Cortex M4F + Cortex M0, dual bands (2.4GHz and 5GHz) WiFi, BLE, it seems enough to run MicroPython.

which flash and RAM sizes are available?

That has 512KB SRAM (Optional 4MB PSRAM) for Cortex-M4F, QSPI flash (similar RP2040).

That support Arduino currently.

Thanks. I had seen that. So the question remains, which actual Flash size is available in the module at AliExpress, which your referenced.

I guess 16Mbit (not ensure),

This is MicroPython implement on RTL8722DM (4MB PSRAM),

SeeedStudio's RTL8720DN boards have so far always supplied firmware as a blob, but it's good to see these boards open up more. With a 200 MHz Cortex-M4, 512 KB SRAM (+ optional PSRAM, depending on model) and SPI flash storage, they look handy. There's one in the SeeedStudio Wio Terminal that the SAMD51 port folks are looking at, but so far it's been inaccessible from MicroPython.

I'm not sure how available these are. SeeedStudio are out of stock of the module, and AliExpress availability numbers are some of the greater works of fiction ever made.

RTL8720DN on Wio Terminal seems use as wireless connectivity co-processor, not running MicroPython.

I see that realtek has a MicroPyhton port for the 8722 device. It should be possible to use much from that port.

I know, but so far it's a complete blob: you can't access it from anything but the Arduino IDE
