The Intel® Edison Compute Module interfaces with end-user systems via a Hirose* 70-pin DF40 Series header connector. The table lists the varying heights of receptacle connectors to consider when designing a custom expansion board.

Hirose header connector DF40C-70DP-0.4V(51)

This image shows the Hirose header connector DF40C-70DP-0.4V(51), used in the Intel Edison Compute Module. The expansion board should have a Hirose 70-pin DF40 Series receptacle connector.

  • The image shows a shield height of 1.5 mm and sits flush against the connecting PCB if a 1.5 mm stacking height receptacle connector is used.
  • The receptacle connector recommended is the DF40C(2.0)-70DS-0.4V(51)which has a 2.0 mm stacking height.
  • This receptacle connector is the one used in the Intel® Edison Arduino Expansion Board and the Intel® Edison Mini-Breakout Expansion Board.

Different receptacle connectors mate with the header connector. The stacking height is an important detail to consider when designing a custom expansion board.
