Is anyone aware of any development work to port MicroPython to the ESP32-S2? There seem to be some significant differences, like having one CPU core instead of two, and USB OTG support, both of which might need a reasonable amount of work. It has less RAM and internal EEPROM but the fact that it appears to be able to keep the WiFi connection up while only consuming 24uA, and have a fast wake-up from a 5uA deep sleep would be very useful. Is anyone currently working on this?

@seonr aka Unexpected Maker is making a ESP32-S2 ProS2 dev board. That's the hardware side covered. Not sure about software side.

Espressif is planning on using TinyUSB in the ESP-IDF for the -S2 ( so adding basic support should be easier in MicroPython (which uses TinyUSB for SAMD and nRF) and CircuitPython (which uses TinyUSB for most ports.)
