Shenzhen Xunlong Software has officially launched the latest single-board computer (SBC) in the Orange Pi family, offering a Rockchip RK3399 six-core processor and optional Gyrfalcon Lightspeeur 2801S neural accelerator for artificial intelligence at the edge.
First spotted by Linux Gizmos, the Orange Pi 4 and Orange Pi 4B — the latter including the Lightspeeur 2801S NPU, which adds a 2.8 TOPS co-processor for neural network workloads, but otherwise being identical to the non-B variant — is based around Rockchip's RK3399 system-on-chip, which includes two Arm Cortex-A72 cores running at up to 2GHz and four slower Cortex-A53 cores. Graphics are handled by an Arm Mali-T864 graphics processor, with support for OpenGL ES versions through to 3.1 plus OpenVG 1.1 and OpenCL, and there's 4GB of LPDDR4 memory on board plus the option of adding 16GB of eMMC flash memory.
Networking capabilities are handled by a Realtek gigabit Ethernet controller plus an Ampak AP6256 802.11b/g/n/ac and Bluetooth 5.0 radio module. The board also includes a single HDMI 2.0a video output supporting 4K resolutions at 60Hz, a single DisplayPort 1.2 with the same resolution capabilities, and dual MIPI-DSI offering four lines per channel. There's analogue audio in and out via a 3.5mm jack, two MIPI-CSI camera connectors — though one is shared with the second camera port - one each of USB 2.0 and USB 3.0 host ports, and one USB 3.0 Type-C port.
Impressively, the board also includes a 24-pin PCI Express connector for high-speed interface to external hardware, an on-board microphone, a Raspberry Pi-style 40-pin general-purpose input/output (GPIO) header, microSD storage expansion, and a barrel-jack power connector.
As with most Orange Pi-family launches, however, software support is still somewhat up in the air. Xunlong claims the board supports Android 8.1, Ubuntu 16.04, Ubuntu 18.04, and Debian 9; at the time of writing, however, only a Debian server image and an unspecified Ubuntu desktop release were listed for public download.
The boards are available to order now from the purchase link on the official Orange Pi website, priced at $62.99 for the Orange Pi 4 and $74.29 for the NPU-equipped Orange Pi 4B.
