LED Strip Compatibility

PicoLume receivers work with 5V, 12V, and 24V addressable LED strips using the WS2812B protocol.

POPULAR WS2812B

The standard "NeoPixel" - widely available, affordable, good color accuracy. 60 LEDs/m is common for props.

RGBW SK6812

Drop-in WS2812B replacement. Available in RGBW variants for better white output.

12V/24V WS2811

External driver chip - often used in bullet-style pixels for larger installations.

SMOOTH COB LED Strips

Chip-on-board strips with WS2812B protocol. Smooth light output without visible dots.

Power Planning

WS2812B LEDs draw up to 60mA per LED at full white. For a 60-LED strip, budget ~3.6A at 5V. Use adequate wire gauge and consider power injection for longer runs.

PCB Design Series

Our hardware designs are organized into series, each targeting different use cases.

PRIMARY

series-prop

The main production design. Contains the PicoLume Board - a compact receiver control board with RP2040, RFM69HCW radio, USB-C, and LED driver circuitry.

PROTOTYPE

series-legacy

Early prototype designs (v1-v4) used for proof-of-concept testing. Not recommended for production use.

Alpha stage

Hardware designs may change as we refine the system.
