Hi, you can pull out the SPI/UART/I2C signals from the debug board if
your sensor IC is SPI or UART or I2C interface.
another alternative is to find the testpoints according to this pic
and solder out the connections from the test points to your IC.
the test points are labeled accordingly and they surround the FPC connector.
