The nano is basically a thin uno and has little storage for large projects, and OPs list of sensors is large. Something like three hundred cell limit. Its just not going to fit. I've played with drivers using ulisp and its fun and very fast on an adafruit SAMD51 board with plenty of storage. A Metro M4 Gran Central is a lovely dev board but too large for OP to launch. Maybe an adafruit M4 feather board would work. I've not used one but its supposedly plug and play with ulisp, so I've heard. I've never used one, but in theory a mattairtech.com product seems like what OP wants. ulisp should compile its just another SAMD51 board, right? And its available with some of the sensors OP wanted onboard. Note that "never used one" means OP will literally be breaking new ground. All I'm sure of its a physically very small SAMD51 board and I can't see any obvious reason ulisp wouldn't work. The future of embeded dev is probably FPGA for custom hardware and interfaces with lisp or similar HLL (Straight up Clojure getting embedded?). No I don't mean tomorrow future, but maybe 2030.
