Explore our portfolio of successful electronic design projects. Each project showcases our expertise in different areas of electronic engineering, from precision analog measurements to advanced wireless solutions.
Precision Analog Measurement
An industrial high-precision dual-channel analog measurement board. The circuit can be dynamically configured with different gains and also for either voltage (0-30V) or current (4-20mA) measurement. The entire circuit is also galvanically isolated from the rest of the system. The analog inputs include protection for over-voltage and external transients.
Ultrasonic Level Sensor
As part of a high precision dispensing device, a high frequency dual transducer ultrasonic level sensor was developed. The particular requirement for this project was that the sensor had to be able to measure down to a very short distance of around 10mm from the sensor. This was achieved through the use of high frequency transducers and innovative signal processing.
BLE Sensor
A BLE sensor was designed for an activity monitoring application, based on the Nordic nRF52832 SoC. The design included an onboard PCB trace antenna, IMU, storage memory, and an interface to an array of analog sensors that were periodically scanned and transmitted over BLE. The design was powered by a coin cell battery.
Custom Boost Converter
A high power boost converter switching power supply was designed with selectable constant current or constant voltage operation and other firmware control options for a specific application. A bent aluminum sheet heatsink was also designed for this application to ensure the full design would fit within a very tight space.
High Power Solar Converter
A high power switching converter for a solar-driven pump application with backup Li-Ion battery and MPPT control. The design also included cellular connectivity for remote monitoring and control.
IoT Crop Sensor
As part of an IoT monitoring system for crop management, an ultra-low power control board was designed. The board includes a solar power input with MPPT control for charging a small LiPo battery. The control board is based on an ST STM32L433 ARM Cortex microcontroller operating in a very low power mode such that it periodically wakes up to read a number of sensors and transmit relevant data over an IoT cellular network (modem not shown).
PoE Asset Monitor
A PoE-powered asset monitor for building management systems. The device detects and tracks wireless tags on various movable assets for quick location and inventory management. The system includes a PoE interface for power and data, a BLE interface for tag detection, and onboard processing for data logging and network communication.
Cascaded High-Voltage Inverter
A highly compact cascaded inverter capable of generating accurate, variable frequency sinusoidal waveforms at high voltages up to 2kV, while powered from a low-voltage DC source. The inverter is designed to be expandible through a modular approach and optimized for tight space and high efficiency.
Flex-PCB Heater Strip
As part of a battery management system that required operation in very low temperature conditions, this flex heater was developed to be wrapped around and through the system to warm it up to the correct temperature. The heater includes a heating trace on one side and a heat spreader on the other side to ensure even heating of the system. The heater was then controlled using a built-in PID controller by the system itself.
