Re: static ip in Stretch not quite working with my setup

I only use wifi. There is no LAN port on the router. In fact, there are no ports at all on the router. The mind boggles... Who would design a router that way? (Actually...if it really is a router, I'd bet that there is at least one port...the WAN port. Or if it is a combined modem/router there is e...

It's just the whole industrial application and custom I/O board that I was interested in.
As a concept or to go into a business? Once more, I can't emphasize enough that if you are interested in the CM, read the Compute Module forum. That's where the active CM discussions take place.

Tons of them. Google is your friend. Plus, of course, innumerable books. You could probably find college or "adult education" courses on it as well. If you have a local Coder Dojo or Code Club near by, pretend to be 10 years old and they'd probably teach it to you.

Re: Pi Zero

You can get displays up to about 3.5" that connect to a Pi through the GPIO block. With a Pi0 you'll have to solder the GPIO pins in yourself. To find displays, use your favorite search engine and look for small displays for Pis. I am personally rather fond of the 3.5" LCD from Neosec, but there are...

Re: Compute Module

I've actually never soldered anything before. So for the CM + an I/O board you need a power PCB? The power circuits are generally on the carrier board PCB. If you really want to move forward with a project of developing your own carrier board, I would suggest two things. First, buy an RPF/RPT devel...

So the CM is actually better than the RPi 3/B? (Note: I am reading the question as referring to the CM3. The CM uses the original Model B/Model A/A+/B+/Pi0/Pi0W(H) SoC...single core ARMv11, 700MHz to 1GHz, 512MB RAM with 4GB eMMC added.) Define "better". It's the exact same SoC. The exact same RAM....

The easiest approach is to (1) don't buy something sold as a "charger". Such a device is meant to charge internal batteries in cell phones at tablets. Since those batteries a spec'd at 3.7v, they will tolerate a major drop in charging voltage without problems. As a result, a charger will have poor v...
