Optional Audio Jacks
Optionally, SBC-A62-J board can be equipped with an optional AC
’
97 Audio Codec, Realtek ALC655.
In this case, the module will have two standard stereo audio jacks.
The light green audio jack will be the Headphone out (not amplified), while Pink Audio jack is the Mic In Jack.

CAN Bus connector
The i.MX6 processor includes two Flexible Controller Area Network (FlexCAN).
For this reason, as a factory option, on the SBC-A62-J board it is possible to have a CAN transceiver, for the direct connection of the board to a CAN Bus
network.
This interface is compliant to CAN specifications rel. 2.0 part B. The transceiver used is designed for high-speed (up to 1Mbps)
CAN applications, and also offers improved EMC and ESD performances.
CAN Bus Connector is a 4-pin single line SMT connector, type MOLEX 53398-0471 or equivalent, with pinout
shown in the table on the left. Mating connector: MOLEX 51021-0400 receptacle with MOLEX 50079-8000
female crimp terminals.
CAN_H: High-Level CAN bus line.
CAN_L: Low-Level CAN bus line.
A 120
Ω
termination resistor is placed between CAN_H and CAN_L signals. It can be connected or disconnected from the line
by using JP2 jumper (Jumper inserted = termination connected).
When the CAN transceiver is not mounted as a factory option, it is possible to use the FlexCAN1 interface, at TTL level, through the expansion connector J8, port
#3. Please notice that the CAN trans connector CN24 and the availability of CAN interface on J8 are mutually exclusive. Please also check par. 3.3.15.
3.3.11
Optional FAN/GPIO connector
To allow the integration of a SBC-A62-J based system inside a box PC-like, there is an optional connector on the
carrier board that can be used to drive an external FAN, if needed.
The dedicated connector is a 3-pin male connector, type MOLEX p/n 53398-0371 or equivalent, with
pinout shown in the table on the left.
Mating connector: MOLEX 51021-0300 crimp housing with MOLEX 50079-8000 crimp terminals.
This connection is rated for a maximum current of 300mA.
GPIO1_11 is the signal, managed by i.MX6 processor
’
s pad F19, which can be used as a tachometric fan input.
