You may want to consider for future development other boards such as the NanoPI Neo Air and other similar H2/3 based boards. Availability aside, some folks at Armbian forums have done experiments with cpu throttling and the results are very promising: H2 and H3 CPU are a lot faster than the BCM in the RPI but can be optimized to draw less power. If you get one of these boards, don't use the images at the manufacturers site but go straight to Armbian where they host highly optimized images for most known boards.
