Radxa ZERO 3E 2GB RAM Single Board Computer

Radxa ZERO 3E (2GB RAM) is a high-performance single-board computer (SBC) engineered into an ultra-compact form factor (measuring just 72 × 30 mm), powered by the robust 64-bit quad-core Rockchip RK3566 system-on-chip. The "3E" iteration is specifically tailored for compact edge-computing nodes, drone ground stations, smart IoT devices, network appliances, and robotics where stable, low-latency wired connectivity is paramount.

Unlike its wireless counterpart (ZERO 3W), the ZERO 3E integrates an onboard Gigabit Ethernet port with Power over Ethernet (PoE) functionality (enabled via an optional add-on PoE HAT). This capability allows both high-speed data transmission and hardware power supply to be delivered over a single network cable. The board packs 2GB of high-speed LPDDR4 memory, an Arm Mali-G52-2EE graphics processing unit, and an integrated NPU for localized AI/ML tasks.

Multimedia and hardware connectivity include a Micro HDMI port supporting 1080p @ 60fps video output, a 4-lane MIPI CSI camera connector, a MicroSD card slot for OS booting and storage, twin USB Type-C ports (one USB 3.0 Host, one USB 2.0 OTG/Power), and a standard 40-pin GPIO header for sensor and actuator integration. It officially supports Debian, Ubuntu Linux, and Android operating systems.
