I would like to build a project with the Raspberry Pi Zero and the camera module. I'd like to write custom software to capture video, do minimal processing and send it on using wifi and/or bluetooth. The really small form factor is very important for me.
Unfortunately, as anyone interested in the RPI Zero would know, it is perpetually unavailable.
What are some alternative platforms that may be interesting for me to investigate that will allow me to do the same thing, hopefully with similar ease of development?
