ESP32 w/4mb, and a SparkFun ESP32 with 16mb
of RAM or flash ?
https://www.sparkfun.com/products/15663
The sparkFun says 16MB Flash and 520k internal SRAM.

And the other one shows 4MB (I'm assuming flash, but it's cheap generic one, so not completely sure)

So there is no SPIRAM/PSRAM -> MicroPython shows 70-100 kB of free SRAM.
My "MicroPython Samples". My "MicroPython Firmwares" with many options (double precision, ulab, etc).

Ah, ok. Thanks - that makes sense now.
