The MR-CANHUBK3-ADAP is an optional adapter board for the MR-CANHUBK344 that includes a SD card interface, sensors and Dronecode connectors to ease the use of PX4 on the S32K344.
See for more complete usage of this board in a robotic system
It includes the following:
ICM42688P IMU
BMM150 Magnetometer
SD Card slot
Dronecode 10-pin GPS connector
JST-GH 6 Pin RC connector
JST-SH 4 Pin I2C connector
The current main branch of PX4 auto-detects this board and changes the settings for the sensors and output accordingly.
To check whether board detection was successful you should see the following output on boot.

HW arch: NXP_MR_CANHUBK3
HW type: MR-CANHUBK3-ADAP
The UART mapping for MR-CANHUBK3-ADAP is as follows. GPS - GPS_1_CONFIG - 202 RC input - RC_PORT_CONFIG - 104
MR-CANHUBK3-ADAP also provides VBAT ADC circuit. The voltage divider is set by the BAT1_V_DIV PX4 parameter. It's recommended to re-calibrate this divider for accurate voltage measurements.
The SD card needs to be wired up using a 7-pin JST-GH connector, where the MR-CANHUBK3-ADAP SPI connector has to be connected to the MR-CANHUBK344 P1B SPI connector. Note straight cable connection i.e. pin 1 to pin 1
