@soloam said in Roller Shutter Node: I'm having difficult finding the IC4 ACS712_5A, if I search for "ACS712 5A" I only get the assembled unit. Can I get one of this and unsolder the IC and use it? weird because it's easy to find on aliexpress/ebay like berkso said, or unsolder it it's easy. you can also find it on arrow, digikey. for rollershutter mode, no need of very precise data, as it's used as a "switch" sensor, and my sketch, adc sampling/basic filtering etc are using state machine if i remember well, so nothing blocking. there is also available footprints for filtering if needed. but if you don't have any Ic, you still can use the board, just take a look at the defines in sketch and proceed a manual calibration. enjoy
