Adafruit NeoRGB Stemma - NeoPixel to RGB PWM LEDs and Strips

The Adafruit NeoRGB Stemma board simplifies wiring for true analog RGB LED strips and LEDs which require 12V DC and driver FETs. This plug-and-play STEMMA board features a 2mm JST PH connector on one end and a 5-pin 0.1" screw terminal block on the other, converting standard 3-5V 800KHz NeoPixel signals using a WS2811F chip to high-efficiency AO3406 N-channel FETs capable of sinking 3 Amps per channel with 50milliOhm Ron.

Key benefits include controlling any PWM-able common-anode RGB LED strip or LED as a single NeoPixel at up to 16V and 3 Amps per channel, suitable for large analog LEDs or arrays, and LED strips, including 3 independent single-channel strips. Note the WS2811 chips do not support 4 channels, so RGBW strips are unsupported.

Usage involves connecting a 2mm JST PH cable signal wire (white) to a NeoPixel-compatible 3 or 5V logic signal, powering the LED strip with 3-16V DC through the red wire or terminal block depending on current draw, and establishing proper ground connections.

The onboard green LED indicates power status, and a red signal LED blinks when data is transmitted. The board supports signal chaining with an output pin.
