Core Competencies
Specialized engineering domains spanning embedded systems, IoT infrastructure, robotics, PCB design, and firmware development — backed by active laboratory research and production-grade prototyping capabilities.
Microcontroller-based system design, firmware development, and real-time operating system (RTOS) implementation. Proficiency in ARM Cortex, AVR, and PIC architectures.
Cloud-connected device ecosystems with edge computing, protocol implementation, and secure data transmission. Integration with AWS IoT, Azure IoT Hub, and private MQTT brokers.
Autonomous navigation systems, robotic manipulator control, and sensor fusion for mobile platforms. Integration with ROS (Robot Operating System) for advanced applications.
Multi-layer board layout with controlled impedance, signal integrity analysis, and EMI/EMC-compliant design. Boards fabricated and assembled to IPC standards.
Production embedded software: hardware abstraction layers, peripheral drivers, secure bootloaders, and over-the-air update pipelines built in C and C++.
Methodology
System specification documentation, constraint identification, feasibility assessment, and technical requirement gathering.
SPICE-level circuit modeling, component selection, power analysis, and signal integrity verification using industry-standard EDA tools.
Multi-layer board layout, impedance-controlled routing, thermal management, and design rule checking (DRC) validation.
Embedded software architecture, driver development, protocol implementation, and hardware abstraction layer (HAL) design.
Common Questions
Hexcode Plus R&D is an MSME-certified hardware engineering laboratory in Thiruvananthapuram, Kerala, founded in 2019. It designs embedded systems, IoT infrastructure, robotics platforms, custom PCBs and production firmware, taking hardware products from concept through prototype to manufacturing handoff.
Hexcode Plus operates two offices in Thiruvananthapuram (Trivandrum), Kerala, India: Comptron Arcade, Kallattumukku (695012) and South Road, Mudavanmugal, Poojappura (695001). It serves clients across India and internationally. Contact: info@hexcodeplus.com, +91 9633118080.
Five: embedded systems (ARM Cortex, STM32, ESP32, AVR, PIC), IoT infrastructure (LoRaWAN, MQTT, edge computing, AWS and Azure IoT), robotics engineering (ROS 2, SLAM, autonomous navigation), PCB design (multi-layer, controlled impedance, EMI/EMC to IPC standards) and firmware development (embedded C/C++, FreeRTOS, bootloaders, OTA).
Both. Hexcode Plus works with hardware startups taking a first product from concept to manufacturable design, and with established manufacturers retrofitting IoT monitoring onto existing equipment. Engagements range from a single subsystem to full product development.
