About the Pixfrog satellite PCB

Pixfrog satellite is an open source PCB design by Lefix2, published on GitHub under the MIT license. It is a 2-layer board measuring 39.9 × 31.5 mm, with 20 components from 14 distinct parts.

Other key parts include the 74LVC2G17 and LD1117S50TR_SOT223. By type, the board carries 6 resistors, 5 connectors, 4 diodes, 3 capacitors and 2 ICs.

It belongs with the rf & radio and displays & leds designs in this gallery.

From the project

Professional Art-Net pixel controller and dmx node — eight parallel channels, configured locally

The board half of pixfrogsatellite; its mechanical design (enclosure) is WIP** — the board mounts bare for now, H1/H2 tying its GND to the chassis or heatsink that carries it.

KiCad 10 project for the remote node that sits at the far end of a long LED cable run. The controller (or pixfrogshield) sends one channel's two signal lines down the cable; over distance the edges degrade and the strip voltage sags. The satellite re-squares the signal with a Schmitt-trigger buffer and injects local strip power**, so the LEDs see clean data and full voltage regardless of run length.
