Overview
| 📝 NOTE: RAK19007 is the 2nd generation WisBlock Base board in same form-factor with RAK5005-O. There are minor differences on the two WisBlock Base boards with makes this guide compatible to both RAK19007 and RAK5005-O Baseboards. |
RAK5005-O WisBlock module is a motherboard that allows you to attach MCU, sensors, and IO modules through the standardized expansion connectors. These connectors provide a data bus interconnection between the modules attached to the baseboard.
This document explains the details related to the installation of modules into the RAK5005-O board. The following section discusses the general concepts to manipulate the WisConnector in any WisBlock module are explained. For the second one, it explains the installation details of each type of WisBlock module: Core, Sensor, and IO, and the last section explains how to remove a WisBlock module from the RAK5005-O baseboard.
WisConnector General Concepts
Attaching a WisConnector
The IO Connector is the interface between the RAK5005-O module and the WisBlock Core, Sensor, and IO modules. Before manipulating these modules, read the following instructions.
| 📝 NOTE: This document uses two arrows. Refer to Figure 1 for its representation. |
Align the connectors. Keep the header parallel and place it lightly in the corresponding lap joint of the socket.
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.
After the above alignment steps, the header and socket are matched, but still not buckled.
Apply forces evenly by pressing in parallel, then there will be a sound confirming the completion of the buckling.
In the process of buckling and applying force, avoid application of uneven force on both sides.
When the buckling process is completed, check that the header and socket are kept in parallel.
If after buckling, the header and socket are not in a parallel state (not fully assembled in one place), then press the even force on both sides of the long side to complete the correct buckling.
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
To disconnect the header from the socket, pull-out parallelly with even forces.
Avoid pulling out the header asymmetrically in the long-side direction.
The short-side of the connector can be pulled out asymmetrically, but apply the force vertically and avoid to rotate the header.
Avoid applying forces in a single corner.
Assembling a WisBlock Module
| 📝 NOTE: Read carefully the complete instruction first before trying to assemble a module. |
WisBlock Core
A WisBlock Core module is designed to be installed on the CPU slot of the RAK5005-O baseboard. As shown in Figure 13, the location is properly marked by silkscreen. Follow carefully the procedure defined in section 2.1 in order to attach a Core module. Once attached, fix the module with 4 pieces of M1.2 x 3mm screws.
WisBlock Sensor
| 📝 NOTE: The RAK1910 GPS module must be installed only on the front side of the RAK5005-O baseboard. The RAK1910 is a full-length module that use the space of two WisBlock IO module. |
A WisBlock Sensor module is designed to be installed on the Sensor slot of the RAK5005-O baseboard. There are four (4) available sensor slots in the RAK5005-O baseboard, two (2) on each side of the baseboard. As shown in Figure 14, the location is properly marked by silkscreen. Follow carefully the procedure of the previous section, Attaching a WisConnector, to attach a WisBlock Sensor module. Once attached, fix the module with a M1.2 x 3 mm screw.
WisBlock IO
A WisBlock IO module is designed to be installed on the IO slot of the RAK5005-O baseboard. There is a single IO slot in the RAK5005-O baseboard. As shown in Figure 15, the location is properly marked by silkscreen. Follow carefully the procedure of the previous section, Attaching a WisConnector, to attach a WisBlock Sensor module. Once attached, fix the module with three pieces of M1.2 x 3mm screws.
Disassembling a WisBlock Module
| 📝 NOTE: Read carefully the complete instruction first before trying to disassemble a module. |
The procedure to disassemble any type of WisBlock modules is the same. As shown in Figure 16, first, remove the screws.
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 detached from the baseboard. See Figures 17 and 18.
