Bill of Materials

Core electronics (ESP32, DFPlayer Mini, resistors, capacitor, connectors, speaker) are identical across every gate model — the motorized variant just adds a few parts on top of that same base. Only the LED strip quantities and 3D printed parts otherwise change — see each page for the details.

PCB Compatibility

Four boards exist today — see the Downloads page for Gerber files and full descriptions. This is which gate model can use which one.

Gate model	PCB V1 3 LED outputs	PCB V2 1 LED output	PCB V3 1 output + AC/DC jack	SG-1 Motorized PCB 12V, NEMA17 driver
Pegasus / SG-1 (Basic) / Tollan / Orlin 15cm gates	✓	✓	✓	⚠ works, not recommended
SG-1 (Motorized) / Universe 15cm gates	✗	✗	✗	✓ required
Pegasus Medium ~30cm — coming soon, 3D model not yet published	✓	✓*	✓*	⚠ works, not recommended

⚠ Using the Motorized PCB on a static 15cm gate (no actual motor installed) technically works — it carries the same base circuit as V1/V2/V3 — but it's built around 12V input rather than USB-C, so you'd need a 12V power supply and would be paying for a driver and buck converter you never use. More parts, more assembly, no upside over just building on V1/V2/V3 — not recommended unless you already have the board on hand.

Running a single LED strip on a PCB V1 board (instead of the three it's wired for): plug that one strip into the chevron output — that's the pin the single-strip firmware build actually drives.

Either way, the choice between the single LED strip and multiple LED strips firmware build is made on the Flash a Gate page when you flash — both behave identically in practice, it's purely about matching whichever way you wired the LEDs.

* Pegasus Medium's 3D model works equally well built for a single strip or three separate strips — it's a real choice, not just a fallback. Build it for one strip and any of V1/V2/V3 works (V1's LED output wired to the chevron connector, same as above). Build it for three separate strips and only PCB V1 can drive it — V2/V3 physically have just the one LED output, they can't feed three strips no matter the firmware.

📝 Notes

A future gate model V2 is planned, built exclusively around a single LED strip and a 5mm COB LED strip instead of the WS2812B 10mm strips most current models use.
That 5mm COB strip is already usable today on any current (V1) gate model — nothing about it is specific to the future V2 design.
Recent firmware accepts any LED density on the glyph ring. If the LEDs don't land perfectly on each glyph once assembled, the advanced calibration mode lets you manually assign each LED to a glyph by hand — no need to panic if the spacing isn't exact.
Gates are, in theory, printable at any size — the only real requirement is that LEDs land roughly at the chevrons and glyphs. Default sizes are tuned so a 96 LED/m strip lines up almost perfectly, but an imperfect alignment still gives good results.
