Top quality, great display
Great display, after some hours of struggling (I'm a beginner) I managed to drive this display with my NodeMCU microcontroller, from Arduino IDE, using the u8g2 graphics library. Amazing, it's using the fast mode (hardware SPI), with 3 wires only (4 is optional) + GND + 3v3.

You can see the library's example here, doing a demo:

Amazing little display and very nice, refined screen. Top quality.
Please Audiophonics, keep this on stock, a lot of them, as long as you can. Really easy to work with.

Highly recommended.

My review on the White SPI display
Nice display, once I got it to work. if you use this display with an RPI4 equipped with Volumio or Roon or LMS it is probably a breeze to get it to work. Plug and play. One thing to look out for is the 16 pins flatcable connector that can be fitted in two ways on the display. The cable keying (triangle indicating pin 1 on the connector) should be connected to pin 15 of the display. something to look out for.

I tested the display using the python luma driver with the following test code:
from luma.core.interface.serial import spi
from luma.core.render import canvas
from luma.oled.device import ssd1306, ssd1322,ssd1325, sh1106
from time import sleep
import RPi.GPIO as GPIO

serial = spi(device=0,port=0,gpio_DC=27,gpio_RST=24)
device = ssd1322(serial, rotate=0)

# Box and text rendered in portrait mode
with canvas(device) as draw:
draw.rectangle(device.bounding_box, outline="white", fill="black")
draw.text((10, 10), "Hello World", fill="white")
sleep(10)

The GPIO pins mentioned in the code above were determined after measuring the pins from CN4 all the way to the Pi pins.

An improvement would be to add a column to the display specs on the website indicating what PI pins are used. Now I had to measure them myselve.
