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.

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

Gigabit Ethernet LAN10/100/1000Mbps Ethernet with RJ-45 Jack ( Auto-MDIX support)
Serial console portConnecting 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 connectorIf 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 IEEE 802.11b/g/n 1T1R WLAN with Antenna (USB module)
HDD/SSD SATA interface (Optional)SuperSpeed USB (USB 3.0) to Serial ATA3 adapter for 2.5“/3.5” HDD and SSD storage
Power (included)5V 4A Power
Case(Option)Mechanical case & cooler (90 x 59 x 28 mm approx. )
PCB Size83 x 58 x 20 mm approx.

LED Indicators

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

1. Red LED

  • Power: connected to 5V power

2. Blue LED

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