Note: When soldering the pin headers, make sure that the pins of the socket pins only protrude very slightly from the holes of the board, so that you can lay the SRAM IC above flat on the board.
The special feature of the board is the fact that all required socket pins can be soldered from above. The tedious and error-prone soldering work of having to solder socket pins from below is no longer necessary.
