Just last week, we wrote about the Orange Pi 6 Plus, a powerful CIX P1 SBC that features up to 64GB LPDDR5 memory. Now, the company has introduced the Orange Pi 4 Pro, an Allwinner A733-based low-cost, low-power SBC, which is very similar to the Radxa Cubie A7A in terms of architecture, AI capabilities, and use cases.
It supports up to 16 GB of LPDDR5 RAM, eMMC modules (16–128 GB), NVMe SSD via an M.2 M-key PCIe 3.0 slot, and microSD storage. Connectivity options include Gigabit Ethernet with PoE, WiFi 6, and Bluetooth 5.4. It also features HDMI 2.0, dual MIPI CSI/DSI interfaces, USB 3.0/2.0 ports, and audio I/O. Target applications include robotics control, industrial automation, smart gateways, NAS, and more.

The company provides tools, documentation, and schematics, along with official Ubuntu, Debian, and Android images, as well as the Android source code. However, many of the links currently redirect to empty Google Drive folders. The only link that is working is the Linux source code hosted on GitHub. Since this new board uses the same SoC as the Radxa one, we can expect that it should work with the Allwinner Tina SDK 1.4.6. Allwinner/Radxa also promised mainline support for the A733, but progress appears slower than anticipated, although the datasheet, TRM, and some software documentation were released in July.
Official pricing information is as follows:
- $35 with 4GB RAM
- $40 with 6GB RAM
- $45 with 8GB RAM
- $55 with 12GB RAM
While the specs mention up to 16GB of LPDDR5, the company hasn’t provided pricing for it. Only the 4GB and 8GB variants are currently available on AliExpress (some ad blockers will hide this link). Alternatively, the 8GB RAM model is listed on Amazon, but shown as “currently unavailable”. More information can be found on the product page.
