In December when Shenzhen Xunlong Software announced its open-spec, Linux- and Android-ready Orange Pi and Orange Pi Mini SBCs, both of which use the dual-core, Cortex-A7 Allwinner A20 system-on-chip, the company also briefly noted an upcoming, quad-core Orange Pi Plus. The Plus was said to offer a quad-core, Cortex-A7 Allwinner A31 SoC with a PowerVR SGX544MP2 GPU. Instead, the shipping version, now available at TinyOne Systems, arrives with Allwinner’s new quad-core Cortex–A7 based H3SoC and a Mali-400 MP2 GPU.
The Allwinner H3 SoC, which is available for only $6 in volume, primarily targets low-cost, OTT set-top boxes (STBs). The H3 has a faster 1.6GHz clock rate than the 1GHz A31, although the Mali-400 MP2 is slower than the PowerVR. (The Mali GPUs, however, are also more open to developers.) The H3 supports H.265/H.264 4K hardware acceleration at up to 30fps, as well as 4K video point-to-point HDMI output, says Allwinner.
Although Shenzhen Xunlong previously had no I/O details of the board, the photos provided at the time show the port layout has been completely changed. Instead of going with the split expansion connectors, with one of them a Raspberry Pi Model B-compatible 26-pin connector, it now mimics the Orange Pi Mini in offering a 40-pin connector that is claimed to be compatible with add-on boards designed for the Pi Model B+. The new Raspberry Pi 2 Model B likewise has a 40-pin connector that’s compatible with that of the Pi Model B+, and that also provides backwards compatibility with the 26-pin of the first-gen Pi Model B.
The Orange Pi Plus ships with 1GB RAM and a microSD slot, as well as WiFi and gigabit Ethernet networking. You get four USB 2.0 host ports plus a micro-USB OTG port that can be used to power the 5V SBC. Other features include HDMI, CVBS, audio, and CSI camera connections.
The SBC is said to be open source, with a variety of Linux and Android builds available, but as CNXSoft notes, all the resource locations are either empty or have code targeted for the earlier A31 version. The SBC won’t ship for another month, however, so we’ll give them the benefit of the doubt.
Still, the whole operation seems a little slipshod. For example, when you click on the detail images of the Orange Pi Plus posted on the product page to get a closer view, they instead switch you to the detail images of the old A31 version.
The Orange Pi Plus offer extras not found on the RPi 2, including SATA, gigabit Ethernet, WiFi, and with the Plus, a generous 8GB of eMMC flash, but the gap has closed considerably.
