RAK13007 is a WisBlock Interface module that extends the WisBlock system to be used on isolated digital output
applications. There is one digital output that is isolated by an electromechanical relay. The RAK13007 digital
output is used to programmatically switch on/off devices operating at high voltage or high current applications.
For more information about RAK13007, refer to the Datasheet.

Assembling and Disassembling of WisBlock Modules
Assembling
The RAK13007 module can be mounted on the IO slot of the WisBlock Base board, as shown in Figure 4. Also,
always secure the connection of the WisBlock module by using compatible screws.

Disassembling
The procedure in disassembling any type of WisBlock modules is the same.
1. First, remove the screws.

Documentation Center
Figure 5: Removing screws from the WisBlock module
2. Once the screws are removed, check the silkscreen of the module to find the correct location where force can
be applied.
Figure 6: Detaching silkscreen on the WisBlock module
3. Apply force to the module at the position of the connector, as shown in Figure 7, to detach the module from the
base board.

📝 NOTE
If you will connect other modules to the remaining WisBlock Base slots, check on the WisBlock Pin
Mapper tool for possible conflicts.
After all this setup, you can now connect the battery (optional) and USB cable to start programming your WisBlock
Core.

Documentation Center
⚠ WARNING
Batteries can cause harm if not handled properly.
Only 3.7-4.2 V Rechargeable LiPo batteries are supported. It is highly recommended not to use other
types of batteries with the system unless you know what you are doing.
If a non-rechargeable battery is used, it has to be unplugged first before connecting the USB cable to
the USB port of the board to configure the device. Not doing so might damage the battery or cause a
fire.
Only 5 V solar panels are supported. Do not use 12 V solar panels. It will destroy the charging unit and
eventually other electronic parts.
Make sure the battery wires match the polarity on the WisBlock Base board. Not all batteries have the
same wiring.
Software Configuration and Example
In the example, you will be using the module. Before connecting high voltage modules to the RAK13007, make
sure to follow safety precautions.
For RAK13007, the accessible pin assignment is defined as follows in the Arduino IDE:
WB_IO4 for Relay Output pin

Arduino Setup
Figure 8 is an illustration on how to use the RAK13007 relay for switching applications. You can connect any
module or device to the RAK13007 as long as it operates on its recommended voltage rating.

If you have already installed the RAKwireless Arduino BSP , the WisBlock Core and example code should now
be available on the Arduino IDE.
1. You need to select first the WisBlock Core you have.

📝 NOTE
If you experience any error in compiling the example sketch, check the updated code for your WisBlock
Core Module that can be found on the RAK13007 WisBlock Example Code Repository . This sample
code in Github will work on all WisBlock Core.
3. Once the example code is open, you can now select the right serial port and upload the code, as shown in
Figure 12 and Figure 13.
📝 NOTE
If you're using the RAK11200 as your WisBlock Core, the RAK11200 requires the Boot0 pin to be
configured properly first before uploading. If not done properly, uploading the source code to RAK11200
will fail. Check the full details on the RAK11200 Quick Start Guide .

4. When you have successfully uploaded the example sketch, you will now see the RAK13007 Relay module
switches the LED on and off every 5 seconds. Also, notice that the built-in red led on the RAK13007 module
lights on when there is contact, or it is normally closed, and then lights off when it is normally open. You'll also
be able to hear clicking sounds from the RAK13007 module, which means that the relay is switching.

Specifications
Overview
The overview covers the RAK13007 block diagram and the mounting mechanics of the board into the WisBlock
Base board.
Mounting
The RAK13007 module can be mounted on the IO slot of the WisBlock Base board. Figure 2 shows the mounting
mechanism of the RAK13007 on a WisBlock Base module, such as a RAK5005-O.

Hardware
The hardware specification is categorized into four (4) parts. It discusses the pinouts and their corresponding
functions and diagrams of the module. It also covers the electrical and mechanical characteristics that include the
tabular data of the functionalities and standard values of the RAK13007 WisBlock Relay Module.
Pin Definition
The RAK13007 WisBlock module has a 40-pin WisConnector that is compatible to the WisBlock Base IO Slot. The
pin order of the connector and the pinout definition is shown in Figure 5.
Figure 5: RAK13007 Pinout Diagram

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). This makes the module ideal for low-power IoT
projects since the WisBlock Core can totally disconnect the power of the RAK13007 module.
