Introduction
In the rapidly evolving human-machine interface (HMI) application market, as technology continues to innovate and cost control requirements increase, customers’ demands for device size and customization are growing, especially in fields such as medical and industrial automation, where the pursuit of miniaturization, high performance, and high customization solutions has never stopped.
With the increasing popularity of the Arm platform, more and more customers seeking efficient and flexible solutions are inclined to choose Arm core boards to meet the needs of HMI embedded in various application scenarios. Miniaturized Arm core boards have become urgently needed products for HMI customers.
A certain client needs to develop an HMI device with dual display functionality. One LVDS serves as the main display interface for the HMI, while another HDMI is used for extended screen display. Additionally, the device needs to support two RS485 and CAN communications to connect to the field’s lower machine devices. At the same time, the client also hopes that the device can connect to the server via wired and wireless networks.
Since this client requires the overall thickness of the HMI device to be controlled within 2cm, a smaller main control size is needed. Considering costs, the client does not use ODM and only accepts core board or single board solutions. This poses a challenge for the selection of the main control of the device.
Facing the extremely challenging requirements, Advantech provides a ROM-2820 solution based on the i.MX93 OSM size-L core board. This core board is equipped with two high-performance A55 cores that can support the client’s complex software applications. In terms of hardware resources, the core board is designed with four UART interfaces, allowing customers to flexibly expand various serial port resources such as RS485 and RS232; at the same time, the CAN resources provided by the i.MX93 platform can also meet the client’s industrial communication requirements.
In terms of network connectivity, the i.MX93 core board not only provides the possibility of RJ45 Ethernet connection but also supports WiFi or 4G connection, ensuring that the device can seamlessly connect to the server. Most importantly, the size of the ROM-2820 core board is only 45*45mm, with a thickness of 1mm. It adopts the OSM standard specification and uses LGA packaging. Compared to core boards with connector solutions, the ROM-2820 is soldered onto the motherboard through SMT, making the OSM solution (core board + motherboard) thinner in size and thickness than traditional connector-connected core board + motherboard solutions, providing valuable space for customers to design more compact and flexible HMI products.
⭐Compact size, strong adaptability: The size of the ROM-2820 core board is 45x45mm, with a thickness of only 1mm, making it very suitable for application scenarios with strict size limitations, such as portable devices and embedded systems, effectively saving space.
⭐LGA packaging and SMT soldering technology: Using LGA packaging, it is directly soldered onto the motherboard through SMT (surface mount technology). Compared to traditional core boards connected with connectors, it greatly reduces the overall height of the board and improves the product’s compactness and stability.
⭐No need for ODM: The ROM-2820 is the smallest core board, with only four key components: CPU, DDR, EMMC, and PMIC, with no other bridging chips or connectors, and the size is very small. Therefore, using the OSM core board can achieve effects close to ODM—by designing the motherboard, it can achieve the same product effect as customized ODM single boards.
⭐ Powerful processing capability: The ROM-2820 is equipped with the i.MX93 processor platform, which includes two A55 cores, ensuring efficient data processing capability and meeting the needs of various complex applications.
⭐AI computing power support: With 0.5 TOPS of AI computing power, the ROM-2820 can support various lightweight AI applications such as smart recognition and data analysis, providing hardware support for AI edge computing.
⭐ Diversified communication interfaces: Supports network, CAN, serial ports, USB, GPIO, etc. These rich interfaces allow the ROM-2820 to easily connect to various peripherals and modules, meeting a wide range of application needs.
⭐Meet customer expansion needs: Whether in industrial automation, vehicle systems, smart homes, or other customized applications, the ROM-2820 can provide sufficient resources to meet customers’ functional expansion needs.
⭐Standardized design: The ROM-2820 adopts the OSM (Open Standard Module) standard, which means that it follows industry standards in design and manufacturing, ensuring high compatibility with other devices or components that adhere to the same standard.
⭐Easy future upgrades: A standardized design also means that in the future, when upgrading or expanding the system, users can more easily find compatible solutions, reducing the cost and complexity of long-term maintenance and upgrades.
In summary, the ROM-2820 core board, with its compact size, powerful processing capability, rich interface support, and standardized design, provides customers with a highly flexible and outstanding embedded solution. Whether used in strictly demanding industrial environments or highly integrated consumer electronics products, the ROM-2820 can provide stable and reliable performance support. Additionally, for the OSM core board, Advantech also offers corresponding OSM Design-in services to help customers successfully complete product development.
Advantech’s miniaturized ARM core board products and flexible customization services provide customers with high performance, highly customized, and compact core board solutions, not only helping customers overcome design challenges but also opening the door to market success.
