CAN
The COM_ETH-V1 satellite card supports a CAN interface on board via a DE-9 connector (X320). A CAN
transciever (U320) is connected to the CPU via the 80-pin satellite connector.
The CAN bus on board has a 120 Ohm termination resistor.

IO Expander
The COM_ETH-V1 satellite card supports GPIO expansion though I2C IO-Expander on board (U230). The I2C
address for the IO expander device is 0x1001100X. The satellite card supports 8 such GPIO‟s. All the GPIO‟s
are connected to LEDs (V230-V237) and SMD-Pads (TP230 – TP237). The table below gives the GPIO channel
and corresponding LED/PAD mapping.

Power
The COM_ETH-V1 satellite card can be supplied by an external power supply (24 V / 1 A) to be connected to
the power jack X240 or by a 5 V supply via the 80-pin COM satellite connector. An external power supply is
necessary only in case the current coming via the COM satellite connector is not sufficient.
A DC-DC converter on board (U240) steps down the input voltage from the power jack X240 to 5 V (VDD5). The
input voltage can be in the range from 12 V to 24 V. An on board linear voltage regulator is generating a 3.3 V
(VDD3.3) power supply out of the VDD5.
