@op8 sorry for the late reply, thank you very much, i still love it to watch the price on it. The M5 core is the regular black framed M5-core and the bottom is the M5GO/FIRE Battery Bottom Charging Base SKU:A014 from this M5-Stack-Shop (do not forget to buy the chargning base plate as i did, these are 2 seperate items to buy) It has the rgb-led strip built-in but it is only barely used in my code.. My Intention was to show major price movements with red/green flashing lights (and sounds) for example. Unfortunately i did not implement more functions since then.
A little problem i have experienced is the wake-up behavour on usb-cable because with the battery base it behaves different as it is with standart battery back. But this can be solved in the code if you change the settings at //Power Settings

Works with GxEPD library using GxGDEW0213Z16 display type.
Not GxEPD2 :-(

By now you know this repository is crap. This is what worked for me on a 1.54 e-ink display. It should work on other sizes as well.
NOTE: This display requires 3.3 data lines. It works on 5v data lines, but just barely. The display is not crisp. I've read it's possible to use a 10k/4k7 resistor divider for 5v data lines, but it didn't work for me.
Download this library https://github.com/ZinggJM/GxEPD
From Arduino IDE, open the example
Select this display
#include <GxGDEH0154D67/GxGDEH0154D67.h> // 1.54" b/w
Use these pins
GxIO_Class io(SPI, /CS=/ 10, /DC=/ 9, /RST=/ 8);
GxEPD_Class display(io, /RST=/ 8, /BUSY=/ 7);
Connect as follows (display / arduino):
VCC / VCC
GND / GND
D/C / D9
SDI / D11
CS / D10
CLK / D13
BUSY / D7
