That sounds like something the size of an ESP32.

Assuming your flash allows XIP (execute in place) so all that memory is available for your lua interpreter data, you should at least be able to run some code, but don't expect to run any heavy full applications on that. I don't know Berry but it sounds like a better fit for the scale of your device.

But sure, why not give it a try: Lua is usually easy to port to whatever platform, so just spin it up and see how it works for you!

It is a RP2040. We plan to eventually upgrade to RP2350B.
