{"product_id":"emu-led-button-pcb","title":"EMU LED Button PCB","description":"\u003cp\u003eThis PCB goes behind the eject button on each EMU lane. Four RGBW LEDs light the button up, so Happy Hare can show load and unload animations, and an SMD switch gives a crisper click than the D2F switch with magnets. It also cuts down the wiring and soldering in the button.\u003c\/p\u003e\u003ch3\u003eWhat it replaces\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1 NeoPixel, 1 D2F-L switch and 4 of the 6×3 mm magnets from the base EMU BOM, per lane\u003c\/li\u003e\n\u003cli\u003eThe JST-XH 5-pin header is already soldered on\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eGood to know\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOne PCB per lane.\u003c\/li\u003e\n\u003cli\u003eIn Klipper, set \u003ccode\u003echain_count: 5\u003c\/code\u003e per lane: LEDs 1–4 are the button (exit LEDs), LED 5 is the dry box (entry LED).\u003c\/li\u003e\n\u003cli\u003eThe eject button pin gets a \u003ccode\u003e!\u003c\/code\u003e (\u003ccode\u003e^!mmu0:EJECT_BUTTON\u003c\/code\u003e), unlike the D2F setup.\u003c\/li\u003e\n\u003cli\u003eRun a 600 mm AWG26–28 wire from DOut to the LED IN of the dry box, then you can leave out the third WAGO.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIn stock in the Netherlands\u003c\/strong\u003e, ships in 1–2 working days with no import fees.\u003c\/p\u003e\u003cp\u003eFor the EMU by DW-Tas and igiannakas.
