Using this expansion connector you have access to McBSP1, McBSP3, I2C2, MMC2(8 bits), nReset and REGEN signals from OMAP Processor. The interface is at 1.8V on all signals. Only 1.8V CMOS levels are supported. DO NOT expose the header to 3.3V.<br>J990 connector is [http://beagleboard.org/ BeagleBoard] compatible expansion connector.<br>IGEPv2-NOWIFI board is fully compatible. Other IGEPv2 board versions need software configuration to disable wifi interface and others because of shared hardware lines.<br>MMC2 interface is used by wifi module.<br>McBSP3 interface is used by PCM TPS65950 interface.<br>
See which versions have WIFI/BT combo is [[Frequently Asked Questions and Their Answers#Which_revision_is_my_IGEPv2_board.3F|available]].

=== J960 connector ===
This connector is used mainly to connect via serie to IGEP Software using [http://en.wikipedia.org/wiki/RS-232 RS232 standard].
On IGEPv2 revision B:
*This J960 connector has only Debug RS232 interface
*So, it is needed null modem configuration (direct connection between two computers). RX and TX lines are crossed in this null modem configuration between two equipments (TX1->RX2 / TX2->RX1).
On IGEPv2 revision C:
*You should modify your serial debug cable in order not to damage your serial PC port. *Additional RS232 port (UART1) on same J960 connector. It is only needed to rotate 180o the IDC-10 (AT-Everex) to DB9 cable.*It has been added resistors for alternative UART1, UART2 and UART3 hardware selection.
*See [[How to use UARTs#RS232_Schematic_Igep_V2|Schematics]] (RC) for more information.

=== J970 connector ===
J970 is used to implement a keypad, it is connected to TPS65950. The keypad interface controller provides an enhanced keypad decode capability and simultaneously reduces host processor software overhead. When a key button of the keyboard matrix is pressed the corresponding row and column lines are shorted together. To allow key press detection, all input pins (KBR) are pulled up to VCC and all output pins (KBC) driven to a low level.<br>Any action on a button generates an interrupt to the sequencer.<br>The decoding sequence is written to allow detection of simultaneous press actions on several key buttons.
More information in [http://www.ti.com/product/tps65950 TPS65950] datasheets. TPS65950 send via I2C1 all the interrupt request. <br>
