Specifications
Overview
Mounting
The RAK19002 module can be mounted on the slots A, B, C or D of the WisBase board. Figure 2 shows the mounting mechanism of the RAK19002 on a WisBase module, such as the RAK5005-O.

Pin Definition
The RAK19002 WisBlock boost module comprises a standard WisSensor connector. The WisSensor connector allows the RAK19002 module to be mounted on a WisBlock baseboard, such as RAK5005-O. The pin order of the connector and the pinout definition is shown in Figure 3.

Figure 4235: RAK19002 power pinsThe following table shows default IO used for different slots:
| SLOT A | SLOT B | SLOT C | SLOT D |
|---|---|---|---|
| IO1 | IO2 | IO3 | IO5 |
- Only one IO (as a IC enable pin), VDD, and GND are connected to this module.
- Connect R1 or R3 resistor to select the IO pin. Check the schematic diagram in Figure 7.
- The slot B is not recommended because the IO2 pin is used to control power supply 3V3_S on WisBase RAK5005-O.
- The maximum recommended current is 50 mA ( VIN=3.3 V ).
