Community

In 2018 Rust community has created an embedded workgroup to help drive adoption in the Rust ecosystem.

• Embedded WG, including newsletters with progress updates.

• You can usually find the members of the embedded WG on the #rust-embedded channel (server: irc.mozilla.org).

• embedded.rs Telegram chat about Rust for microcontrollers in Russian language.
