Yes, there are several manufacturers starting to build products with the Pi processor, so it will be interesting to see what projects arise from them. I was thinking about Circuit Python, but the Pi website has great documentation on implementing Micro Python, so I think I'll start there first. Both / either would be great choices in my opinion

The great thing about Circuit Python is Adafruit has modules for all their sensors and displays etc.

Good thing I put an order in for 4 of the Pico's (grin). I can play with C/C++ on one, Micro Python on another, and Circuit Python on a third..... and one for spare in case something tragic occurs during the testing phase.....grin! $5.25CDN each, crazy price!
