The NetCube Systems Nagami Keypad Carrier uses the Nagami SoM and contains a TCA8418 connected to a 4x4 matrix keypad. The I2C2 interface is connected to said TCA8418 and also a header for an PN532 NFC-Module. It also provides a pin-header for a bi-color status led. Ethernet with PoE support is available on a screwterminal after magnetics.
