Delivering Power-efficient and Ultra-compact Technology with Advantech OSM Computer-on-Module for Smart Parking Meters

ROM-2620, Advantech Open Standard Module powered by NXP i.MX 8ULP, for Smart Parking Meter

Modern cities grapple with a wide range of challenges, encompassing concerns related to quality of life, energy efficiency, urban transportation, and various others. Smart city solutions provide effective strategies for addressing these urban issues. As a result, many cities are integrating smart parking meters into their broader smart city infrastructure. This transition is prompted by the need to reduce labor and operational expenses for continuous service, while also benefiting from streamlined device management.

Challenges and Demands

  • Compact design for the space-constrained urban environments.
  • Energy-efficient operation with suspend and instant wake-up modes.
  • Edge inferencing for vehicle number plate recognition.
  • Low power consumption to optimize solar-powered battery storage systems.
  • 24/7 device operation and management.   

Solutions and Technologies

  • Ultra-thin and compact open standard module measuring just 30 x 30 mm. 
  • Utilizes a heterogeneous processing architecture featuring an Arm-based CPU and MCU, achieving exceptionally low power consumption (<35 μW) in sleep mode.
  • Supports MIPI-CSI and MIPI-DSI, allowing for resolutions of up to 1080P, ideal for camera and display integration.
  • Includes NXP software support: eIQ for AI application development and EdgeLock Secure Enclave for enhanced data transmission security.
  • Features Advantech DeviceOn software, enabling remote control and monitoring of the parking meters.


  • Suitable for cost-effective, large-scale deployment in space-constrained environments.
  • Power consumption is optimized for extended battery-powered device operation.
  • Easily manage over-the-air (OTA) software updates at scale.


  • OSM Size-S (30 x 30mm) with NXP i.MX 8ULP
  • Power efficient at less than 35uW with 2 x Cortex-A35 @1.0GHz, and  Cortex-M33 @216MHz
  • Featured I/O including 1 x Fast Ethernet, 2 x USB 2.0, 5 x UART, 1 x CAN,  24 x GPIO
