"With our newly developed Adafruit NeoRGB Stemma board, wrangling with 'true analog' LED strips containing 1-3 channels of RGB or White LEDs will now be effortless. This innovative solution streamlines the wiring process by providing 12VDC and driver FETs, making it a game-changer for both industry professionals and customers alike."
The NeoRGB is a convenient, no-soldering STEMMA board that features a 2mm JST PH connector on one end and a 5-pin 0.1" screw terminal block on the other. It efficiently converts standard 800KHz NeoPixel signals using a WS2811F chip to AO3406 N-channel FETs, which can handle a significant amount of current at 3 Amps per piece and boast a low 50milliOhm Ron.
This feature allows for the use of any PWM-able common-anode RGB LED strip or LED as a single NeoPixel, with a maximum voltage of 16V and 3 Amps per channel. This is ideal for controlling large analog LEDs or arrays, as well as LED strips, including non-RGB options. It even supports the control of 3 independent single-channel LEDs or strips. Please note that the WS2811 bare chips do not have the capability to support 4 channels, making it unsuitable for use with RGBW strips.
Usage is easy. First you'll need a 2mm JST PH cable, such as this one with pins. Then pick one of two powering options
If you are using less than 2A of current total across all 3 channels:
- Connect the white wire to your NeoPixel-compatible signal, 3 or 5V logic.
- Connect the red wire to 3-16VDC, this will power the LED strip
- Connect the black ground wire to your microcontroller and power supply shared ground
If you are using more than 2A of current total across all 3 channels, you'll need to wire the power supply to the terminal block since JST PH connectors are only rated for 2A.
- Connect the white wire to your NeoPixel-compatible signal, 3 or 5V logic.
- Connect your 3-16V power supply positive pin to the V+ to the terminal block, keep the red wire from being used by taping it or cutting it off.
- Connect the 3-16V power supply ground pin to the GND on the terminal block
- Connect the black wire as a 'reference' ground to your microcontroller that is providing the NeoPixel signal
An onboard green ON LED will let you know that it is powered correctly, and a red Signal LED will lightly blink when data is sent on the Signal line. If you need to chain more than one, or want to connect some other NeoPixels to the output, there's a pin for the Output signal on the board.
