	\|faq=; ~~Why~~ is the ~~screen all white~~?		\|faq==== <span style="color: rgb(52, 176, 176);">Q1: The display shows nothing at all after connection. What should I do?</span> ===
	: ~~Check reset~~, ~~chip select~~, ~~data/command~~ pins, and ~~initialization model~~.		A1: First check the FFC ribbon orientation — the gold fingers must face up when inserted into the FPC connector; a reversed ribbon will keep the display from lighting up. Also make sure the locking cap is pressed down firmly. If the ribbon is fine, the most likely cause is an I2C address mismatch: the address differs between displays (commonly 0x78). Try a different address in your sketch, and check whether SDA/SCL are swapped.
	; ~~What if the image has noise~~?
	: ~~Lower~~ the ~~SPI clock~~ and ~~shorten the connection wires~~.		=== <span style="color: rgb(52, 176, 176);">Q2: Can this shield be stacked together with other shields? Does it take up too many pins?</span> ===
			A2: Yes. The shield actually uses only 4 pins (3V3, GND, SDA, SCL); all other pins are left unconnected (NC) on the board, so the remaining pins of the main board stay available and other shields are unaffected. The only thing to watch: if other devices share the I2C bus, avoid address conflicts.

			=== <span style="color: rgb(52, 176, 176);">Q3: If I switch to a different main board or a different OLED display, do I need to replace this adapter shield too?</span> ===
			A3: No. The Arduino interface is a universal standard — any main board with standard Arduino headers (UNO, Mega and all kinds of compatible boards) stacks directly. On the display side, any OLED with an FPC 30P interface and I2C protocol (common drivers: SSD1306, SH1106, etc.) can be attached, regardless of size or resolution. One adapter shield serves many board and display combinations.
