Quick View of DSOM-090M-I SoM
The DSOM-090M-I is an advanced System-on-Module (SoM) developed by Dusun, featuring the powerful MT7621A processor from MTK. With its dual-core MIPS1004Kc running at a maximum clock speed of 880MHz, this module is designed to excel in various applications, including internet service routers, wireless routers, home security gateways, NAS services, and switch control processors. Its high-performance capabilities and extensive connectivity options make it an ideal choice for developers seeking to create innovative IoT solutions.
The MT7621 System on Module is a versatile and powerful platform for developing networking and security solutions. The dual-core architecture enables efficient multitasking and handling of complex network traffic. It can be customized and configured to meet the specific needs of a wide range of applications, from small home networks to large enterprise deployments.
The main difference between the DSOM-090M-I and DSOM-090M-J lies in the storage capacity of the eMMC (embedded MultiMediaCard) used. The DSOM-090M-I is equipped with a 4GB eMMC, while the DSOM-090M-J features an 8GB eMMC. The SOM-090M-I with a 4GB eMMC may be a more cost-effective option compared to the DSOM-090M-J with an 8GB eMMC. If the application does not require a large amount of storage space, opting for the 4GB eMMC variant can help save costs.
