There’s another difference between the two Ubuntu builds: The NPU version fails to support 3D and video decode acceleration on the GPU, while the non-NPU version supports it in both general software use and the bundled Google Chrome browser.

Xunlong provides two versions of the operating system image: the first includes the software necessary to make use of the Gyrfalcon Lightspeeur NPU, but is a decidedly unpolished build which crashes almost immediately due to a full root partition it fails to resize to fill the microSD card onto which it has been flashed the second, marked as “version 1.2,” offers a much smoother user experience but without the software for the Lightspeeur - though the device still presents itself to the operating system, so it’s entirely possible to install the required software and development tools yourself. Sadly, things aren’t quite as simple as picking Ubuntu 18.04 and getting on with things. Most users are likely to instead choose one of the other operating systems on offer: Downloads are provided for Debian Linux 9, Ubuntu 16.04, and Ubuntu 18.04 - and while Ubuntu 18.04 may be approaching two years old now, it’s still supported by Canonical through to April 2023. It also appears to mis-detect the CPU clusters, with the bundled benchmarking utility suggesting it is only able to run on the lower-performance quad-core cluster and not the high-performance dual-core cluster.

While all the features of the board are supported, the Android Open Source Project build supplied by Xunlong is very bare-bones - and, as you would expect, does not include Google Apps support.

Out of the box, the Orange Pi 4B is running Android 8.1 with a woeful November 2018 patch level, pre-loaded onto the eMMC flash memory.Īnyone expecting the niceties of modern - at least, as modern as two versions out of the current release can be - Android will likely be disappointed, sadly. The SoftwareĪs with its previous releases, Xunlong has prepared operating system images covering a handful of use-cases. For anyone planning to build into a metal housing, it’s a major upgrade: A simple UFL pigtail will let you bring the antenna connection outside the box cheaply and easily. That weight includes a bundled external antenna for the dual-band Wi-Fi and Bluetooth 5.0 radio, an antenna which can be easily replaced, thanks to its UFL connector, with one of your own choosing.

There’s also DisplayPort 1.2 connectivity on the USB Type-C port, along with two LCD panel connectors - one of which pulls double-duty as the board’s second MIPI Camera Serial Interface (CSI) connector.Īt 95 x 61 x 24.5mm and 48g, the board is slightly larger and heavier than a Raspberry Pi 4 Model B, though it’s a close competition. The Orange Pi 4B has an interesting dual-mode power input: It’s possible to power the board from the USB Type-C connector, as with a Raspberry Pi 4, but doing so blocks off the Orange Pi 4’s only USB 3.0 port a better choice is to use the barrel-jack connector to the lower-right of the board, which accepts a centre-pin-positive 5V 3A input and keeps the USB 3.0 port free - so long as you don’t foul against the HDMI port, at least. You’d be forgiven for missing it on a glance at the board it’s a tiny BGA package located just behind the USB 2.0 ports, altogether unremarkable to the eye. It’s not the SoC which makes the Orange Pi 4B stand out from the competition: It’s the Lightspeeur 2801S neural processing unit (NPU), a deep-learning-centric accelerator designed and built by Gyrfalcon Technologies. Another Orange Pi 4B feature that Raspberry Pi lacks is PCI Express support, available via a ribbon-cable connector to an optional breakout board. Raspberry Pi 2 with external USB 3.0 SSD Pi StateĪb -n 100 -c 10 (uncached), 1x USB 64GB SSDĪlso, as a point of reference, when you power off a Raspberry Pi (any model), it typically uses 20-30 mA (0.1W) until you physically disconnect the power.There’s 4GB of dual-channel LPDDR4 memory on-board, along with 16GB of eMMC storage - something which has long been requested from the consumer-centric Raspberry Pi range but not yet supplied.
I will be adding power consumption statistics to this page as time goes on. I use the USB Charger Doctor to measure power consumption with the Dramble and individual Raspberry Pis.
