Are you looking for Sydney electronic product design services for a unique idea not yet available on the market? Need an experienced circuit designer, mixed-signal / ADC engineer, wireless electronics engineer, control systems engineer, or professional PCB (printed circuit board) design expert to bring your innovation to life? Whether you're seeking proof-of-concept development, schematic and PCB layout review, embedded firmware support, or complete end-to-end electronic engineering services, COLETEK Electronics Design Services for Sydney delivers circuit architecture, schematic capture, PCB layout, embedded firmware, bring-up, testing, enclosure integration, and production-readiness across analog, digital, mixed-signal, power, control, wireless, and connected products.
Our team has decades of combined experience in electronic design, circuit development, prototyping, and low-to-medium volume production consulting. We also specialize in embedded firmware programming for microcontrollers, wireless SoCs, and connected products, including BLE, NFC, UWB, and cellular / GNSS IoT module integration. That includes experience with platforms such as Nordic nRF, pre-certified wireless modules such as Raytac, and cellular / GNSS module families such as SARA and other field-deployed IoT communications ecosystems. With deep experience using a variety of industry-standard and open-source EDA tools, we're well-positioned to meet the needs of startups, research labs, manufacturers, and inventors.
Our electronic design journey began in the 1990s using Protel, now known as Altium Designer. Today, while still proficient in Altium for legacy projects, we prefer open-source tools such as Lepton-EDA (formerly gEDA), pcb-rnd, KiCad, and Eagle. Using Lepton-EDA (formerly gEDA) modular structure, we’ve developed powerful internal tools with Python scripts that auto-generate footprints, BOMs, and price lists by integrating with services like Octopart and DigiKey APIs. These automations reduce project time and cost, improving efficiency for our clients.
Just a small glimpse of the custom electronics that power full-stack products we’ve built for clients.
Our Sydney custom electronics expertise covers a wide spectrum:
- 30+ years in analog and digital circuit design, prototyping and firmware development

- RF design and wireless communication protocols (WiFi, Bluetooth LE / BLE, Bluetooth Mesh, NFC, RFID, Zigbee, Thread, UWB / Ultra-Wideband, proprietary long-range RF, LTE-M / NB-IoT, Cellular, Satellite)
- Microcontroller and wireless SoC platforms: TI MSP430, ST STM32, ESP32, Nordic nRF, FPGA
- Connectivity and module ecosystems: pre-certified wireless modules, cellular / GNSS IoT modules (for example Raytac, SARA, u-blox / Trasna,, and similar vendor ecosystems), MQTT-connected devices, and mixed-radio architectures for field deployments
- Battery and power systems: PMIC, Li-Ion / Li-Po charging, wireless (inductive) charging
- Sensor integration: IMU, accelerometers, gyros, image sensors, lidar, radar, ultrasonic, IR, and industrial instrumentation sensors including current, voltage, resistance, loop-powered, and other field-sensor interfaces

- IoT device development for connected products, remote telemetry, industrial sensing, asset tracking, gateways, and specialty electronics, with wearable products supported where relevant
- UI/UX device development (e.g. LCD, TFT, touch screen, ePaper)
- Input protection and robust interface design (ESD/TVS, surge, opto, ferrite, current-limiting, polyfuse, reverse polarity, miswiring)
- Compliance-minded design for harsh environments (industrial and marine applications)
- Cost-effective embedded Linux solutions (from minimal userspace builds to full SBC platforms)
Not sure which platform fits best? Here's a simple starting point (we'll tailor it to your objectives):
- Need Linux, camera, vision, "PC-like" apps → Raspberry Pi or NVIDIA Jetson
- Need on-device AI/ML inference (vision/audio/anomaly detection) → Raspberry Pi / NVIDIA Jetson, or AI-capable MCUs (e.g. STM32-class) for lightweight models
- Need Wi-Fi/BLE built-in at low cost → ESP32
- Need BLE, NFC, Thread or Zigbee for low-power wireless products, smart locks, and wearables → Nordic nRF and similar low-power wireless platforms
- Need motor control, H-bridge drive, sensor feedback, closed-loop motion control, or hard real-time with rich peripherals → STM32 and similar real-time MCU platforms
- Need UWB, ranging, RTLS, indoor positioning, digital key, or proximity-aware product concepts → ask us about mixed-radio architectures including BLE + UWB
- Need cellular / GNSS telemetry, remote monitoring, or field-connected IoT products → ask us about cellular module integration, MQTT back-to-base systems, and device-to-cloud architectures using module families such as SARA, u-blox / Trasna,, Telit Cinterion, and similar IoT platforms
- Need "sip power for a year" sensing → MSP430 (and other ultra-low-power MCU families)
We understand that a scalable electronic product often hinges on the firmware layer. A well-selected microcontroller (MCU) or microprocessor (MPU) allows flexibility, reusability, and remote upgrades. We have extensive experience developing embedded firmware and also offer services across:
- Real-time deterministic firmware development using RTOS platforms for timing-critical embedded control, sensing, communications, and actuator/motor control
- Application software development for desktop and mobile
- GUI design for user interfaces on embedded systems and control panels
- Cross-platform development using Linux, Windows, and macOS (typically via VirtualBox or Docker)
- Full-stack web development for connected device dashboards
Our Linux-based development environment, often on Ubuntu/Debian, enables us to run robust development toolchains. Our programming skill set spans C, C++, Python, Bash, JavaScript, and more—allowing us to write firmware, APIs, backend logic, and even full-stack applications when needed.
Of course, no product is complete without physical validation. Our Sydney PCB assembly and prototyping process ensures reliable testing and debugging. We typically have PCBs fabricated overseas (China) with a 5-day turnaround, using custom stencils for precise surface-mount technology (SMT). We complete in-house reflow soldering using a reflow oven and perform through-hole and fine-pitch rework with manual soldering tools. Our team is comfortable working with 0603 components and smaller. We design for reliability in harsh environments, including marine and industrial conditions where protection and compliance considerations matter.
Electronics Design Services for Sydney and Prototyping Experience
Our CTO, Luke Cole, previously worked as a "Robotics Engineer" at Hemisphere GPS (now AgJunction), where he implemented GPS-guided auto-navigation systems for agricultural machinery including tractors and quadbikes. His background includes developing indoor tracking systems for Location Aware Technologies (433 MHz), and he has contributed to advanced R&D initiatives at NICTA, CSIRO, and the ANU Robotics Systems Lab led by Alex Zelinsky.
Lance Cole has also contributed to NICTA and led hardware development projects for military-grade systems at EOS, including the Common Remotely Operated Weapon Station (CROWS) used by the U.S. military—demonstrating our deep capability in high-reliability electronics.
We also work on low-power wireless and IoT product development for connected devices, industrial and remote sensing products, smart locks, asset tracking systems, telemetry products, control electronics, and proximity-aware systems. Wearables are one possible application area, but our capability is much broader than that. That includes BLE, NFC tap-to-pair / tap-to-unlock workflows, UWB-enabled positioning / ranging architectures, cellular / GNSS IoT module integration, and device-to-cloud systems using protocols such as MQTT. Depending on the application, this may involve platforms such as Nordic nRF, pre-certified module vendors such as Raytac, SARA / u-blox / Trasna cellular module families, Telit Cinterion, and other communications ecosystems used in remote monitoring and field deployments.
