Solving the I/O Bottleneck in Edge AI Systems
In modern Edge AI design, the "I/O Bottleneck" can be a common development hurdle. Whether you are developing an autonomous mobile robot (AMR) requiring 360-degree situational awareness or a high-end medical workstation driving multiple 4K displays, you shouldn't have to sacrifice sensor data for processing speed.
Most System-on-Modules (SoMs) lock you into a rigid configuration that forces you to compromise on your peripheral vision or display quality. The Silex EP-200Q is different. Engineered to serve as the "Central Nervous System" for I/O-intensive applications, it exposes nearly every interface of the Qualcomm QCS6490 SoC through its 500-pin LGA pads.
From Sensors to Insights: Mapping the Interface Potential
The EP-200Q provides the architectural foundation for your most complex sub-systems. By offloading AI inference to the onboard NPU, you free up the CPU to manage these high-bandwidth I/O (Input/Output) streams in real-time.

The Silex Advantage: Hardware That Adapts to Your Design
The biggest hurdle in SoM integration is often the "Fixed Pinout" trap, where the hardware manufacturer’s software doesn't match your physical layout.
As an official Qualcomm Embedded Design Center (EDC), Silex removes this risk. We don't just provide the hardware; we provide the Custom Board Support Package (BSP).
If your design requires repurposing a pre-assigned interface, such as swapping a PCIe lane for additional UARTs or GPIOs, our engineering team handles the low-level firmware architecture for you. We deliver a tailored BSP that matches your specific pinout requirements, allowing your team to focus on application-level innovation rather than kernel-level troubleshooting.
Stop Researching. Start Prototyping.
Don’t let I/O constraints or complex firmware setup stall your build. The EP-200Q Evaluation Kit is a pre-validated environment designed to bypass the "setup phase" and get you straight to development.
