Option 1: epaper display 3.7 inch
Required parts:
- Waveshare 18381 3.7inch e-Paper Display + Waveshare Universal e-Paper Raw Panel Driver HAT 13512.
- Alternatively Waveshare 18057 3.7inch e-Paper HAT
Wiring of the Epaper 3.7 inch display
Please make sure to switch the "Display Config" switch to A. "Interface Config" is to be switched to 0 (4-line SPI). (Alternatively Waveshare 18057 3.7inch e-Paper HAT

If you are using the hat 13512 please make sure to switch the "Display Config" switch to A. "Interface Config" is to be switched to 0 (4-line SPI).
Important remark for e-Paper Driver Hat Waveshare 13512 Rev. 2.3: Waveshare introduced a 9-cable connection since Rev. 2.3. The additional cable PWR (red) needs to be connected to 3.3 V. So connect it to PIN#1 on the Raspberry GPIO.
Remark: If you have a barometric sensor or ahrs connected you may have conflict with GPIO Pin 11. You can also use PIN 16 (GPIO 23) for the RST line. To do that please modify in /home/pi/stratux-radar-display/main/displays/Epaper_3in7/epdconfig.py line 38/39:
# RST_PIN = 17 # if directly as hat
RST_PIN = 23 # for cable mounted in stratux on different GPIO 23, which is PIN 16
Option 2: epaper display 1.54 inch
Required parts:
- Waveshare 12955 1.54inch epaper Display
- Alternatively Waveshare 12561 + waveshare hat 13512.
