Doubt about Micropython firmware for M5 Fire
I just received my Fire and is awesome but I am not sure about which firmware I should flash to use Micropython.
For now I tried the v0.4.0 here https://github.com/m5stack/M5Cloud/tree/master/firmwares and it works fine but I see that there is another version here as well https://github.com/m5stack/M5GO/tree/master/firmware/v0.16-psram
There is also another firmware here https://github.com/m5stack/M5Stack_MicroPython/tree/m5stack/MicroPython_BUILD/firmware/esp32_psram
Which one is the most recent and which should I use?
