In sum, if sensor application is not needed, this expansion header can provide two full
BLSP7 and BLSP5 for UART/ SPI/ I2C/ UIM. Please refer to the schematic and consider
the power before connecting anything to this header.
Note that there is an unpopulated Gen-10 connector header (J2502) footprint at the bottom
of the carrier board. Install the Samtec (part number: QSH-030-01-L-D-A) connector here if
needed.

Figure 14 J2401 NFC expansion header
This digital IO expansion header J2401 is a 20 pin connector for attaching an optional NFC
board This header also allows user to connect to the free GPIOs and I2C lines when NFC is
not used; therefore, enabling other use cases. Please refer to Table below for detailed
information regarding the signals that are being brought out by this connector.
