We currently require detailed pin mapping documentation for the Apalis iMX8QM SOM and Ixora V1.3A carrier board. We have searched through the online datasheets but have not been able to locate a comprehensive pin mapping reference. Can you provide the Carrier board extension connector pin out?

Hello! Thank you for reaching out with your question regarding the pin mapping for the Apalis iMX8QM SOM and the Ixora V1.3A carrier board.
The Ixora carrier board uses an MXM3 (321-pin) socket to connect with Apalis modules. While specific documentation for Ixora V1.3A may not be readily available online, the pin mapping for this connector is largely consistent with previous versions, such as Ixora V1.2A.
To obtain detailed pin-out information, you must reference both:
- The Apalis iMX8QM module datasheet, which provides the SoM-side pin assignments.
- The Ixora carrier board datasheet for the corresponding carrier-side mappings.
For the extension connector (MXM3 socket) on the Ixora carrier board, please refer to the “Carrier Board Connector Pinout” section within both resources. You can find these documents and further details here:
Typically, these documents list each MXM3 pin number along with their signals. For complete and accurate pin mapping, always cross-reference both the carrier board schematic and the module datasheet, as signal availability may depend on the selected Apalis module.
If you need a general overview or an example table of how pins are mapped (e.g., UART, SPI, I2C, GPIOs), please let me know—I’m happy to provide more details based on supported board versions.
Best regards,
Toradex AI Assistant.
You can check this information right in the carrier board datasheet.
- The “Pin” column refers to the extension connector in the carrier board
- The “MXM3 pin” column refers to the SOM pin pad
- And the “Signal Name” is the associate signal to each SOM pin
Also, in the carrier board resources page, you can find the complete Altium Project, so you can always refer to the schematics.
Are you looking for a specific interface or a specific connector?
Hi Allan,
Thank you for your fast response, but we already know this. We need this list.
GPIO1 → MXM3 Pin#1 → iMX8QM BGA ball Pin#?
GPIO2-> MXM3 Pin#3 → iMX8QM BGA ball Pin#?
GPIO3-> MXM3 Pin#5 → iMX8QM BGA ball Pin#?
GPIO4-> MXM3 Pin#7 → iMX8QM BGA ball Pin#?
GPIO5-> MXM3 Pin#11 → iMX8QM BGA ball Pin#?
GPIO6-> MXM3 Pin#13 → iMX8QM BGA ball Pin#?
GPIO7-> MXM3 Pin#15 → iMX8QM BGA ball Pin#?
GPIO8-> MXM3 Pin#17 → iMX8QM BGA ball Pin#?
Thanks
Darshan
You can find the other half of the table in the SoM datasheet.
Check section “4.4 SoC Functions List”.
We can’t really have this in a unified table because
Each carrier board can support many SoMs
And each SoM can be supported on many carrier boards
Thank you Allan. Solved our query.
