Radxa ROCK 3 Compute Module (Radxa CM3) 8GB LPDDR4 RAM Lite — Rockchip RK3566 Quad-Core SoC (Raspberry Pi CM4 Pin-Compatible Form Factor)
For sale is a brand-new, unused Radxa ROCK 3 Compute Module (Radxa CM3) equipped with 8GB of high-speed LPDDR4 RAM.
This module was originally purchased for a bespoke embedded development project that was never started, and has remained securely stored in an anti-static bag.
The Radxa CM3 is an ultra-compact system-on-module (SoM) powered by the Rockchip RK3566 Quad-Core 64-bit ARM Cortex-A55 processor, integrated with an ARM Mali-G52 GPU and a dedicated 0.8 TOPS NPU (Neural Processing Unit) for edge AI and computer vision tasks.
Engineered with the standard dual 100-pin board-to-board footprint, it functions as a powerful, feature-rich alternative to the Raspberry Pi Compute Module 4 (CM4), offering drop-in physical compatibility with standard CM4 carrier boards while providing an additional third connector for extended RK3566 I/O.
High-End 8GB LPDDR4 Configuration: Max-capacity 8GB RAM handles intensive multi-container Docker workloads, edge AI inference, virtualization, and media transcoding.
Rockchip RK3566 Performance: Features four high-efficiency 64-bit Cortex-A55 cores clocked up to 2.0 GHz, outperforming standard low-power embedded modules.
Dedicated 0.8 TOPS NPU: On-chip neural processing unit supports INT8/INT16 AI acceleration for real-time object detection, face recognition, and machine learning models.
Lite Edition Flexibility: Operates via carrier board MicroSD sockets or PCIe NVMe solid-state drives for customizable, high-speed OS storage.
Raspberry Pi CM4 Ecosystem Compatibility: Fits standard Raspberry Pi CM4 baseboards, carrier boards, router boards (like Waveshare dual Ethernet boards), and industrial enclosures.
Extended I/O Capabilities: Features a 3rd high-density connector delivering supplementary RK3566 native signals (SATA, extra USB, and PCIe lanes) when mounted on specialized Radxa baseboards.
Onboard Gigabit Ethernet PHY: Equipped with an integrated Realtek RTL8211F transceiver for native Gigabit networking.
