Adafruit NeoPXL8 FeatherWing for Feather M4 Board handles all the NeoPixeling and supports up to 8 strands of concurrent DMA output. Each output can be 1750 RGB pixels long for 14000 pixels. The Adafruit NeoPXL8 FeatherWing, combined with DMA and SAMD51’s fast 120MHz processor, helps to manage the animations for hundreds of pixels easily. This FeatherWing does the level-shifting and pin arrangements for the users to make connections easy. All the 8-strands have a level shifter that converts the 3.3V logic level to 5V. The integrated little switch-cap converter generates a 5V power supply for the users, and the inline 100Ω resistor after the buffer reduces ringing on long-wiring runs.
Users can choose the wiring option and solder in the preferred connectors to keep the Wing compact. The NeoPixels can be powered using terminal blocks or bus bars to connect all the ground/5V power wires and power from a 5V supply.
