0-1 of the datasheet specifies Voh, Vol, Vih, Vil, but only for UART & I2C. I found nothing in the datasheet that specifies levels for pins like nRESET, INT, nBOOT_LOAD_PIN, BL_IND, etc.  But maybe I missed something.

    Table 5-1 basically says that the UART/I2C signals (COM0-COM1) are of the same type as nBOOT_LOAD_PIN, BL_IND, etc (e.g. "Digital out", "Digital in", "Digital I/O").  So maybe this hints that the I/O voltage levels are the same.  But I'd rather see it stated in black & white, if possible.  Especially since pins like nRESET are listed as being of type "--".  

    Does anyone know where I can find this information?  I tried a live chat with Bosch but that wasn't helpful, no offense intended.

    Thanks!

    Steve

    Hi SVK,

    Normally, they had same characteristic for non-supply pins as they had same VDDIO supply.

    Thank you for the information - I appreciate it.  I'm assuming that by "non-supply" pins you mean the unspec'd pins I was referring to like nRESET, BL_IND, etc. (i.e. the non-UART/I2C pins).  Is that correct?

    Thanks,

    Steve
