Your display uses SPI with a single bidirectional data pin called SDA.
Most libraries treat the SDA pin as write-only. They make no attempt to use it for reading.
AVR hardware and Atmel ARM hardware is not capable of "bidirectional pin"
From your photo, U4 looks like 3.3V regulator chip but it might be a transistor for switching the backlight.
What are the values of R1, R5, R6 ?
I suspect that you can connect VCC pin to 5V (if U4 is a LDO regulator)
If U4 is a transistor, it is safer to connect VCC to 3.3V
I suspect that the signals must have 3.3V logic e.g. with Zero, Due, STM32, ...
I have never seen this board in real life.
Only an owner can identify U4, R1, R5, R6.
