1. Waveshare 7.5" crashes and reboots Raspberry Pi zero when plugged on the HAT · Issue #92 · waveshare/e-Paper · GitHub

   I've actually just received one of these HATs (the crashing version), and found this issue because my Pi Zero was crashing. Thanks for all the suggestions here.
   Instead of messing around with capacitors, wouldn't it be simpler to do this:
   
   remove (clip off / unsolder) the 5V pin(s) from the Pi header
   attach the HAT to the Pi
   solder a wire from the 3.3v pin to VCC on the HAT

3. Anyone got this thing working? (2.13in e-ink display) : esp8266

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

8. To everyone having issues · Issue #11 · HelTecAutomation/e-ink · GitHub

   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
