LED indicator for MMU2S/MMU3 ir sensor

Aktualizacja u źródła: 25 wrz 2023

Informacje o modelu

I needed a led indicator, like what zzjlamb did : https://www.printables.com/fr/model/104680-mmu2s-ir-sensor-status-indicator
But for the Easy IR Sensor calibration system from Peter Larsen :
https://www.printables.com/fr/model/7789-mmu2s-easy-ir-sensor-calibration

We ordered some pcb made for this special need (from Seeed Studio, China) and here it is:
It works like a charm, without any modification on Prusa electronics or wires.

The BOM :

1 x 555 Timer
1 x 10 KOhm 1/4 W resistor
1 x 1 KOhm 1/4 W resistor
1 x 5mm Blue LED
1 x PCB - 20 mm x 10 mm

Feel free to use it for your own :-)

I can also sell the soldered PCB, ready to use for 14€. Contact me if needed.

EDIT 01/06/2023 : Gerber files added

EDIT 25/09/2023 : New design with front oriented led. old version is V5, new one is V6
