Good morning, this is AtomVM Daily for June 3rd, 2026.
AtomVM has taken a major step forward in embedded connectivity with the addition of USB CDC port drivers spanning three key microcontroller platforms. This represents the most significant expansion of serial communication capabilities we've seen in recent development.
The centerpiece is pull request 2301, which delivers USB CDC drivers for ESP32, Raspberry Pi Pico, and STM32 platforms. This broad implementation touches multiple build systems and updates both the changelog and programmer's guide, indicating a substantial feature addition that developers can immediately leverage.…
For developers working with embedded Erlang applications, this means consistent USB serial communication regardless of whether you're deploying to ESP32 modules, Pico boards, or STM32 devices. The unified approach should simplify code portability and reduce platform-specific communication handling.
The development team also addressed CI infrastructure stability with pull request 2327, bumping timeout values for macOS workflows. While this appears minor, it signals awareness of build reliability issues that could slow development velocity if left…
