It would be very helpful to know what the model of the display is. I have been trying to set up one of these in ESPHome using the ssd1306 module but it's not working. I'm not sure if that is what this is using.

Change pins SSD1306Wire display(0x3c, SDA, SCL); to SSD1306Wire display(0x3c, SCL, SDA); That board have some mistakes.

For example: if You move joystick Right it will Reset. 8-)
