Trusted by Fortune 1000 Clients and Funded Startups

We deliver for startups and enterprise clients alike, with ISO-compliant processes, published case studies, and post-launch support. Our certified teams have extensive experience with STM32/ESP32, React, Node.js, and large-scale BLE systems, ensuring your investment delivers measurable ROI.

How is a microcontroller CPU different from a regular CPU in a business application?
A microcontroller CPU is designed for embedded tasks—powering devices like wearables, smart sensors, or industrial equipment—where low power and dedicated control are critical. In contrast, standard CPUs typically run full operating systems for servers or PCs. By choosing the right microcontroller, businesses achieve lower costs, greater reliability, and tailored product performance for IoT and connected devices.
What should I consider when choosing an embedded microcontroller for my IoT product?
Key factors are connectivity (e.g., Bluetooth, Wi-Fi), scalability, energy efficiency, and ease of integration. At bluesBrackets, we support businesses in selecting the most suitable programmable microcontroller, optimizing for both technical feasibility and long-term ROI, whether you’re in healthcare, smart home, or industrial sectors.
How quickly can you develop a cross-platform mobile MVP or embedded prototype?
Our rapid prototyping process—combining React Native and proven microcontroller platforms like STM32 or ESP32—means we can deliver functional MVPs and hardware prototypes in as little as 2 to 12 weeks, depending on complexity. This approach gets you market feedback faster while containing development costs.
What post-launch support and project visibility do you provide?
We offer transparent project management, regular milestone demos, clear communication, and ongoing post-launch support. bluesBrackets ensures that every client stays informed, can request rapid feature changes, and achieves long-term product scalability.
How have your solutions helped clients achieve business results?
Our solutions help clients achieve concrete business goals through process optimization, operational cost reduction, and faster innovation deployment. We combine embedded technology expertise with a modern software development approach, resulting in measurable business benefits - from increased operational efficiency to reduced time-to-market for new products.
