Electronics Design Services for Hoffman

Are you looking for Hoffman electronic product design services for a unique idea not yet available on the market? Need an experienced circuit designer, mixed-signal/ADC engineer, or professional PCB (printed circuit board) design expert to bring your innovation to life? Whether you're seeking a proof-of-concept, schematic and layout review, embedded programming support, or complete end-to-end electronic engineering services, Electronics Design Services for Hoffman has the expertise to deliver.

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 and SoCs. 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 gEDA, Lepton-EDA, pcb-rnd, KiCad, and Eagle. Using gEDA’s 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.

Our Hoffman custom electronics expertise covers a wide spectrum:

• Analog and digital circuit design
• ADC front-end design and signal conditioning (current, voltage, resistance, and mixed-signal sensing)
• RF design and wireless communication protocols (WiFi, Bluetooth, Zigbee, proprietary long-range RF)
• Microcontroller platforms: TI MSP430, ST STM32, ESP32, FPGA
• 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
• Motor and actuator control: brushed and brushless DC motors (BLDC), servos, steppers, pneumatics, hydraulics
• IoT device development and wearable electronics (e.g., LilyPad, conductive thread)
• 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 → ESP32
• Need hard real-time + rich peripherals → STM32
• 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:

• 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 Hoffman 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.
