RAK19002 WisBlock Boost Module Quick Start Guide

Prerequisite​

What Do You Need?​

Before going through each and every step on using RAK19002 WisBlock module, make sure to prepare the necessary items listed below:

Hardware​

Software​

Product Configuration​

Hardware Setup​

The RAK19002 is a step-up boost regulator module, part of the RAKwireless WisBlock Series. The module can supply 12 V / 50 mA and could be mounted on WisSensor slot of RAK5005-O. The output voltage of the module is controlled by WisBlock Core IO pin.

For more information about RAK19002, refer to the Datasheet.

RAK19002 module can be connected to Slot A, B, C, or D of WisBlock Base to communicate with the WisBlock Core. It will work on any of those slots, but you need to consider the specific pin assigned on that slot to use the RAK19002. The table below shows the default IO pins used:

SLOT ASLOT BSLOT CSLOT D
IO1IO2IO3IO5

Also, always secure the connection of the WisBlock module by using the compatible screws, as shown in Figure 1.

Assembling and Disassembling of WisBlock Modules​

Assembling​

As shown in Figure 3, the location for Slot A, B, C, and D are properly marked by silkscreen. Follow carefully the procedure defined in RAK5005-O module assembly/disassembly instructions to attach a WisBlock module. Once attached, carefully fix the module with one or more pieces of M1.2 x 3 mm screws depending on the module.

Figure 4241: Module connection to WisBlock Base
Disassembling​

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

  1. First, remove the screws.
Figure 4242: Removing screws from the WisBlock module
  1. Once the screws are removed, check the silkscreen of the module to find the correct location where force can be applied.
Figure 4243: Detaching silkscreen on the WisBlock module
  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 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.

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 are matching the polarity on the WisBlock Base board. Not all batteries have the same wiring.

Software Configuration and Example​

For RAK19002, the default accessible IO pin assignments are defined as follows which are used on different connection slots:

  • WB_IO1 for IO1 on SLOT A
  • WB_IO2 for IO2 on SLOT B
  • WB_IO3 for IO3 on SLOT C
  • WB_IO5 for IO5 on SLOT D
NOTE
  • The IO pin MUST be set to HIGH to enable the RAK19002 Boost module.
  • The SLOT B is not recommended because the IO2 pin is used to control power supply 3V3_S on RAK5005-O WisBase.
  • The maximum recommended current is 50 mA ( VIN=3.3 V ).
