BNO055 schematic library for KiCAD unclear

[kuschel]

I've updated the schematics of the BNO055 according to the recommandations in datasheet REV1.8.

The question is: When the BNO055 is set to UART function (PS0=GND and PS1=VDDIO), then the COM1 is Rx.

Is this COM1 (Rx) an Input? And the COM0 (Tx) the output of the IC? Or vice versa?

Whould be nice, when the schematics (connection diagrams show the directions of the RX and TX lines as well as nRESET which looks like an Output, see Page 108 of REV 1.8 datasheet.

Also for XOUT32 is connected to the wire as "Optional OSC input", very strange.

Should the SWDIO and SWCLK be unconnected or pulled-up, when not used or pulled up/down when in use?

Hi kuschel,

Thank for your inquiry.

Reply: yes.

BNO055 has enabled the internal clock by default, so the external clock corresponding to XOUT32 is optional.

SWDIO and SWCLK can be disconnected when not in use.
