Avalue ECM-PTL 3.5-Inch Micro Module for Edge AI Computing

The ECM-PTL micro module is designed to support edge computing requirements through a heterogeneous architecture that integrates a Central Processing Unit (CPU), Graphics Processing Unit (GPU), and a dedicated Neural Processing Unit (NPU). This configuration allows for the distribution of computational tasks across specialized hardware components. The NPU is specifically engineered to manage sustained artificial intelligence workloads and real-time inference, which reduces the operational demand on the CPU and GPU. This technical approach addresses the requirements of machine vision, automated surveillance, and industrial robotics where continuous processing and power efficiency are necessary.

Memory and Expansion Capabilities
To facilitate the deployment of data-intensive applications, the module incorporates high-speed DDR5 memory support via a SO-DIMM slot, allowing for capacities up to 48GB at 7200MHz. Scalability is managed through various expansion interfaces, including an M.2 Key M slot with PCIe Gen5 support for high-performance NVMe storage. Additionally, M.2 Key B and Key E slots provide pathways for integrating 5G, WWAN, GNSS, and Wi-Fi modules. These expansion options allow the hardware to be configured for specific connectivity or storage needs in diverse industrial environments.

Interface Integration and Visualization
The platform supports up to four independent displays, utilizing a combination of DisplayPort, HDMI, and USB Type-C with DisplayPort functionality. Internal display options include 2CH LVDS or eDP interfaces, making the system compatible with various human-machine interface (HMI) and digital signage configurations. For network communication, the module is equipped with dual Intel 2.5GbE LAN controllers, providing the bandwidth required for low-latency data transmission. Peripheral support is provided through multiple USB 3.2 and USB 2.0 ports, alongside COM ports for RS-232, 422, and 485 serial communication.

Industrial Design and Reliability Standards
The ECM-PTL is engineered for deployment in unstable or rigorous environments. It operates with a wide-range DC input of 12V to 24V and includes options for extended temperature ranges to maintain performance in extreme thermal conditions. Security and system monitoring are addressed through the inclusion of a Trusted Platform Module (TPM) 2.0, a hardware watchdog timer, and integrated hardware monitoring features. These components ensure the system remains stable and secure during long-term operation in smart manufacturing and industrial control scenarios.
