+    :param ~microcontroller.Pin pin: The pin to output neopixel data on.
+    :param int n: The number of neopixels in the chain
+    :param int bpp: Bytes per pixel. 3 for RGB and 4 for RGBW pixels.
+    :param float brightness: Brightness of the pixels between 0.0 and 1.0 where 1.0 is full

+    :param bool auto_write: True if the neopixels should immediately change when set. If False,

+    Example for Circuit Playground Express:

+
+        import neopixel
+        from board import *
+
+        RED = 0x100000 # (0x10, 0, 0) also works

+    Example for Circuit Playground Express setting every other pixel red using a slice:
+
+    .. code-block:: python
+
+        import neopixel
+        from board import *

+
+    .. py:method:: NeoPixel.show()
+
+        Shows the new colors on the pixels themselves if they haven't already
+        been autowritten.
+
+        The colors may or may not be showing after this function returns because
+        it may be done asynchronously.
+
+    .. py:method:: NeoPixel.fill(color)
+
