    Documentation Center NOTE By default, IO4 is used as the Digital Output (DO) pin. DO pin can be changed by reworking some resistors on the PCB module. There are reserved options to change the GPIO to control DO. 3V3_S voltage output from the WisBlock Base that powers the RAK13007 module can be controlled by the WisBlock Core via WB_IO2 (WisBlock IO2 pin).
