Medical Data Secure Uplink Kit — Encrypt Vitals at Source with Portenta C33 TrustZone

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit empowers you to construct a secure medical data uplink — a device that captures patient vitals (SpO2, heart rate, ECG) and encrypts them on the microcontroller with TrustZone, then transmits over TLS with a verifiable audit trail. The project mirrors real-world medical IoT architectures where data encryption must happen at the edge, not in the cloud. It’s a blueprint for GDPR-conscious health IoT, turning a bench project into a professional portfolio piece.

What You'll Build

A self-contained biomedical monitor. It reads blood oxygen and ECG from MAX30102 and AD8232, processes on Portenta C33’s dual-core with TrustZone isolation, encrypts the data, timestamps with DS3231, stores locally on microSD, and sends via TLS-secured MQTT to a cloud broker. Every transaction is logged, creating an auditable chain of custody for patient data.

What You'll Learn

• Implement hardware-isolated encryption using ARM TrustZone on Portenta C33 to protect medical data.
• Acquire SpO2, heart rate, and ECG signals with proper conditioning.
• Build a TLS-secure MQTT client for encrypted payloads with audit trail logging.
• Integrate RTC, buck converter, and enclosure for a portable device.
