Controller for a Medical Device
This project involved designing a low-power driver board for a portable wireless spirometer. The board’s primary function is to sample pressure data at precise intervals and transmit it via Bluetooth 5.x to a paired device.
Multilayer PCB was designed with controlled impedance. The board features a high level of integration, including: a dual-core microcontroller (one core for user applications, one for the radio stack), a differential pressure sensor, Li-Ion battery management, an accelerometer, a barometer.
Always-on firmware created in C, leveraging the RTOS-style scheduler, achieves a standby current draw of just 6 μA. User interaction requires no buttons or switches – taps on the enclosure are detected and processed by an on-board accelerometer.

Real-time IoT Vehicle Diagnostics Platform
For this project, an always-connected telemetry unit was developed to integrate into a commercial lorry fleet. The compact board plugs into the vehicle’s CAN and K-Line buses and streams data to a cloud platform via a secure 4G/LTE using MQTT. By monitoring electronic control unit error codes alongside FMS metrics—such as vehicle speed, fuel level and consumption, gear position, and engine RPM—the system delivers a comprehensive picture of each lorry’s health.
In addition to vehicle diagnostics, the unit captures driver activity from the tachograph, recording driving time and mandatory breaks to ensure regulatory compliance. A built-in GNSS receiver provides live route tracking, allowing fleet managers to see vehicle locations on a map and optimize dispatch in real time. Together, these features empower operations teams to detect faults before they escalate, improve driver performance, and maximize fleet uptime—all without the need for manual intervention.

Communication System for Call Centers and Business Offices
This project consists of two main devices: a base unit and a wireless headset. They communicate using DECT wireless technology, ensuring stable and high-quality voice transmission.
The base unit supports three uplink communication channels: a computer via USB, a desk phone, and a mobile phone via Bluetooth. When the headset is worn, incoming calls from any of the connected sources can be answered directly and seamlessly.
Each incoming call is signaled audibly in the headset and visually on the base unit. The system supports up to three simultaneous active conversations, offering the ability to switch between calls, place them on hold, or terminate them individually. Additionally, the system can be used as a standard audio output device for both a PC (as a USB sound card) and a mobile phone via Bluetooth.
The headset offers an impressive continuous talk time of over 11 hours.

It features an integrated 3.3 VDC voltage regulator, enabling full utilization of the USB port’s current capability for powering external 3.3 VDC devices. An external device can also draw 5 VDC from the USB host. Alternatively, the converter may be powered from an external voltage source.
