I am urging everyone who wants to do this to see if they can't first do what they need with a small board like an ESP32. Their energy usage is a small fraction, they cost ones of dollars, and they're sufficient for a whole lot. If you're of the Python persuasion, many boards support both MicroPython and CircuitPython.
It's worth looking into for the cost savings on initial purchase and ongoing power draw.
