This release contains improvements to the Moddable SDK made between January 3, 2024 and February 1, 2024.

Highlights of this release include:

  • Moddable Display. Our latest hardware is also our most beautiful. Fully supported in this release.
  • Web Streams. Help explore the feasibility and potential of this powerful web standard on embedded devices.
  • OpenAI text-to-speech provides another high quality option that's easy to add to projects.
  • Bosch BME68x Visualizers for round displays (works in the simulator too). Learn how to use outline graphics to creatively visualize sensor data.
  • Many low-level improvements for nRF52 ports. The port that powers our ultra-low energy Moddable Four is more capable than ever.

New Hardware: Moddable recently launched the Moddable Display product line. Moddable Display is the beautiful way to bring your latest embedded JavaScript project from the workbench to the real world.

Documentation: All of the Moddable SDK documentation is available to read on moddable.com. We recently moved the site to a new hosting provider so browsing the documentation is fast.

Reminder: ESP-IDF v5.1.2 is now recommended for ESP32 development. Please see the January 2024 Release Notes for details on how to update.

  • Modules
    • OpenAI text-to-speech support using streaming MP3 audio. (Contributed by @stc1988)
    • New AW3641 flash-light driver (with example). Works with M5Stack Core-S3. (contributed by @NW-Lab)

    • Support TLS device certificates for Node-RED MCU Edition
  • ECMA-419
    • TCP socket on macOS no longer tries to look-up IP addresses using DNS. Fixes connection failures.

  • XS
    • xst (XS test tool)
      • Uses fdlibm for certain functions of the Math object to guarantee exact results across all platforms test (details). fdlibm is recommended, but not required, by ECMA-262.
