Moddable SDK 4.9.0 contains improvements made between June 5, 2024 and July 18, 2024.

This release brings support for Moddable Six, our new development board! Moddable Six is our most powerful device, able to deliver advanced mobile-class user experiences on low-cost, compact embedded hardware. Here's just some of what it includes:

  • ESP32-S3 MCU, a dual-core 240 MHz CPU with built-in Wi-Fi and BLE
  • Bright, beautiful IPS display for flicker-free animation at 60 FPS
  • Low-latency multi-touch display
  • Audio speaker
  • 8 MB high-speed PSRAM
  • 8 MB high-speed flash storage
  • Qwiic connector
  • USB and serial

There's extensive technical documentation available for all the capabilities of Moddable Six. Dig into that to learn how to use the powerful hardware in your JavaScript projects.

Moddable Six is a significant upgrade to our most popular development board, Moddable Two. Moddable Six is available immediately at the same price as Moddable Two, starting at just $29.99. Check out the product page and order today.

Moddable Six is so much more powerful than Moddable Two that we created an all-new suite of examples to demonstrate what is now possible. Check out the Speaking Clock, Battery Monitor, and Smart Plug Schedule projects to see how Moddable Six brings mobile-class user experience to IoT products built with modern JavaScript.

Important: The Moddable SDK now recommends using ESP-IDF v5.2.2, the most recent production version of the Espressif SDK. This version contains major improvements to BLE and Wi-Fi compared to the previously recommended v5.1.2. Updating to ESP-IDF v5.2.2 is straightforward. For the vast majority of Moddable SDK projects, no changes to your JavaScript code are required. The Moddable SDK contains instructions for updating on macOS, Linux, and Windows.
