ESP32-S3 N16R8 is <$5 on aliexpress:
- Dual-core Xtensa 240 MHz
- 16 MB NOR flash (eXecute-in-place supported)
- 8 MB (PS)RAM
- Wi-Fi 2.4 GHz 802.11n, Bluetooth
As well as Zephyr, NuttX RTOSes, MicroPython.As a fun of Rust, one thing that saddens me is knowing these things would be difficult to achieve with a Rust compiler, given the language seems to be vastly more complex.
Unless someone created a subset of Rust without (some?) safety checks, I guess.
