+
+The [Heltec HTCC-AB01 (V2) ](https://heltec.org/project/htcc-ab01-v2/) is a development board based on the ASR6052, which has an integrated PSoC® 4000 series MCU (ARM® Cortex® M0+ Core) and SX1262 transceiver. It features Arduino compatibility, an ultra low power design and an onboard SH1.25 for lithium batteries or solar panels.
+
+In this guide, we will set this module up for usage in the Arduino IDE and use an example code to connect it to {{% tts %}}.

+
+## Installing CubeCell Framework
+
+In order to use the CubeCell in Arduino, we need to install a framework created by Heltec.
+
+Download the latest release of the [Arduino Software (IDE)](https://www.arduino.cc/en/Main/Software), [install](https://www.arduino.cc/en/Guide) it on your operating system and run it.
+
+Open Arduino IDE, and click **File**->**Preferences**->**Settings** and click the button next to **Additional Boards Manager URLs**.
+
+{{< figure src="boards-manager.png" alt="">}}
+
+In a new line, enter `https://github.com/HelTecAutomation/CubeCell-Arduino/releases/download/V1.5.0/package_CubeCell_index.json` and click **OK**.
+
+{{< figure src="board-url.png" alt="">}}
+
+Click the **second icon in the left-hand menu** or select **Tools**->**Board**->**Boards Manager**, then search **Heltec** in the search field, select the latest releases and click **Install**.
+
+{{< figure src="install-board.png" alt="">}}
+
+## Connecting the Device
+
+Connect the board to your computer with a high quality USB-C cable.
+
+Click the **Select Board** drop down (or go to the **Tools** menu) and select the right COM port and board.
+
+{{< figure src="ab01-select.png" alt="">}}
+
+Then go to the **Tools** menu and you will see a couple of options. Let's run through the important ones that you have to check:
+
+- LORAWAN_CLASS – **Class A** (for more info check [here](https://www.thethingsnetwork.org/docs/lorawan/classes/))
+- LORAWAN_DEVEUI – **Generate by ChipID** (which generates a DevEUI based on the ASR650x's unique Chip ID)
+- LORAWAN_NETMODE – **OTAA**
+- LORAWAN_REGION – **Select the region your device is operating in.**
+
+If you want to know what the other options do check [here](https://docs.heltec.org/en/node/asr650x/asr650x_general_docs/running_sample.html#correctly-config-the-tools-menu).
+
+Then go to **File -> Examples** and you should see a separate section for the Heltec board. Select **LoRa -> LoRaWAN -> LoRaWan**.
+
+Once the file is open, upload it and when it is done uploading, open the Serial Monitor. Set the baud rate to `115200`. If no information shows up you might need to press the **Reset** button on the Heltec board itself.
+
+{{< figure src="ab01-serial.png" alt="">}}
+
+From the information that shows up, copy the **DevEui**, as you will need it in the next step.
+
+## Onboarding to {{% tts %}}
+
+The device can be onboarded using the **Device Repository** or **manually**.
+
+The [LoRaWAN® Device repository](https://github.com/TheThingsNetwork/lorawan-devices) comprises over 800 end-device profiles, including the AB01, which enables quick and easy registration with {{% tts %}}.
+
+In the **End device type** section, under **Input method**, select either the **Select the end device in the LoRaWAN Device Repository** or **Enter end device specifics manually** option. The [Onboarding devices without QR codes]({{< ref "/devices/adding-devices/#onboarding-devices-without-qr-codes" >}}) section of the [Adding Devices]({{< ref "/devices/adding-devices/" >}}) guide explains this procedure in detail. Following details are AB01-specific:
+
+- End device brand: **HelTec AutoMation**
+- Model: **HTCC-AB01(Class A OTAA)**
+- Hardware Ver.: **Unknown ver.**
+- Firmware Ver.: `1.0`
+
+{{< figure src="ab01-register.png" alt="Settings for registration through device repository" >}}
+
+For the Provisioning information, enter the following details:
+- JoinEUI: `0000000000000000`
+- DevEUI: **The DevEui that was previously copied from Arduino IDE Serial Monitor.**
+- AppKey: **Generate by clicking the Generate button.**
+
+{{< figure src="ab01-prov-info.png" alt="Settings for provisioning information" >}}
+
+After configuring your device, select the **Register end device** button.
+
+If you prefer onboarding **manually**, in the **End device type** section, under **Input Method**, select the **Enter end device specifics manually** option. The [Manually adding devices]({{< ref "/devices/adding-devices/manual/" >}}) and [Over the Air Activation (OTAA)]({{< ref "/devices/adding-devices/manual/otaa/" >}}) guides explain this procedure in detail. Following details are specific to the AB01:
+
+- LoRaWAN version: **LoRaWAN Specification 1.0.2**
+- Regional parameters version: **RP001 Regional Parameters 1.0.2 revision B**
+
+After configuring your device, select the **Register end device** button.
+
+{{< figure src="manual-register.png" alt="Settings for manual registration" >}}
+
+
+## Configuring the Device
+
+The device is now registered with {{% tts %}}, but it still needs lacks the AppKey info in order to connect.  
+
+Go back to your code, and at the top you should see these lines:  
+
+```cpp
+/* OTAA para*/
+uint8_t devEui[] = { 0x22, 0x32, 0x33, 0x00, 0x00, 0x88, 0x88, 0x02 };
+uint8_t appEui[] = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
+uint8_t appKey[] = { 0x88, 0x88, 0x88, 0x88, 0x88, 0x88, 0x88, 0x88, 0x88, 0x88, 0x88, 0x88, 0x88, 0x88, 0x66, 0x01 };
+```
+
+In {{% tts %}}, under **Activation Information**, click the **eye** icon next to **AppKey** and then selecting the **</>** icon. Then copy the AppKey by clicking the **Copy to clipboard** button.
+
+Replace the AppKey string between the brackets in your code with the AppKey copied from {{% tts %}}.  
+
+Now upload the code again to your device.
+
+## Monitoring Live Data
+
+When your device is registered, select the **Live Data** tab to view all messages exchanged between the end device and {{% tts %}}.
+
+{{< figure src="live-data.png" alt="Live data tab" >}}
