The 41AB050-2M is a replacement logic board for LiftMaster and Chamberlain AC belt drive openers from 2005 to 2015. 315MHz Security+ receiver with a purple learn button and a light socket. Comes with the end panel too. If your belt drive opener stopped responding to remotes or the board's acting erratic after a power spike, this is the board you need. Confirm it's an AC belt drive model, not chain drive or DC, and that it's from that 2005-2015 production window before ordering.
