DDR LPDDR4X EMMC Arm Computer System On Module SoM RK3566 LCB3566 Customizable
The LCB3566 is a compact and versatile core module built on the Rockchip RK3566 platform, measuring just 62mm x 40mm. It connects to the baseboard through two Amphenol 0.8mm pitch dual-row 120Pin board-to-board connectors, secured by four M2 screws, ensuring a stable, reliable, and easy-to-maintain assembly.
Equipped with a CPU, DDR, eMMC, and PMU, the LCB3566 features the RK3566 CPU and LPDDR4 memory, known for its low power consumption and high frequency, available in 2GB, 4GB, or 8GB configurations. The eMMC storage complies with the high-speed eMMC 5.1 standard, offering capacities from 4GB to 128 GB. Its PMU integrates the RK809 with DC-DC and LDO components, supporting DVFS for optimal performance.
Designed with modularity in mind, the LCB3566 serves as a full-featured core module, providing access to all functional CPU pins. Fully tested and validated for mass production, it enables users to streamline product development, shorten project timelines, reduce costs, and boost operational efficiency.
