- [@eldruin] released a platform-agnostic [driver for the PCA9685][pca9685-driver] PWM LED/Servo controller driver and published a [blog post][pca9685-blog-post] including a video of the device controlling RGB LEDs and several Servo motors simultaneously.

- [@nickray] released `salty` ([API][salty-api], [book][salty-book], [code][salty-code]), a library for fast Ed25519 signatures on Cortex-M4 and Cortex-M33 microcontrollers. It presents the `ed25519-dalek` API, but is self-contained and uses the fastest currently published field operations implementation, due to Bjoern Haase, based on the `UMAAL` DSP instruction `(a: u32, b: u32, c: u32, d: u32) -> (a * b + c + d): u64`. Testing is done on the `musca-b1` Cortex-M33 microcontroller, simulated in QEMU v4. Additionally, a C API is included.

- [@nickray] released `littlefs2` ([API][littlefs2-api], [code][littlefs2-code]), an idiomatic Rust API for the [`littlefs`][littlefs-upstream] filesystem for microcontrollers, modeled after `std::fs`. The upstream library claims to be resilient against power-loss, and supports features like dynamic wear-leveling with bad block detection, inline files for efficient use of storage, and custom user attributes on files and directories.
