Healthcare is undergoing a digital transformation. From portable diagnostic tools to connected patient monitors and AI-assisted imaging systems, medical technology is advancing faster than ever. At the heart of these intelligent devices lies embedded computing—where System on Modules (SoMs) play a critical role.
At Calixto Systems, we design and manufacture production-ready SoMs that are ideal for building reliable, high-performance, and regulatory-compliant medical devices. In this blog, we explore how SoMs are shaping the future of healthcare electronics.
What Is a System on Module (SoM)?
A System on Module is a compact, modular computing unit that contains:
A powerful processor (e.g., ARM Cortex-A7/A8/A53/A55/A72)
RAM and flash memory
Power management and essential I/O interfaces
Calixto’s SoMs are designed to be integrated with custom carrier boards, allowing medical device developers to accelerate development while retaining full control over form factor and I/O.
Why SoMs Are Ideal for Medical Devices
Faster Development, Shorter Certifications
Designing a full processor board from scratch increases development time and regulatory complexity. SoMs reduce that burden by offering a pre-tested, stable compute platform—allowing teams to focus on application-specific design and compliance.
Compact and Power Efficient
Medical devices often need to be compact, portable, or even wearable. Our TINY and STAMP SoM families offer powerful compute in small footprints with ultra-low power consumption—perfect for battery-operated health devices.
Long-Term Availability
Calixto’s SoMs are built on processors with 10+ years of lifecycle support, ensuring your device remains maintainable and serviceable long after launch.
Real-Time Capabilities
Some medical applications demand low latency and deterministic response. SoMs based on TI Sitara (e.g., AM335x) with PRU support or NXP platforms with real-time features offer the timing precision required for critical measurements and controls.
High Reliability and Safety
Calixto SoMs are engineered with industrial-grade components, EMI/ESD resilience, and rigorous validation—crucial for meeting IEC/EN medical safety standards.
Use Cases: SoMs in Modern Medical Devices
Patient Monitoring Systems
Track vital signs such as heart rate, SpO₂, temperature, and ECG using a SoM-based platform that interfaces with analog front ends, performs real-time processing, and connects to hospital networks or cloud services.
Diagnostic Devices
SoMs enable handheld diagnostic tools like glucose meters, blood analyzers, or portable ultrasound systems with edge processing, secure data storage, and user-friendly interfaces.
Infusion and Drug Delivery Systems
Precision control, safety monitoring, and touch-based interfaces are all made possible using SoMs, ensuring dosage accuracy and patient safety.
Lab Equipment and Analyzers
Whether it’s centrifuges, PCR machines, or spectrometers, SoMs provide reliable control logic, data logging, and connectivity for centralized monitoring.
Rehabilitation and Assistive Devices
SoMs power motion control, sensor fusion, and feedback systems for prosthetics, exoskeletons, and smart rehabilitation equipment.
Build Smarter Medical Devices—Faster
Medical innovation is as much about speed to market as it is about device accuracy and reliability. With Calixto’s SoMs, you can drastically reduce engineering effort while gaining a scalable, production-ready foundation for your next medical breakthrough.
