Hi all at Sparkfun,
First thank you for all the amazing work you do! 
What follows is a feedback / customer wishlist, not a criticism - don’t take it negative!
A small user feedback: I “feel the pain” / am increasingly missing a bleeding-edge hi-performance low-power MCU of the latest generation. The Ambiq 3 BLUE in the Artemis line of product is amazing, but it is already 6 years since it was released in 2019 (time flies!). The newer equivalents (Ambiq 510 or STM32U5 (though it is a bit less power effective) in beefiest versions) have up to 10x or more the RAM, and many times the compute, while taking power use even down.
Any hope that SF could release a new line of products with one of these MCUs, or something similar? For several projects I am involved in (that have bought over 1000 artemis global trackers over the last few years), we are now feeling too tightly limited by the Ambiq 3 resources. I would love to stick to SF products as I am very happy with everything SF and I am very happy to support open source, but unfortunately if there is not an updated MCU release within a few months, I will have to choose another provider for the next generation of products I am involved in, which would be really sad 
(for example, I have now to consider using either nucleo board or ambiq development boards directly with either STM32U5 or Ambiq 510).
Again, not a criticism - just trying to share my experience so you are aware that there are such users out, as I would love to continue sticking to your products
