RAK Wis Blocks: Build Things, One Block At A time

arduino Nov 24, 2020

Introduction ✨

WisBlock is an amazing product built by the RAK company for the IoT industry. With its modular approach solutions are built like clicking blocks together to realize your ideas.

Delete this embedWisBlock series modules are not only for the rapid implementation of engineering prototypes, but it is also designed for massive production-ready applications.

I was part of the WisBlock beta testing team, and I received this WisBlock Premium kit from the RAK Wireless. Thanks, RAK Wireless ❤.

The Kit includes everything we need to develop an IOT application 🔥.

The WisBlock consists of WisBlock Base, WisBlock Core, WisBlock Sensor and WisBlock IO.

WisBlock Base → the block that the whole system is built on.
WisBlock Core → the processing unit with the microcontroller
WisBlock Sensor → the blocks with a variety of sensors
WisBlock IO → The blocks that extend the communication possibilities of the WisBlock.

WisBlock Base Board 🍪

WisBlock Core 🧠

The RAK4631 WisBlock LPWAN is a WisBlock Core module which delivers a powerful Nordic nRF52840 MCU with BLE 5.0 paired to the latest LoRa® transceivers from Semtech, the SX126x series.The module also includes a temperature-controlled crystal oscillator (TXCO) for correct operation across a wide range of temperature and bandwidth requirements as well as multiple communication interfaces including UARTs, I2C, SPI, ADC, USB and GPIOs.RAK4631 together with the RAK5005-O WisBlock Base module can be easily expanded with many available sensors and IO boards. This is the ideal LoRa® end node for battery and/or solar-powered applications in remote locations. It can be easily programmed with the Arduino IDE or the PlatformIO extension for IDE's like Atom, MS Visual Studio Code, or Clion.

Development 👨‍💻

Getting started with the WisBlock products is simple and straight forward. WisBlock support Arduino IDE and PlatformIO.Arduino IDE Setup1. Download Arduino IDEFirst, you need to download the Arduino IDE, Click here to download.

2. Download the WisBlock Board Definitions.To Add WisBlock on Arduino IDE we need to install board definition in the Arduino, for that open File -> Preference

https://downloads.rakwireless.com/Arduino/BSP/package_raknrf_index.json

Add this URL into the Additional Board Manager URLs.

those who have many boards definition, you can open the Additional Board Manager URLs, and past the URL on the bottom, then click and OK, then restart the Arduino IDE.3. Install WisBlock Core Board.Open the Boards Manager from Tools Menu. Tools -> Board -> Boards Manager

From the following window, search RAK and Install it.

Install RAKWireless nRF Board.

Note that, you need to connect the computer into the internet to install the board files.

After installation, click close..

Now, you can see the RAK Board's listed under the Arduino Board list.
