I'm planning on an extremely minimal focuser using a 28BYJ-48 motor driven with ULN2003 for an SCT telescope. I will power both the motor and Arduino with the 5V USB supply and put everything inside the motor housing. That way the only cable is the USB cable from my powered USB hub built into the ASI294 Pro camera. Essentially a clone of the ASI 5V EAF. I know all the warnings about doing this but I know how to properly distribute the power to make this work and am not concerned.
Since I want it to be physically as small as possible I'd like to try using a DFRobot Beetle as the controller instead of an Arduino Nano. The specs say it should work and the code compiles fine in the Arduino IDE. I'm wondering if anyone has tried anything similar. I have a Beetle board on order and will update this thread on my success/failure.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Will look forward to hearing the results.
