The current available on the DC_5V rail is limited to the available current that remains from the DC supply that is connected to the DC power jack on the board. Keep in mind that some of that power is needed by the USB Host power rail and if more power is needed for the expansion board, the main DC power supply current capability may need to be increased. All signals are 1.8V except the DVI_PUP which is a 3.3V signal. The 1.8V rail is for level translation only and should not be used to power circuitry on the board.

IGEP0020 expansion connectors

Igepv2 rc photo2.jpg


J990 connector

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.

J990 connector is BeagleBoard compatible expansion connector. IGEPv2-NOWIFI board is fully compatible. Other IGEPv2 board versions need software configuration to disable wifi interface and others because of shared hardware lines. MMC2 interface is used by wifi module. McBSP3 interface is used by PCM TPS65950 interface.

See which versions have WIFI/BT combo available.

J960 connector

This connector is used mainly to connect via serie to IGEP Software using 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 Schematics (RC) for more information.

J940 connector

This connector is used mainly to connect via RS485 (UART1) with other devices. User can use this connector to power the board with 5VDC. Use only 5V regulated DC. The IGEPv2 BOARD does not use this 9v power supply. Only on IGEPv2 revision B, the PWR_9V input is directly routed to JC01 and J971 connectors. On IGEPv2 revision C is not available.

J400 connector

J400 is used to JTAG (Joint Test Action Group). JTAG is a standardized serial protocol widely used in printed circuit boards. Its main functions are:

  • Debug the software of an embedded system directly
  • Storing firmware
  • Boundary scan testing

JTAG Suggested:

  • JTAG Debugger XDS510+ USB from Spectrum Digital with Code Composer Studio 3.3 or higher.
  • JTAG Debugger XD100v2 USB from Spectrum Digital with Code Composer Studio 4 or higher.

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. Any action on a button generates an interrupt to the sequencer. The decoding sequence is written to allow detection of simultaneous press actions on several key buttons.

More information in TPS65950 datasheets. TPS65950 send via I2C1 all the interrupt request.

  • Can handle up to 8 x 8 keypads, IGEPv2 can handle up to 4 x 4 keypads.
  • Optionally, you can decode via Omap software.
  • Event detection on key press and key release.
  • Multikey press detection, can detect up 2  keys at the same time.
  • Long-key detection on prolonged key press.
  • Programmable time-out on permanent key press or after keypad release.

JA42 connector

JA42 is used for DVI (Digital Video Interface) control part, TouchScreen control and SPI1.

The current available on the DC_5V rail is limited to the available current that remains from the DC supply that is connected to the DC power jack on the board. Keep in mind that some of that power is needed by the USB Host power rail and if more power is needed for the expansion board, the main DC power supply current capability may need to be increased. All signals are 1.8V except the DVI_PUP which is a 3.3V signal. The 1.8V rail is for level translation only and should not be used to power circuitry on the board. The 3.3V rail also has limited capacity on the power as well. It is suggested that the 5V rail be used to generate the required voltages for an adapter card.


  • Note that only IGEPv2 RG version has all 22 pads available. Other boards have only first 20 pads available.
