Overview
To give you a better understanding of how the WisBlock Base works, the block diagram RAK19011 is provided in
this section.
Block Diagram
The block diagram shown in Figure 1 shows the internal architecture and external interfaces of the RAK19011
board.

The MCU in the WisBlock Core module offers the I2C, UART, and SPI data buses to the sensor and IO modules.
Through these buses, the MCU can control and retrieve data from the sensors. The RAK19011 WisBlock Dual IO
Base Board with Power Slot board connects all these modules.
Hardware Setup
RAK19011 WisBlock Dual IO Base Board with Power Slot
Installation Guide
RAK19011 WisBlock Dual IO Base Board with Power Slot is the main board that allows you to attach MCU, Power
modules, sensors, and IO modules through the standardized expansion connectors. These connectors provide a
data bus interconnection between the modules attached to the RAK19011 WisBlock Dual IO Base Board with
Power Slot.
This guide shows the details related to the installation of modules into the RAK19011 WisBlock Dual IO Base
Board with Power Slot.
Attaching a WisConnector
The WisConnector is the interface between the RAK19011 module and the WisBlock Core, Wisblock Power,
Sensor, and IO modules. Before connecting these modules, read the following instructions:
📝
NOTE:
This guide uses two arrows. Refer to Figure 2 for its representation.
Figure 2: Notation within the guide
1. Align the connectors. Keep the header parallel and place it lightly in the corresponding lap joint of the socket.
Documentation Center
Figure 3: Alignment of WisConnector
2. Fit the connector. Tilt one end of the connector (header) less than 20 degrees, while do not apply force during
this process, gently place the other end in parallel.
Figure 4: Fit the WisConnector’s header inside of the socket
3. After the above alignment steps, the header and socket are matched but still not buckled.
Figure 5: WisConnector’s header matched inside of the socket
4. Apply forces evenly by pressing in parallel, then there will be a sound confirming the completion of the buckling.
Figure 6: Apply forces to buckle the heard to the socket
5. In the process of buckling and applying force, avoid the application of uneven force on both sides.
Documentation Center
Figure 7: Avoid applying uneven forces
6. When the buckling process is completed, check that the header and socket are kept in parallel.
Figure 8: Correct way to buckle the WisConnector’s header to the socket
7. After buckling, if the header and socket are not in a parallel state (not fully assembled in one place), press with
even force on both sides of the long side to complete the correct buckling.
Figure 9: WisConnector’s header is not parallel to the socket
8. When the aforementioned steps are not completed yet, do not apply force to buckle. Otherwise, there will be a
risk to damage the connector. When the connector cannot be smoothly buckled down, repeat the alignment
step.
Detaching a WisConnector
1. To disconnect the header from the socket, pull out in parallel with even forces.
Figure 10: Correct way: Applying even forces to detach the header from the socket
2. Avoid pulling out the header asymmetrically in the long-side direction.
Documentation Center
Figure 11: Wrong way: Applying uneven forces to detach the header from the socket
3. The short-side of the connector can be pulled out asymmetrically, but apply the force vertically and avoid
rotating the header.
Figure 12: Wrong way: Do not rotate the header
4. Avoid applying forces in a single corner.
Figure 13: Wrong way: Do not apply force in a single corner of the header
Assembling a WisBlock Module
WisBlock Core
A WisBlock Core module is designed to be installed on the CPU slot of the RAK19011 WisBlock Dual IO Base
Board with Power Slot. As shown in Figure 14, the location is properly marked by silkscreen. Follow carefully the
procedure defined in attaching a WisConnector section in order to attach a Core module. Once attached, fix the
module with one or more pieces of M1.2 x 3 mm screws depending on the WisBlock Core.
Documentation Center

WisBlock Power
A WisBlock Power module is designed to be installed on the Power slot of the RAK19011 WisBlock Dual IO Base
Board with a Power Slot. As shown in Figure 15, the location is properly marked by silkscreen. Follow carefully the
procedure defined in attaching a WisConnector section in order to attach a Core module. Once attached, fix the
module with one or more pieces of M1.2 x 3 mm screws depending on the WisBlock Core.

WisBlock Sensor
A WisBlock Sensor module is designed to be installed on the sensor slot of the RAK19011 WisBlock Dual IO Base
Board with Power Slot. There are six (6) available sensor slots in the RAK19011 WisBlock Dual IO Base Board
with Power Slot. As shown in Figure 16, the location of the slots is properly marked by silkscreen. Follow carefully
the procedure of the section, attaching a WisConnector, to attach a WisBlock Sensor module. Once attached, fix
the module with an M1.2 x 3 mm screw.

WisBlock IO
A WisBlock IO module is designed to be installed on the IO slot of the RAK19011 WisBlock Dual IO Base Board
with Power Slot. There are two (2) IO slots in the RAK19011 WisBlock Dual IO Base Board with Power Slot. As
shown in Figure 17, the location is properly marked by silkscreen. Follow carefully the procedure of the section,
attaching a WisConnector, to attach a WisBlock IO module. Once attached, fix the module with three pieces of
M1.2 x 3 mm screws.

Disassembling a WisBlock Module
1. The procedure to disassemble any type of WisBlock module is the same. As shown in Figure 18, first, remove
the screws.
Figure 18: Removing screws from the WisBlock module
2. Once the screws are removed, on the PCB of a WisBlock module, there is a silkscreen that shows the correct
location where force can be applied. By applying even force under the marked area, the module can be

Figure 20: Applying even forces on the proper location of a WisBlock module to detach the module from the Base Board
Software Setup
The WisBlock Core is designed to be interfaced with other WisBlock Modules like sensors, displays, and other
interfaces. To make useful devices, you need to upload a source code to the WisBlock Core. Before you continue,
you should have already set up either an Arduino BSP or PlatformIO .
WisBlock Examples Repository
To quickly build your IoT device with less hassle, example codes for WisBlock Core are provided. You can access
the codes on the WisBlock Example code repository . The example codes on folder common are compatible
with RAK4631, RAK11200, and RAK11310 WisBlock cores.

Datasheet
WisBlock Dual IO Base Board with Power Slot Overview
RAK19011 is a WisBlock Dual IO Base Board with Power Slot board that connects WisBlock Core, Wisblock Power, and WisBlock
Modules. It has one slot reserved for the WisBlock Core module, one slot for the Wisblock Power module, two IO slots, and six sensor slots A to F
for WisBlock Modules. Also, there are two 2.54 mm pitch headers that expose all key input-output pins of the WisBlock Core including UART, I2C,
SPI, and many IO Pins.
WisBlock Modules are connected to the RAK19011 WisBlock Dual IO Base Board with Power Slot via high-speed board-to-board connectors.
They provide secure and reliable interconnection to ensure the signal integrity of each data bus. A set of screws are used for fixing the modules,
which makes it reliable even in an environment with lots of vibrations. Additionally, it has a user-defined button.
If you can't find a module that fits your IoT requirements, use the standard connectors of WisBlock to develop your specific function module.
WisBlock supports open-source hardware architecture and you can find tutorials showing how to create your own Awesome WisBlock module.
