The pixel
Main characteristics:
- 12.5mm diameter
- 2.5mm total thickness
- 800 KHz speed protocol
- Chainable design, meaning that you can connect several of these to one pin and chain them
- 5-9VDC power (can run at 3.5V but color will be dimmed), constant current 18.5mA per LED (~55mA max total per pixel)
Hooking up a NeoPixel
A NeoPixel must be connected with three wires to a FLORA-type board. Depending on the board, the wiring is bit different. E.g. on a GEMMA, the signal must be wired from A1.
