Prerequisite

What Do You Need?

Before going through each and every step on using the RAK16002 WisBlock Coulomb sensor module, make sure

to prepare the necessary items listed below:

Hardware

RAK16002 WisBlock Coulomb Sensor Module

WisBlock Base

Your choice of WisBlock Core

USB Cable

Li-Ion/LiPo battery (optional)

Solar charger (optional)

Software

Arduino

Download and install the Arduino IDE .

To add the RAKwireless Core boards to your Arduino Boards Manager, install the RAKwireless Arduino BSP .

Product Configuration

Hardware Setup

RAK16002 is a Coulomb sensor module based on LTC2941IDCB that features programmable high and low

thresholds for the accumulated charge. If a threshold is exceeded, the device communicates an alert by setting a

flag in the internal status register. It can measure the battery charge state in battery-powered IoT devices. For

more information about the RAK16002, refer to the Datasheet.

The RAK16002 WisBlock Coulomb sensor module can be mounted on the IO slot of the WisBlock Base board, as

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

this example, we use J2 shorted pin1 and pin2 (internal charge/load) and J4 shorted pin1 and pin2 (internal battery

measurement). See Figure 2 for jumper and battery connector settings.

Assembling and Disassembling of WisBlock Modules

Assembling Procedure

Documentation Center

The RAK16002 module can be mounted on the IO slot of the WisBlock Base board, as shown in Figure 3. Also,

always secure the connection of the WisBlock module by using compatible screws.

Figure 3: RAK16002 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.

Documentation Center

NOTE

If you will connect other modules to the remaining WisBlock Base slots, check on the WisBlock Pin

Mapper tool for possible conflicts.

Now, you can connect the battery (optional) and USB cable to start programming your WisBlock Core.

Software Configuration and Example

In our example, you can measure voltage and DC current from a sensor.
