Electronics Design Services for Rainbow

Are you looking for Rainbow electronic product design services for a unique idea not yet available on the market? Need an experienced circuit designer 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 Rainbow 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 Rainbow custom electronics expertise covers a wide spectrum:

• Analog and digital circuit design
• 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
• 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)

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 Rainbow 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.
