Product Configuration
Hardware Setup
RAK19016 should be attached to the power slot connector of WisBlock Base board with power slot. The 5 V to
24 V DC input voltage must be connected to the 3-pin screw terminal connector. The LiPo/Li-Ion battery can be
connected to the standard battery connector.
⚠ WARNING
RAK19016 only supports WisBlock Base boards with power slot. It is not compatible with all WisBlock
Base boards.
For more information about RAK19016, refer to the Datasheet.

Assembling and Disassembling of WisBlock Modules
Assembling Procedure
The RAK19016 module can be mounted on the power slot of the WisBlock Base board, as shown in Figure 3.
Also, always secure the connection of the WisBlock module by using compatible screws.

Documentation Center
Figure 3: RAK19016 mounting connection to WisBlock Base module
Disassembling Procedure
The procedure in disassembling any type of WisBlock module is the same.
1. First, remove the screws.
Figure 4: 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 5: Detaching silkscreen on the WisBlock module
3. Apply force to the module at the position of the connector, as shown in Figure 6, to detach the module from the
baseboard.

📝 NOTE
If you will connect other modules to the remaining WisBlock Base slots, check on the WisBlock Pin
Mapper tool for possible conflicts.
Battery Connector
Rechargeable Battery
RAK19016 supports a rechargeable Li-Ion/LiPo battery via the dedicated connector. The battery and external 5-
24 V DC input can simultaneously be connected to provide power to all WisBlock modules. The 5-24 VDC goes to
a buck converter with 4.4 VDC output which is higher than the max 4.2 of LiPo battery. 5-24DCV DC is the primary
power source and also charges the LiPo battery at the same time.
The matching connector for the rechargeable battery wires is a JST PHR-2 2 mm pitch female . A cable
assembly for the rechargeable battery connector is also available for purchase in RAK store .
⚠ WARNING
Battery 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.
Make sure the battery wires, both rechargeable and non-rechargeable, match the polarity on the
RAK19016 board. Not all batteries have the same wiring.
Software Setup
There is no software required to use RAK19016. But to control the two user LEDs and monitor the battery voltage,
it must be attached to a WisBlock Base and WisBlock Core.
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. The two user LEDs of RAK19016 can be accessed
using macrodefinitions LED_GREEN / PIN_LED1 for the green LED and LED_BLUE / PIN_LED2 for the blue
LED. For the battery voltage reading, WB_A0 is used.

Hardware
The hardware specification is categorized into six parts. It discusses the interfacing, pinouts, and their
corresponding functions and diagrams of the module. It also covers the electrical, mechanical, and environmental
characteristics that include the tabular data of the functionalities and standard values of the RAK19016 WisBlock
5-24V Power Slot Module.
Interfaces
RAK19016 WisBlock 5-24V Power Slot Module provides the following interfaces:
Three-pin Screw Terminal Connector
Battery Connector
LEDs - one for charging status and two for user
Reset button
📝 NOTE
RAK19016 doesn't have a USB connector. So when RAK19016 is used together with WisBlock Base
board with power slot, it is not possible to program the core (unless via SWD pins using external tools like
Jlink and RAKDAP1). If you want to program the WisBlock Core via USB, you need the RAK5804. Then
you can use the USB connector of RAK5804 to program the WisBlock Core.
