RAKwireless Arduino BSP
Product Configuration
Hardware Setup
WisBlock can integrate this module which makes it easy to build up an
environmental temperature and humidity data acquisition system.
For more information about the RAK1901, refer to the Datasheet.
The RAK1901 module gives information about:
- Environment Temperature
- Environment Humidity
RAK1901 module can be connected to any slot of WisBlock Base to communicate
with the WisBlock Core. It will work on SLOT A to D. Also, always secure the
connection of the WisBlock module by using compatible screws.

Assembling and Disassembling of WisBlock Modules Assembling
As shown in Figure 2, the location for Slots 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 2: RAK1901 connection to WisBlock Base
Disassembling
The procedure in disassembling any type of WisBlock module is the same.
First, remove the screws.
Figure 3: 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 4: Detaching silkscreen on the WisBlock module
3. Apply force to the module at the position of the connector, as shown in
Figure 5, 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. RAK1901 uses I2C communication lines, and
it can cause possible conflict especially on some IO modules.
After all this setup, you can now connect the battery and USB cable to start
programming your WisBlock Core.
Software Configuration and Example
The RAK1901 is a Temperature & Humidity sensor board that contains the SHTC3
chip. The SHTC3 is a digital temperature and humidity sensor designed
especially for battery-driven high-volume consumer electronics applications.
The device comprises a sensing element and an IC interface that communicates
through I2C from the sensing element to the application.
These are the quick links that go directly to the software guide for the
specific WisBlock Core module you use:

RAK1901 in RAK4631 WisBlock Core Guide
If you already installed the RAKwireless Arduino BSP , the WisBlock Core and example code should now be available on the Arduino IDE.
- First, you need to select the RAK4631 WisBlock Core.
- The Basic Sample Code for RAK1901 in Github will work on all WisBlock Core. You can open the example codes depending on your WisBlock Core, as shown in Figure 7.
Figure 7: Opening RAK1901 example code for RAK4631 WisBlock Core - Once the example code is open, install the SparkFun SHTC3 library by clicking the yellow highlighted link, as shown in Figure 8.
