Xunlong Orange Pi Plus

Orange Pi Plus is a H3 based development board produced by Xunlong, released in February 2015. It comes with onboard 8 GB eMMC flash, gigabit Ethernet, and 802.11 b/g/n WiFi, Video Outputs (HDMI with CEC, CVBS, simultaneous output to both) and a Raspberry Pi A+/B+ style 40 pin GPIO header. An upgraded version Orange Pi Plus 2 with twice the RAM and onboard flash was later released.

= Identification = The PCB has the following silkscreened on it: Orange Pi Plus

= Expansion Port =

The Orange Pi Plus has a Raspberry Pi model B+ compatible 40-pin, 0.1" connector with several low-speed interfaces.

= Tips, Tricks, Caveats =

FEL mode
The button marked SW3, located between the HDMI and SATA, triggers FEL mode when pressed during boot. (SW3 pulls the H3 BOOTSEL pin to low level.)

To verify you have successfully entered FEL mode, check the output of. For the Orange Pi Plus, it should look like: AWUSBFEX soc=00001680(unknown) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000

LEDs
For those with a transparent case (or no case at all) the Orange Pi Plus's LED activity is good. The red power LED (D7) can be turned off.

SATA
Be aware that the H3 SoC used on the Orange Pi Plus isn't SATA capable and therefore the SATA port is provided by a slow USB-to-SATA-bridge (especially write speeds are substandard and do not exceed 15 MB/s). This means you can neither expect SATA performance nor full SATA functionality. While the used GL830 bridge supports S.M.A.R.T. attributes it does not support S.M.A.R.T. status notification (overall health indicator of the disk – instead of PASSED or FAILED you will only get SMART Status not supported: Incomplete response, ATA output registers missing).

If you wish to connect a SATA drive (2.5" mobile harddisk or SSD) to the Orange Pi Plus: Make sure your power supply is connected to the "DC-IN" port, and can deliver sufficient current (e.g. 5V/2000mA). Using the OTG port or an inadequate power supply might result in your board not being working. You should also note that the board's SATA-power connector uses the same polarity as other Orange or Banana Pis. Therefore cable kits from CubieTech and LinkSprite that use the same jack are incompatible due to inverted polarity.

DRAM clock speed limit
DRAM is clocked at 672 MHz by the hardware vendor. But the reliability still needs to be verified. One of the ways of doing reliability tests may be https://github.com/ssvb/lima-memtester/releases/tag/20151207-orange-pi-pc-fel-test (it checks the Orange Pi PC DRAM setup in the current mainline U-Boot v2016.01-rc2 + a bugfix).

NOTE: While this test image was made for the Orange Pi PC, it also runs on the Orange Pi Plus.

See the Orange Pi PC DRAM clock speed limit for how to perform an analysis of these results.

Locating the UART
The UART pins are located between MIC and audio input of the board. They are marked as TX, RX and GND on the PCB. Just attach some leads according to our UART Howto.

= Variants =


 * The original Orange Pi was released in November 2014. The Orange Pi features a standard TF card slot and a 26 pin GPIO connector (similar to the Raspberry Pi A/B).
 * An upgraded version Orange Pi Plus 2 with twice the RAM and onboard flash was later released.
