NEW PRODUCT – Adafruit Pixel Shifter – For Addressable LEDs
We’ve been stocking WS2811-n-friends for a very long time, sufficient to see many iterations and variations of the “one-wire-control” addressable LED pixel. We name them NeoPixels, for the reason that half quantity itself can change fairly a bit, however all have the identical thought: ship shade knowledge to lights and so they’ll change on their very own with out having to continually PWM three or 4 diodes. Regardless of this simplicity, we’ve seen of us battle with them due to voltage degree expectations: some NeoPixel-compatible pixels are very choosy and wish 5V logic degree. With out the proper voltage, you get flickering or bizarre habits. There’s additionally some funky variants just like the TM1814 that need inverted sign ranges.
To make wiring simple, so that you don’t want a separate chip or breadboard, we made this Adafruit Pixel Shifter which will be simply wired in-line to your LED strips or grids or some other form configuration they arrive in. On-board is a tiny 5V voltage generator, two shifters and one inverter. Present it 3-5V energy (it solely wants a couple of milliamps) and it’ll shift as much as two sign strains, with considered one of them additionally obtainable as an inverted output. All pins can be found on 0.1″ terminal blocks, use a small flathead screw to connect your strong or stranded core wire, 18AWG to 26AWG.
It’s a easy, low-cost, and solder-free method to make your finicky LED setups work with 3.3V logic chips just like the RP2040, ESP32 / ESP8266, STM32, SAMD, Raspberry Pi or different fashionable 3.3V-logic gadgets. You may also use it for different 5V-logic-needing IC’s that require one or two inputs. The onboard 74HCT2G34 shifter can simply deal with 10MHz indicators, most LED strips use a sign frequency of about 800KHz. An ideal companion to WLED!
You may also use this board as a fast sign debugger: there’s a single tiny NeoPixel on the Information line, so you’ll be able to confirm that you just’re getting legitimate sign on that pin. When you aren’t utilizing NeoPixel protocol, or wish to maintain it darkish, disable it by chopping the hint on the again.
