Hello,
after reading documentation and hardware user guides for MaaXBoard OSM93 it is still unclear to me how the pins from M.2 connector (J14) are mapped to the OSM93 module.
Are there anywhere more details than this diagram from the hardware user guide?
Especially information about the GPIOs is completely missing.
I also found out that the Block Diagram (Figure 7 in the Hardware User Guide) shows a differen SDIO interface than the one actually used.
Best regards,
Werner

I apologize for the delayed response to your query regarding the M.2 connector pinout.
Your observation is correct. The block diagram incorrectly shows SDIO_A, however SDIO_B was routed to this M.2 interface. The block diagram has been corrected and will be visible shortly in updated HW documentation.
The section of schematic showing SDIO pinout on this M.2 key-E connector (J14) is shown below:
