I've been using ESP8266/ESP32 boards, but the RP2040 used in the Pi Pico looks interesting as it's cheap, dual-core, and has the PIO units on it. The Pico has weak network connectivity, but the RP2040 chip is showing up in other boards like the Arduino Nano RP2040 Connect, which has WiFi+BT. Haven't heard pricing or availability. (Other RP2040 boards are coming from SparkFun, Adafruit, and others). Could be an interesting option in a space that intersects with the ESP32 boards (looking forward to comparing ESP32 [Extensa] vs ESP32-C3 [RiscV] vs RP2040+Wifi+BT [ARM C-M0+] boards).

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

Regards
