RAK19016 WisBlock 5-24 V Power Slot Module Quick Start Guide

Prerequisite​

What Do You Need?​

Before going through each and every step on using the RAK19016 WisBlock 5~24 V Power Slot Module, make sure to prepare the necessary items listed below.

Hardware​

Software​

Arduino​

Product Configuration​

Hardware Setup​

RAK19016 should be attached to the power slot connector of WisBlock Base board with power slot. The 5~24 VDC 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.

NOTE

The voltage of the battery must not exceed 4.3 V.

RAK19016 Supplemented by RAK5804 to Support WisBlock Core Reprogramming​

Since there is no USB connector on RAK19016, the only way to upload the code is by using RAK5804.

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.

Disassembling Procedure​

The procedure in disassembling any type of WisBlock module is the same.

  1. Start by removing the screws.

  1. Once the screws are removed, check the silkscreen of the module to find the correct location where force can be applied.

  1. 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 524 VDC input can simultaneously be connected to provide power to all WisBlock modules. The 524 VDC goes to a buck converter with 4.4 VDC output which is higher than the max 4.2 VDC of LiPo battery. 5~24 VDC 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
  • Improper handling of the battery can be harmful.
  • 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 macro definitions 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.
