Orange Pi 4/B Review – A Raspberry Rival Starting at $50

Orange Pi 4 Review

First enhancement of the new Orange Pi 4 SBC board series expected to be available in about two weeks. Following the gained popularity of the Rockchip SoC solution amongst known Chinese brands such as the FriendlyElec Nano Pi M4v2 boards that are also based on the Rockchip RK3399 solution.

The new Orange Pi 4 comes with few hardware improvements worth checking. For example, a DC power input port was added for more stable power requirements with an additional USB Type-C port that can be also used to power the board. Another advantage is the 16GB eMMC chip that is soldered on the PCB so you will not have to buy a separate eMMC module.

Additional features and highlights worth mentioning are the On-board Microphone unit, Power Management Unit (PMU) chip, 4GB RAM memory, and a 24 pins PCIe Interface. As for the USB ports, In the Orange Pi 4B edition, the company decided to stick with a pair of USB V2.0 without any additional USB 3.0 host port support.

According to the company announcement, the more advanced Orange Pi 4B is more suitable for artificial intelligence (Deep learning) applications, equipped with a unique Gyrfalcon Lightspeeur 2801S AI accelerator chip/NPU (Neural Processor unit) developed by Gyrfalcon Technology Inc. In the software arena, the Orange Pi 4/B boards are expected to support Android 8x and Armbian Linux including future distributions.
