SOM240_1 Connector Pinout

The SOM240_1 connector provides access to two MIO banks (MIO501, MIO502), HPIO bank 66 (HPA), HDIO bank 45 (HDA), and the PS-GTR transceivers (MIO505). It also provides sideband signals for configuration and operation of the board. For additional pin definitions see the K26 SOM XDC file.
