I’ve been working through Google’s Comprehensive Rust and, for the past couple of weeks, the Bare Metal Rust standalone course that uses the (excellent) micro:bit v2 that has a Nordic Semiconductor nRF52833 (an ARM Cortex-M4; interestingly its USB interface is also implemented using an ARM Cortex M0).

There’s a wealth of Rust tutorials for microcontrollers and I bought an ESP32-C3-DevKit-RUST-1 for another tutorial and spent some time with my favorite Pi Pico and a newly-acquired Debug Probe.
