+5V
NeoPixel matrix power input. Adafruit product page says to use a 5V supply for the flexible 8x32 NeoPixel matrix; NeoPixel Uberguide identifies +5V as one of the three NeoPixel inputs.
Type · PowerVoltage · 5V typical NeoPixel supply; product page warns current can exceed 15A at full white and recommends keeping draw under 5A.
GND
Ground return for matrix power and shared microcontroller reference. NeoPixel Uberguide says the three inputs are +5V, ground, and data, with GND shared between the supply and controller.
Type · GroundVoltage · 0V reference
DINDI
NeoPixel data input at the input end of the matrix. The Uberguide identifies DIN or DI as data input and says NeoPixel data moves in the indicated direction.
Type · Signal
DOUTDO
Optional NeoPixel data output at the end of the chain for adding more pixels. The Uberguide says DOUT or DO can be left unconnected if not chaining.
