Mmh... I think that the LicheeRV Nano has kind of more value to it.

Around 20 bucks for the Wifi variant. 1GHz, 256MB RAM, USB OTG, GPIO and full Linux support while drawing less than 1W without any power optimizations and even supports < 15$ 2.8" LCDs out of the box.

And Rust can be compiled to be used with it...

Take a look at the `best-practise.md`.

It is also the base board of NanoKVM[1]

I think the ace up the sleeve is PIO; I've seen so many weird and wonderful use cases for the Pico/RP-chips enabled by this feature, that don't seem replicable on other $1-class microcontrollers.

		I'd rather have the Linux SOC and a $0.50-$1 FPGA (Renesas ForgeFPGA, Gowin, Efinix, whatever) nearby.

		Wow thanks, this is definetely something I have to investigate. Maybe the Sipeed Maix SDK provides something similar for the LicheeRV Nano. I'm currently prototyping a tiny portable audio player[1] which battery life could benefit a lot from this. 1: https://github.com/sandreas/rust-slint-riscv64-musl-demo
