Circuit Board Appraisal

Chamberlain LiftMaster Garage Door Opener Logic Board Assembly

The item is a black, rectangular electronic component, likely a logic board or control unit for a garage door opener, housed within a robust plastic casing. It is presented in its original cardboard packaging, which is partially visible. The visible parts of the casing show two distinct sections with labels and control elements. The upper section features a black sticker with safety warnings and manufacturing information, including 'DANGER • PELIGRO • AVERTISSEMENT', FCC compliance details, and a 'PART NO.' field, though the specific number is not clearly legible. There are pictogram warnings related to electrical hazards and moving parts. The lower section of the unit has multiple white printed instructions and settings, along with several control buttons: two blue circular buttons, an orange square button, and a black circular button that appears to be a 'learn' or 'program' button. A small green digital display is also visible. A white wire, possibly an antenna, is connected and extends from the unit. The packaging itself, labeled 'Lift Plus' and 'Ideal for Heavy-Use Applications', suggests it is associated with a screw-drive mechanism, indicating heavy-duty use. Another label mentions 'De Sola Frecuencia 390 MHz', identifying the operating frequency. The overall condition appears to be new or unused, as it is still in its packaging, with bubble wrap cushioning visible around the unit. The cardboard box shows some minor wear from handling. The item is designed for residential or light commercial garage door systems, aimed at durability and reliable operation.
