Modern industrial embedded projects demand hardware that balances stable performance, rich peripheral interfaces, wide‑temperature operation and reasonable cost. Among Rockchip’s product lineup, the RK3568 industrial SOM stands out as a mainstream solution widely adopted by system integrators, OEM manufacturers and hardware developers. Whether you are evaluating RK3568 SOM, SBC, or development board for IoT gateway, HMI, or industrial control equipment, understanding its hardware capabilities, real‑world deployment limits and mass‑production notes can help you avoid costly design mistakes. This article covers core specs, typical use cases, hardware comparison, purchasing considerations and frequently asked questions for RK3568 industrial SOM.
What Is RK3568 Industrial SOM
RK3568 industrial SOM is a system‑on‑module built around Rockchip RK3568 quad‑core Cortex‑A53 processor. It integrates CPU, GPU, memory, flash storage, power management circuit and essential peripheral circuits onto a compact module. Designers only need to develop a simple carrier board to bring out Ethernet, RS485, CAN, USB, display and camera interfaces, instead of designing the complex core circuit from scratch.
Different from general‑purpose RK3568 SOM, the industrial version passes stricter screening for chips and components. It supports wide‑temperature working range, better anti‑interference performance and long‑term component supply, which is critical for industrial scenarios that run 24‑7 non‑stop. Many teams confuse RK3568 SOM, RK3568 SBC and RK3568 development board. Each form factor fits a different project stage. A development board is for early‑stage software evaluation and prototype testing. SBC is a complete single‑board computer ready for quick deployment. Industrial SOM targets formal mass‑production, letting customers customize carrier boards to match enclosure and interface requirements.
Core Hardware Specifications of RK3568 Industrial SOM
The RK3568 chip adopts 22nm process, quad‑core Cortex‑A53 up to 2.0GHz, paired with Mali‑G52‑2EE GPU. It supports hardware decoding of 4K video, multi‑channel MIPI display and MIPI camera input. Rich built‑in peripherals include dual Gigabit Ethernet, SATA 3.0, PCIe 2.1, multiple UART, SPI, I2C, CAN bus. These interfaces cover most requirements of industrial control, data acquisition and edge gateway hardware.
Below is a comparison of three common hardware forms based on RK3568 platform.
| Item | RK3568 Industrial SOM | RK3568 SBC | RK3568 Development Board |
|---|---|---|---|
| Main usage | Mass‑production custom hardware | Fast deployment without custom PCB | Prototype and software development |
| Customization | Match self‑designed carrier board | Limited hardware modification | Almost no hardware modification |
| Industrial temperature grade | Wide‑temperature component option | Mostly commercial grade | Commercial grade only |
| Supply cycle | Long‑term industrial supply | Depends on SBC vendor | Short‑term evaluation supply |
| Cost characteristic | Low unit cost for large batch | Higher unit price | Higher price for small quantity |
RK3568 industrial SOM supports flexible RAM and Flash configuration. Common combinations include 2GB+8GB, 4GB+16GB. When selecting hardware configuration, do not blindly pursue higher specifications. RAM size should match operating system and application load. Light‑load gateway tasks can run well with 2GB memory, while projects running multi‑stream video decoding and complex application software need 4GB or above.
Typical Industrial Applications for RK3568 Industrial SOM
Thanks to balanced computing power, abundant industrial interfaces and cost advantages, RK3568 industrial SOM covers multiple vertical industries.
Industrial HMI and on‑site control terminals is one of the largest markets. The module drives local touch display, collects field sensor data through RS485 and CAN bus, and uploads data to cloud platform via Gigabit Ethernet. It can run Android or Linux systems to realize human‑machine interaction and local logic processing.
Industrial IoT edge gateway is another mature scenario. Dual Gigabit Ethernet port supports network isolation between internal industrial network and external network. Multiple serial ports connect PLC, sensors and acquisition modules to complete protocol conversion, data preprocessing and edge computing, reducing cloud computing pressure.
Smart retail and self‑service equipment also widely use RK3568 SOM. Vending machines, self‑service kiosks use its video decoding capability to drive advertising display, meanwhile collect device status and transaction data.
Besides, it works for smart security access control, industrial visual auxiliary detection and transportation monitoring terminals. Compared with higher‑performance RK3576 SOM, RK3568 is more cost‑effective for non‑AI‑heavy industrial tasks. For projects requiring powerful local AI inference, hardware teams will evaluate RK3576 SOM as an alternative solution.
Key Points When Selecting RK3568 Industrial SOM
Many buyers focus only on RK3568 SOM price during procurement, ignoring industrial‑grade details, which leads to product instability after mass production. Several critical factors deserve attention.
First confirm component grade and temperature range. Ask suppliers whether core chips, memory and flash are industrial‑grade components, and confirm actual working temperature range. Commercial components may crash or fail under high or low temperature in factory environment.
Second, verify long‑term supply guarantee. Industrial equipment often requires 5‑10‑year component supply cycle. Some suppliers sell spot goods assembled with stock components, and cannot guarantee continuous supply after chips stop production. You need to confirm vendor’s component supply plan before formal project launch.
Third, evaluate technical support completeness. Good SOM vendors should provide complete BSP, schematic reference, carrier board design guide and technical documentation. Poor BSP support will bring huge workload to software development. When comparing vendors such as Forlinx RK3568 solutions, you should compare BSP update frequency, document completeness and after‑sales response speed instead of comparing price alone.
Fourth, confirm system support. RK3568 industrial SOM commonly supports Linux, Buildroot and Android. Confirm whether your required OS version has stable BSP before ordering samples.
Frequently Asked Questions
Q1 What is the difference between RK3568 SOM and RK3568 development board
A: RK3568 development board is a complete evaluation platform with carrier board, interfaces and heat sink, mainly for early software development and function verification, not designed for mass‑production. RK3568 industrial SOM is the core computing module. Developers design their own carrier board according to product requirements, suitable for formal batch production.
Q2 Can RK3568 industrial SOM run AI inference tasks
A: RK3568 has no dedicated high‑performance NPU. It supports lightweight AI algorithm inference through CPU and GPU. If you need large‑scale multi‑channel AI analysis, consider upgrading to RK3576 SOM.
Q3 How about RK3568 SOM price
A: RK3568 SOM price changes according to RAM, Flash configuration, component grade and order quantity. Industrial‑grade wide‑temperature version costs higher than commercial version. Batch quotation is suggested after confirming hardware specification. Do not select ultra‑low‑price modules with unknown component sources for industrial projects.
Q4 Is RK3568 industrial SOM compatible with Forlinx RK3568 carrier board
A: Different vendors use different pin definitions for SOM modules. Direct compatibility cannot be guaranteed. Even if the chip model is the same, you cannot directly use other brands’ carrier boards. Please follow your module supplier’s reference design.
Q5 What operating systems does RK3568 industrial SOM support
A: Mainstream supported systems include Android 11, Linux Debian, Buildroot. Actual available system versions depend on vendor BSP development status. Confirm SDK situation before sample purchase.
Final Thoughts
RK3568 industrial SOM has become a reliable mainstream embedded hardware option for countless industrial IoT, HMI and edge gateway projects, relying on mature chip solution, rich peripheral resources and controllable cost. When starting a new project, do not only compare RK3568 SOM price. You need to comprehensively evaluate component grade, long‑term supply, BSP technical support and carrier‑board design service. For projects with higher AI performance requirements, make parallel evaluation with RK3576 SOM. Sample testing and long‑time stability test before mass production can effectively avoid later‑stage project risks.
