The SX4 series are a socket compliant to "8Byte DIMM" standardized
at JEDEC.
2. JEDEC Standard MO-161
The applicable module board 1.27mm pitch 168 pos. for double-sided
connection.
3. Easy PC Board Pattern Design
The lead length for soldering dip connection on the board is 1.27mm,
row-row 1.27mm, 1.6mm, 1.905mm, and staggered alignment in 4
rows.
4. Compatible with 5V and 3.3V Operating Voltage Module
Board
5. Prevents Mis-insertion in Module Board
The key mechanism prevents mis-insertion in the module board.
6. Prevents Displacement of Module Board
The structure to sustain the module board on both sides prevents
displacement of the module board.
