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.
Hint: When soldering the pin headers, care should be taken to ensure that the pins of the socket pins protrude only slightly from the holes in the board, so that the round contact surfaces below do not touch the IC legs of the ICS525.
