4.5 LVDS port connector
The single channel LVDS display port can be direct connected to a LVDS 18 bit display.
The VLCD voltage is 3.3V and switched on the baseboard. The current limit is 1.2 A.
Connector is a JAE FI-S25P-HFE. Matching connector on display cable is a crimp connector
FI-S25S housing and a cable with FI-C3-A1-15000 crimp contacts.
This connector is used because a wide range of displays does have a JAE FI-S series con-
nector (with different pinouts) and it's easy to handle identical crimp contacts for the cable
manufacturer.

On default a 9 pin connector is mounted on pin 53..61 to use a COM port standard adapter
cable. Italic signals do have a 4k7 pull-up on the module.
!!! Pin 14 has a pull-down due to bug in processor revision. Will be changed to pull-up when
bug in processor is fixed.!!!

to DSUB9 adapter cable for debug output of bootloader and kernel with TX, RX, RTS and
CTS to a terminal.
Pin 1 of this adapter should connect on pin 53 of the 66 pin connector. Pin 62 is the key pin
and should be removed.
On pin 36 & 38 is a second RS232 COM port (RXD2/TXD2).
4.12.3 TTL COM port
There is additional serial port with 3.3V TTL level (RXD1/TXD1).

3.3V compliant and have 4.7k pull-ups on module.
4.12.5 I2C
The module supports a I2C interface as I2C master. Signals are 3.3V compliant and have
4.7k pull-ups on module.
4.12.6 ADC In
4 ADC inputs (ADC_IN0..3)
Resolution: 12-bit

4.12.9 GPIOs
GPIOs are programmable as Input or Output with 3.3V TTL level. The default maximum driv-
er current is 10mA (sink and source).
XGPIO0..9 have 4.7k pull-up on module.
!!! XGPIO9 has a pull-down due to bug in processor revision. Will be changed to pull-up
when bug in processor is fixed.!!!
4.12.10 MISC signals, power
RESETBTN 3.3V TTL low active RESET input; use pushbutton to GND or open
collector driver to pull low. Don’t drive with high level.
VCC3.3, VCC5 voltage outputs for external logic, max. 100mA per pin for external
chips and functions

4.12.11 CAN Bus
As an optional feature the module does provide the CAN bus transmit and receive TTL signal
without any termination in standard version (CANRX, CANTX). Both signals are working with
3.3V level.
Needs an interface chip to the CAN bus as shown below. If not used, please left signals un-
connected.

5.4 Shield to GND connection
There is the possibility to add a shield ground to signal ground connection on both mounting
holes on front side. There are 0603 shapes on the solder side of the board to add a connection. This gives customers the possibility to change EMV characteristic. On default this parts
are not mounted and the shield ground is not connected to the signal ground.
