3/ Installation procedure
3.1. Installing the Board
ESD Sensitive Device!
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry.
•Wear ESD-protective clothing and shoes
•Wear an ESD-preventive wrist strap attached to a good earth ground
•Check the resistance value of the wrist strap periodically (OK: 1 MΩto 10 MΩ)
•Transport and store the board in its antistatic bag
•Handle the board at an approved ESD workstation
•Handle the board only by the edges
To get the board running follow these steps. If the board shipped from Kontron has already components like RAM
and CPU cooler mounted, then relevant steps below can be skipped.
1.
Turn off the PSU (Power Supply Unit)
Turn off PSU (Power Supply Unit) completely (no mains power connected to the PSU)
or leave the Power Connectors unconnected while configuring the board. Otherwise
components (RAM, LAN cards etc.) might get damaged. Make sure to use +5V single supply
only. Alternatively use a standard ATX PSU with suitable cable kit and PS_ON# active.
2.
Cooler Installation
Normally the cooler is premounted, but in case not, then make sure that the heat paste etc. on the cooler is
intact and cover the full area of the SoC. Connect cooler fan electrically to the FAN_CPU connector.
3.
Connecting Interface
s
Insert all external cables for keyboard etc.
4.
Connect and turn on PSU
Connect PSU to the board by the ATX+5 V-4pin connector or alternatively connect an external 5 V DC power
adapter to the rear DC jack.
5.
U-Boot Setup
Enter the U-Boot setup, more information in Chapter 7/.
6. Mounting the board in chassis

pITX-iMX8M – Rev. 0.7 Preliminary
www.kontron.com // 16
When mounting the board to chassis etc. please notice that the board contains components
on both sides of the PCB which can easily be damaged if board is handled without
reasonable care. A damaged component can result in malfunction or no function at all.
When fixing the Motherboard on a chassis it is recommended to use screws with integrated washer and a
diameter of >7 mm. Do not use washers with teeth, as they can damage the PCB and cause short circuits.
3.2. Requirements IEC60950-1
Take care when designing chassis interface connectors in order to fulfil the IEC60950-1 standard. Users of pITX-
iMX8M must evaluate the end product to ensure compliance the requirements of the IEC60950-1 safety standard
are met:
The motherboard must be installed in a suitable mechanical, electrical and fire enclosure.
The system in its enclosure must be evaluated for temperature and air flow considerations.
The motherboard must be powered by a CSA or UL approved power supply that limits the maximum input
current to 6A to an external 5 V locking barrel-type DC jack or to an internal 5 V 4-pin DC power
connector.
For interfaces having a power pin such as external power or fan, ensure that the connectors and wires are
suitably rated. All connections from/to the product shall be with SELV circuits only.

Power Supply Specifications
Voltage Ripple Voltage Ripple maximum 100 mV peak to peak 0-20 MHz
Rise Time 2 ms to 20 ms rise time from input voltage <10% to nominal VCC
If any of the supply voltages drops below the allowed operating level longer than the
specified hold-up time, all the supply voltages should be shut down and left OFF for a time
long enough to allow the internal board voltages to discharge sufficiently.
If the OFF time is not observed, parts of the board or attached peripherals may work
incorrectly or even suffer a reduction of MTBF.
The minimum OFF time depends on the implemented PSU model and other electrical factors
and needs to be measured individually for each case.
