When installing a DiskOnChip module onto your board, please take note of the following:
1.Orient yourself properly with the location of the DiskOnChip socket. Try to locate the pin 1 location on your socket. Pin numbers are usually printed on either the component side or the solder side of your board.
2.Locate the Pin 1 location on your DiskOnChip module. More often than not, Pin 1 can be found on the lower right corner of the chip. Please refer to the diagram for the exact location.
3.Once you have figured out where the pin 1 locations are (on both chip and socket), align the module’s pins on an upright angle against the socket. Using both thumbs, gently press the module into the socket until all the pins are secured to their designations.
