RADXA Zero
Powered by a Amlogic S905Y2 64bit quad core processor
The Radxa Zero is an ultra-thin, small-form-factor single-board computer (SBC) designed to deliver powerful performance in a pocket-sized footprint. Powered by the Amlogic S905Y2 quad-core Cortex-A53 processor and an Arm Mali-G31 MP2 GPU, this versatile board is capable of handling complex multimedia tasks, image processing, and lightweight edge computing workloads. It supports various configurations of high-speed LPDDR4 RAM and robust onboard eMMC 5.1 storage, serving as an incredibly capable alternative to traditional minimalist development boards. Capable of smoothly running both Android and various customized Linux distributions (such as Radxa OS based on Debian), it bridges the gap between raw maker hardware and user-friendly computing.
Despite its minuscule size—measuring just 65mm by 30mm—the Radxa Zero includes an impressive array of connectivity and expansion features. For peripheral mapping, it offers a Raspberry Pi-compatible 40-pin GPIO header that accommodates essential interfaces like UART, SPI, I2C, and PWM. Multimedia output is achieved via a Micro HDMI port that pushes crisp 4K resolutions at 60 frames per second, backed by hardware-accelerated H.265/VP9 decoding. Dual-mode Wi-Fi and Bluetooth ensure seamless wireless connectivity, while its unique dual USB Type-C setup splits operations neatly between a dedicated USB 3.0 host lane and a flexible USB 2.0 OTG port that handles both data and power delivery.
