Libre Computer AML-S905X-CC (Le Potato) vs Rock Pi 4 Model B
Side-by-side comparison of features, pricing, ratings, and alternatives.
Le Potato is a low‑cost single‑board computer built around the Amlogic S905X quad‑core Cortex‑A53 processor. It offers full 4K video playback, a rich set of I/O, and full Linux support, making it ideal for media centers, embedded controllers, and development platforms. The board is fully open‑hardware, with schematics and software sources publicly available, and it runs mainline Linux kernels and Android images out of the box. Designed for flexibility, Le Potato includes HDMI 2.0, Gigabit Ethernet, USB 2.0, a 40‑pin GPIO header, and optional Wi‑Fi/BT modules. Its small footprint (≈ 85 mm x 56 mm) and low power draw allow it to be integrated into custom enclosures, robotics, or headless servers, while community‑driven support provides a wealth of tutorials and pre‑built images.
The Rock Pi 4 Model B is a single‑board computer built around the Hexa‑core Rockchip RK3399 processor, offering up to 4 GB LPDDR4 RAM, dual‑channel eMMC, and a full‑size HDMI 2.0 port for 4K@60Hz output. Its compact 85 mm × 56 mm board includes USB‑C Power Delivery, USB‑3.0, Gigabit Ethernet, Wi‑Fi 802.11ac and Bluetooth 5.0, making it suitable for both headless servers and media‑center projects. Designed for hobbyists, developers, and edge‑AI applications, the Rock Pi 4 supports Linux, Android, and various open‑source OS images. The board’s GPIO header, PCIe‑x1 lane (via M.2 slot), and optional carrier boards enable expansion into robotics, AI inference, and networking appliances.
