M5Stack ESP32-S3 kits

How well does Espruino support M5Stack's ESP32-S3 devices like the fun little $30 CardPuter?

• 512 KB SRAM - for data and instructions, running at a configurable frequency of up to 240 MH
  
• 16 KB SRAM in RTC - can retain data in Deep-sleep mode
  
• 4 Kbit eFuse - reserved for user data, such as encryption key and device ID
  
• SPI, Dual SPI, Quad SPI, Octal SPI, QPI and OPI interfaces that allow connection to multiple flash and external RAM

Edit:
Searching the forum, I found this discussion about a community fork of Espruino for S3, with an interesting exchange about the business side of Espruino, where I fully understand Gordon's position.

So the answer appears to be: it's not supported, and the S3 fork is still young but might work.

This quote gives me some hope though: "I really love the ESP32 chips - I think they're fantastic (especially the RISC-V ones), and I do want to find a way to support them properly."

So the answer appears to be: it's not supported, and the S3 fork is still young but might work.

Yes - there's a board file called ESP32S3_IDF4.py and if you build that then it should work - although you'd have to figure out how to access the screen/keyboard/etc directly from JS, but that's probably not the end of the world as it seems reasonably well documented

Thanks for the pointers! The CardPuter is in the mail, so I'll give it a go when it arrives. If something comes out of it, I'll update here.
