The special thing about the board is that all the required socket pins can be soldered from the top side. The laborious and error-prone soldering of socket pins from the bottom side is no longer necessary.
Note: When soldering the pin headers make sure that the pins of the socket pins only protrude very slightly from the holes in the board, so that the SRAM IC above can be placed flat on the board.
