1. Hardware Environment Setup
The required equipments are as follows:

• 1 x Nordic nRF54L15-DK: PCA10156(1.0.0)
• 1 x AN54LV-DB-15 (Raytac nRF54L15 module Development Board)
• 1 x IDC Ribbon Cable
• 2 x USB Type-C Connection Cables

* Reminder: The "Nordic nRF54L15-DK" and "Raytac AN54LV-DB-15 Development Board" must be used together to proceed with application development and flashing firmware into the Raytac AN54LV-DB-15 development board.

Setup Steps:
Step 1: Connect the J-Link on the Nordic DK with the AN54LV-DB-15 using the IDC ribbon cable.

Make sure to match the red side of the IDC ribbon cable with "1" printed on the AN54LV-DB-15's J-Link socket.

Step 2: Use the Type-C USB cables to supply power to both the nRF54L15-DK and the AN54LV-DB-15.

The outcome should be same as the picture above.

Setup Steps:
Step 1: Download the latest version of nRF Connect for Desktop. Choose the Windows 64-bit - version 5.3.1 installer (nrfconnect-setup-5.3.1-x64.exe). Once finished, you will see " nRF Connect for Desktop" on your PC.

Step 2: Download the latest version of nRF Command Line Tools. Choose the Windows X86 64 - version 10.24.2 installer (nrf-command-line-tools-10.24.2-x64.exe)

* Reminder: During the installation of the above two programs, a window may pop up prompting that SEGGER J-LINK needs to be installed or updated concurrently.

If you’re initiating Segger Embedded Studio (SES) application, please check the guideline here(Click me)\

Step 3: Download the latest version of Visual Studio Code (VS Code). Choose Windows VSCodeUserSetup-x64 version 1.122 (VSCodeUserSetup-x64-1.122.1.exe). Once complete, you will see "Visual Studio Code" on your PC.

Step 4: After installation is complete, you can verify the installed packages in your PC's Control Panel under "Programs and Features":

3. Software/Firmware Application Development
You can develop application programs within the VS Code IDE development environment.
Below steps are how to install and select your target SDK version (nRF Connect SDK v3.3.0 in this article):

Step 1: Launch "VS Code"-> Select "nRF Connect" icon/extension on the side menu.

Click "Manage SDKs" and then select "Install SDK".

Step 2: Select "nRF Connect SDK".

Step 3: You will see several available versions of nRF Connect SDK vx.x.x. It is highly recommended to choose and install NCS v3.3.0 or later. In this guide, we select nRF Connect SDK(NCS) v3.3.0.

Step 4: Before starting the download for (NCS)v3.3.0, confirm your preferred target installation pathway.
By default, it is configured to c:\ncs\v3.3.0. Press 'Enter' to confirm.

Step 5: Once the nRF Connect SDK v3.3.0 environment setup finishes successfully, open the Bluetooth sample folder and select the "peripheral_uart" application template, then click "Open".

Step 6: In the "nRF Connect" layout, go to "Applications" --> "Add build configuration".

Under "Board target", look up and select "nrf54l15dk/nrf54l15/cpuapp" --> "Generate and Build".

* Note: You can also choose the board name “raytac_an54lv_db_15/nrf54l15/cpuapp” for subsequent building and development.

After completing the configuration, you will see "Build complete".

Step 7: Compilation completed. Once completed, a binary file named "zephyr.hex" will be generated in your "build" directory.

Step 8: Under the "ACTIONS" interface, you can switch between Build, Debug, and Flash functionalities dynamically.

Build

Debug

Flash

Step 9: CRITICAL BEFORE FLASHING/DEBUGGING: You have to change the VDD voltage configuration on the nRF54L15-DK board to 3.3V.

To do this: Launch "nRF Connect for Desktop" -> choose "Board Configurator" -> click "Open"

Change the VDD target selection value to "3.3V" -> click "Write config".

---

4. Flashing / Programming
The nRF Connect SDK (NCS) natively supports direct programming.
You can utilize the "Programmer" application tool to flash the compiled zephyr.hex binary file onto the target chip.
The exact procedure is detailed below:

Step 1: Open "nRF Connect for Desktop" -> select "Programmer" and click "Open".

Click "Select Device" and choose "nRF54L15DK".

Click "Add file".

Step 2: Select your compiled target ".hex" file.

Click "Erase & write" to initiate the programming/flashing process.

While flashing, a progress diagonal pattern will display on the right-hand panel.

When the LOG shows a "completed" status text, it means that the programming/flashing is successfully done.

Step 3: After the flash operation completes, you can download the "nRF Connect for Mobile" app to scan and verify that the Raytac AN54LV-DB-15 development board is advertising normally.

Raytac's Impact on the Zephyr Ecosystem - Little Module, Huge Potential

 

In this article, Stanley Huang, MSc, Deputy Manager of Firmware Development at Raytac, shares insights on how Raytac’s modules and development kits strengthen the Zephyr ecosystem.

[Stanley Huang, New Taipei City]

When we talk about open-source platforms like Zephyr RTOS, most people immediately think of major chip manufacturers such as ST Micro, NXP, or Nordic. But to me, what truly makes Zephyr famous amongst the developer community is through modules that developers can actually touch: those they can instantly plug in and start using right away. In these terms, Raytac is one of the most underrated and important contributors in this ecosystem.

Raytac Modules Make Zephyr More Accessible

Instead of being a chip vendor, we specialize in producing high-quality, globally certified modules - especially Bluetooth and Wi-Fi modules based on Nordic chipsets, such as the AN7002Q, AN54LQ, AN54LV, MDBT53, MDBT50Q, and MDBT42Q.
All these modules are already certified with Regional RF compliances(FCC, IC, CE, KC, etc.) and the latest Bluetooth Specifications, offering developers the assurance of “plug and play” and “production-ready” solutions.
We assure that our modules have become one of the easiest platforms for Zephyr developers to test BLE functionality.

I paired Zephyr with Raytac’s MDBT50Q-DB-40 development board when I first applied Zephyr in a BLE Peripheral project . With a simple west build -b nrf52840dk_nrf52840 followed by flashing the firmware using J-Link or nRF Connect for Desktop, the BLE beacon immediately showed up on my phone. Clean, simple, noise-free, and developer-friendly - that's Raytac's style.

Modules play an invaluable role in product development

Many would say Raytac only makes modules and the real core is still Nordic’s SoC.
But I believe that in an open-source system like Zephyr, the hardware that helps your project runs first is that which contributes the most.
Our Zephyr-registered development kits eliminate the hassles of manual soldering, regulatory certification, and antenna design, allowing engineers to fully focus on developing applications based on Zephyr.
They can run Zephyr’s BLE peripheral, central, GATT, and HCI samples directly on the Raytac kits that act as a one-stop hardware solution.
In many ways, Raytac has pushed Zephyr’s usability a significant step forward.

Raytac Also Expands Zephyr’s Application Horizon

Many of Raytac’s modules are ultra-compact- ideal for wearables, smart sensors, and low-power beacons…etc. These are the scenarios where Zephyr excels, and Raytac’s modules provide the physical platform to enable companies to build their "dream devices".
When running Zephyr on a tiny module like the AN54LV-15, developers will be amazed that something smaller than a piece of corn kernel can run a full RTOS, manage the BLE stack, trigger timers, drive I2C sensors, and even connect to the cloud, all by itself.  This combination doesn’t just make development easier - it inspires developers to realize that: “they can build their projects using Raytac's hardware.”

Raytac may not be the star, but we're always ready for you

On Zephyr’s main stage, companies like Nordic, STM, and Intel take the spotlight, but Raytac plays an essential supporting role - supporting the performance from behind the scenes. We offer stable, high quality, and low-power platforms, giving every line of Zephyr code a place to run and every feature a cornerstone.
Our greatest value lies in helping developers skip antenna design and RF interference concerns - so they can jump right into the Zephyr ecosystem with ease.

Our products deliver the reliability you need and the efficiency you expect.

We invite you to explore more about how Raytac supports the Zephyr ecosystem and discover our range of development kits and modules designed for seamless integration.
