Suggestions for future releases.

Where can we get a device for building prototype?
-
I agree, the bundled library for the screen graphics works but it would be nice to me able to change it out without having to edit the m5stack library itself.
-
Also I can't seem to figure out how to power it off while its charging...
-
All very cool, but if its real it will be better if main core and bottom will have 4 M3 screws instead of 2, becouse main and bottom cores not fully close together.

Hey @tonywestonuk. I tried using the TFT_eSPI library that you mentioned (I'm having issues with nRf24L01 and LCD working together). When you specified the pins for CS/CE did you use the "D8" node-mcu type pin names or just "27"? If so I wouldn't mind knowing what values (I know which GPIO pins I should be using).
Cheers!

Ah, I think I might have been a bit blind this morning and didn't spot this:
I'm guessing that there isn't any more modifications that you had to make to get it working?

The Grove's Vcc would be nice to be 3.3V as the ESP32 is powered by 3.3V. Also, the Grove socket/connector is too tight, so much so, Grove male connector will break the edge.
-
but many devices need 5V, ESP32's IO can fit for 5V, anyway, i will think about this.

M5Stack now uses SPI mode for SD Card access.
It would be better if in some future core board release 1-line SD mode could be used.
Not only it works better, but one extra pin would be available to the user (only 3 pins are needed for 1-line SD mode).
If psRAM is used (hopefully all new M5Stacks will be with psRAM), this pin could be routed to the M5Stack 2x15 pin header instead of unusable GPIO16/GPIO17.
I know it would require rearanging the pins for some peripherals, but I think it's worth the effort. -
thanks for suggestions
