From the project
KiCad design for the Matter Over Thread Door Sensor project.
KiCad design for the Matter Over Thread Door Sensor project.
A door sensor PCB that uses the MS88SF2 Radio-module (Nordic nRF52840) to detect door open/close events via a reed switch and send them over a Thread network using the Matter protocol.
- Size: 40 × 30 mm - Layers: 4 (F.Cu signal, In1.Cu GND plane, In2.Cu power plane, B.Cu signal) - Thickness: 1.6 mm - Version: HW v1.0
