Pin Definition​

The RAK15006 WisBlock 512kByte FRAM Module comprises a standard WisBlock connector. The WisBlock connector allows the RAK15006 module to be mounted to a WisBlock Base board. The pin order of the connector and the pinout definition are shown in Figure 3.

Figure 3737: RAK15006 WisBlock FRAM Module Pinout Diagram

The WisBlock Sensor connector is used to this module and the IO used for WP pin at Pin 12 will depend on where sensor slot the module is plugged in. The table shows the compatible pins used by different sensor slots:
