XU4 PCB revision history

LOT-ID PCB Revision Description
EL-1507 rev0.1 20150527 The first production version
EL-1510 rev0.1 20150825 Add a R99 of Pull-Down resistor on the PMIC PSHOLD signal.
Add a C289 of dummy capacitor for physical balancing the heatsink on the PCB
EL-1511 rev0.1 20150825
EL-1601 rev0.1 20150825
EL-1603 rev0.1 20151201 Added a pull-up Resistor on a UART RXD PIN.
Added a 100uF capacitor on DC JACK.
EL-1606 rev0.1 20151201 RILIM of NCP380 is changed to 6.49kΩ and USB current limits at 2A.
EL-1711 rev0.1 20170905 The Protection IC is changed from 2xNCP372 to 1xTPS259251.
The Load S/W is changed from NCP380 to MP62551.
The connect resistor of the HDMI shield pin has become 1M ohm. the next lot will be changed to 0 ohm.
EL-1908 rev0.1 20180912 Due to a PCB vendor's mistake, the PCB surface color was change to green from blue accidentally.
EL-2102 rev0.2 20191126 The HDMI level shifter IC is changed from IP4791CZ12 to TPD5S116.
This change may result in a reduction in the Short Circuit Current from 350 mA to 120 mA and
The 5V power current of sink draws less to 120mA from 140mA within 4.7V and 5.3V from source ,
Which may be insufficient for some VGA adapters that consume more current than the HDMI standard specification (50mA) or over 120mA.
EL-2108 rev0.2 20191126 Changed Q1, Q2, Q4 and Q5 from FTK7002EN to FTK7002U because of the semiconductor shortage.

We did not change the PCB revision because any key features were not changed nor added.

Display HDMI monitor
Storage (Option) MicroSD Card Slot, eMMC module socket : eMMC 5.0 HS4000 Flash Storage
Gigabit Ethernet LAN 10/100/1000Mbps Ethernet with RJ-45 Jack ( Auto-MDIX support)
Serial console port Connecting to a PC gives access to the Linux console.
You can see the log of the boot, or to log in to the C1 to change the video or network settings.
Note that this serial UART uses a 1.8 volt interface. We recommend the USB-UART module kit from Hardkernel.
Molex 5268-04a(2.5mm pitch) is mounted on the PCB. Its mate is Molex 50-37-5043 Wire-to-Board Crimp Housing.
RTC (Real Time Clock) backup battery connector If you want to add a RTC functions for logging or keeping time when offline, just connect a Lithium coin backup battery (CR2032 or equivalent).
All of the RTC circuits are included on the ODROID-XU4 by default.
Molex 53398-0271 1.25mm pitch Header, Surface Mount, Vertical type (Mate with Molex 51021-0200)
WiFi (Option) USB WIFI Modules
HDD/SSD SATA interface (Optional) SuperSpeed USB (USB 3.0) to Serial ATA3 adapter for 2.5“/3.5” HDD and SSD storage
Power (Option) 5V 4A Power
Case(Option) Mechanical case & cooler (90 x 59 x 28 mm approx. )
PCB Size 83 x 58 x 20 mm approx.

LED Indicators

The ODROID-XU4/HC1/HC2 has four indicator LEDs that provide visual feedback.

1. Red LED

  • Power: connected to 5V power (HC2:12V)

2. Blue LED

  • Alive Solid light : u-boot is running
  • Flashing : Kernel is running (heart beat)

3. Ethernet LEDs

  • Green LED Flashes when there is 100Mbps connectivity
  • Yellow(Orange/Amber) LED Flashes when there is 1000Mbps connectivity
