Murata Type 1LD EVB Development Board

Murata and MicroEJ collaborated to support the ultra-small Wi-Fi + Bluetooth combo module through a specific development board, Type1LD EVB MicroEJ is providing its leading trusted Virtual Execution Environment (VEE), mixing C and Java technologies for IoT application development.

The Murata Type 1LD module is small size (8.9 x 7.8 x 1.2 mm), dedicated to highly integrated IoT devices using a single processor for both communication and software applications.

Type 1LD module is based on CYW43438 combo chipset + STM32F412 MCU, which supports Wifi 802.11b/g/n + Bluetooth 4.1.

Get Started: VEE Development on Murata Type 1LD EVB

Develop your custom VEE on Murata Type 1LD EVB development board with MicroEJ Software Development Kit.

Follow the steps to learn how to create and enhance a MicroEJ architecture to better answer your needs and start prototyping your embedded device. In case you are not familiar with MicroEJ, please visit Discover MicroEJ to understand the principles of our technology.

1 – Download MICROEJ SDK

MICROEJ SDK is an IDE built on Eclipse for creating feature-rich applications for MicroEJ Virtual Execution Environment (VEE).

Supported Operating System

MICROEJ SDK runs on the following operating systems: Windows (7–8-8.1-10), Linux, Mac OS X)

A Java™ Runtime Environment 8 is needed on your host computer for running MICROEJ SDK. Download Java™ Runtime Environments


Download the installer package corresponding to your host computer OS (about MICROEJ SDK download).

Donwload MICROEJ SDK Dist. 21.11

2 – Install MICROEJ SDK

  • Unzip the downloaded installer package, if needed.
  • Run the unzipped executable file.
  • On Windows, accept the administrator privileges elevation.
  • Follow the installer steps.
  • Proceed to the next step.

3 – Activate Your License

MICROEJ SDK requires to be activated. Before going further, an evaluation license is required.

Get your UID

  • Download the Reference Implementation
  • Unzip the archive in the folder of your choice.
  • Start MICROEJ SDK.
  • Select a workspace. If you are not familiar with Eclipse workspaces, select the default one and press OK.
  • Select the MicroEJ repository where to import MicroEJ architectures from. If you are not familiar with MicroEJ repositories, select the default one and press OK.
  • Wait until MicroEJ Repository is initialized.
  • Select File > Import > MicroEJ > Architectures and click on Next>.
  • Select and browse the previously unarchived folder for MicroEJ Architecture files (select the directory platformArchitecture and import everything).
  • Follow the installation process.
  • Select the Window > Preferences > MicroEJ > Architectures menu.
  • Click on one of the available architectures and press Get UID.
  • Copy the UID. It will be needed when requesting a license.

Generate Your Activation Key

  • Go to
  • Click on Create a new account link.
  • Create your account with a valid email address. You will receive a confirmation email a few minutes after. Click on the confirmation link in the email and login with your new account.
  • Click on Activate a License.
  • Set Product P/N: to 9PEVNLDBU6IJ.
  • Set UID: to the UID you generated before.
  • Click on Activate.
  • The license is being activated. You should receive your activation by email in less than 5 minutes. If not, please contact
  • Once received by email, save the attached zip file that contains your activation key.


  • Go back to MICROEJ SDK.
  • Select the Window > Preferences > MicroEJ menu.
  • Press Add....
  • Browse the previously downloaded activation key archive file.
  • Press OK. A new license is successfully installed.
  • Go to Architectures sub-menu and check that all architectures are now activated (green check).
  • Your MICROEJ SDK is successfully activated. Proceed to the next step.

4 – Create Your First VEE

  • You are a C developer.
  • You want to create a custom MICROEJ VEE for your target hardware.
  • Inside the MICROEJ SDK select File > Import > General > Existing Projects into Workspace and click on Next>.
  • Select and browse the previously unarchived folder for a MICROEJ VEE sources file (e.g. [board]-[uid]
  • Select all Eclipse projects. Press Finish. The MICROEJ VEE sources are successfully imported.
  • Now you need to build it.
  • Provided that you installed the MICROEJ Architectures (see. step 2 of this getting started page), open the .platform file in the Murata-Type1LD-EVB-configuration project.
  • In the build section of the .platform file, click on Build Platform.
  • Wait for the build to finish, a new MurataType1LD-SingleApp-CM3_GCC48-X.X.X project should appear.
  • That’s it! You have build your first MICROEJ VEE. Now it is available to execute MICROEJ examples.

For this board you have to install up-to-date drivers for USB Serial and JTAG from Cypress. Follow the installation described here.

5 – AWS IoT Core Example

  • Get back your AWS IoT Core example from GitHub.
  • Follow the at the root of the repository folder.

You should specify the name of your default wifi interface, in the file Add in a new line in this file.

6 – Bluetooth Example

  • Download the following archive Bluetooth Example.
  • In the same MICROEJ SDK worspace you imported the MICROEJ VEE sources in.
  • Import the project from the previously downloaded archive, File > Import > General > Existing Projects into Workspace and click on Next>.
  • Right-click the MicroEJ project com.microej.example.bluetooth.hello.
  • Then Run As > MicroEJ Application.
  • Choose the Main class.
  • Select the MurataType1LD-SingleApp-CM3_GCC48 2.0.0 VEE.
  • It will instanciate a Run Configuration, you can stop the simulation.
  • Edit the newly created Run Configuration.
  • Configure the Execution mode to Execute on Device, Core Engine Default and Settings Build and Deploy
  • Click on Run button.
  • This will compile the application into the Murata-Type1LD-EVB-bsp project.
  • To build and flash the final binary: open the Build Targets view. (Ctrl + 3 in MICROEJ SDK then type Build Targets).
  • Execute the snip.microej-MurataType1LD-FreeRTOS-LwIP-SDIO download download_apps run target.
  • This will deploy an application that will periodically send a message to devices connecting to the board through Bluetooth.
  • To view the message you can use the Bluetooth Companion, an Android application that allows the connection to the ESP32-WROVER and display of such message.
  • Download the .apk file here.
  • Consult the documentation for installing APK files for your phone.
