It depends on what kind of connectivity do you need, and how fault tolerant you have to be. If you need mostly wifi/bluetooth, there's a very nice line of microcontrollers: ESP32. They have a lot of variants, so you can find the one you want. If you need IO pins, Arduino is the way to go. They too have lots of variants, with more pins, less pins, large, small, and they are very easy to program. If you need processing power, the RasPi variants are the ones you should use. They run Linux, they have beefy processors (for an embedded platform), lots of RAM, and are accessible too. STM have some industrial-grade microcontrollers too, and I believe you can program them with C. I have a STM Discovery in a drawer somewhere... Fault tolerance can be achieved using more than one board, and depending on the equipment you are controlling, you can use some combination of OR-gates or counters to define if you are activating it or not. As the boards are cheap, it won't be much expensive having 4 Arduinos giving the same input.

Greetings
I'm wanting to use micro controllers in more of an industrial setting. Don't want to spend the $$$$$$$$$$$ to get the officially hardened etc etc etc models.
Looking for information - - - - - there's piles on using Arduino, Raspberry Pi but they're not really developed for serious use (one point - - - - almost always have to add a cape or a shield to get real connectivity - - - - don't need the the hp waste that's RPi so I"d rather not use that . . . .) Trying to find other ucontroller boards - - - - can find plenty of SoB - - - - but not boards. Hoping to use open source tools for the programming and control.
Any suggestions as to where to look for this kind of stuff?
Am I wasting my time? (I hope not!!)
TIA

I have had great success with Arduino mega, mini and Adafruit Huzzah feathers. Not in industrial settings though. The Huzzahs are relatively inexpensive and have wireless built in. All can be developed with the Arduino IDE, which is tolerable.
I use the Huzzahs for indoor/outdoor Temp/Humidity/Pressure sensing, for tracking power consumption on my hydro and have used it for net enabled fan control and for, errr, cat feeding scheduling (Not a success, but due to the cat).
I bought all the micros at Creatron when it was open, and the odd purchase of ICs from Amazon has worked for me.
