A38X MicroSom
Description
SolidRun’s leading System on a Module (38x-MicroSoM™) family is designed for embedded systems product developers and OEMs. SolidRun has packed a Marvell ARMADA 38x SoC (System-on-Chip), memory subsystem, I/O and interconnected subsystems into a single ultra-compact System-on-Module sized at 35mm x 50mm. The MicroSoM is available in a variety of power, memory and storage configurations, offering engineers a unique set of off-the-shelf design features and benefits such as faster time to market, lowers design costs and reduced risks.
