I build firmware that works — reliably, efficiently, and at scale. I'm the founder of Adben Industries Pvt. Ltd., a Kolkata-based embedded systems company with a dedicated team of hardware and firmware engineers. We've delivered production-grade embedded solutions to clients across the globe — spanning medical devices, industrial IoT, and wireless products. Microcontroller Platforms: STM32 (H/F/G/L), Nordic nRF51/52/54/9160, Silicon Labs EFR32, ESP32, NXP LPC & Kinetis, Microchip PIC16/dsPIC33/PIC32, TI Tiva C & SimpleLink, Dialog DA16200 — bare-metal and RTOS (FreeRTOS, ThreadX, Zephyr). Embedded Linux on Raspberry Pi, STM32MP1, i.MX6/7/8. What makes us different: 🔬 Deep debugging — J-Link, J-Trace, IAR I-jet, SystemView, Ozone, ITM, CoreSight. We trace, not guess. ⚡ Ultra-low-power expertise — including Silicon Labs SiWx917, a Wi-Fi SoC maintaining live connectivity at ~25 µA. A genuine game-changer for battery-powered IoT. 📡 Full wireless stack — BLE, Wi-Fi, LoRaWAN, NB-IoT, Zigbee, Sub-GHz RF, GPS, 3G/4G LTE. 🔌 Peripheral drivers — UART, SPI, I2C, I3C, I2S (audio), CAN, DMA, ADC, DCMI, parallel display, and more. 🖥️ FPGA development — high-performance data acquisition systems for deterministic, high-speed parallel data capture. 🧠 On-device AI/ML — CNN deployment using NXP eIQ Neutron and Arm Ethos-U55. 🏥 Medical device firmware — safety, reliability, and compliance are non-negotiable. 🛠️ Sensor integration — SpO2, PPG heart rate, IMU, LiDAR, radar, CO/CO2, environmental, and more. In-House Electronics Lab: 500 MHz oscilloscope, 7.5 GHz spectrum analyzer, VNA, SMU, bidirectional power supplies, load testers, professional rework stations, and a full suite of hardware debuggers. We validate on real hardware — every time. If you need an embedded engineering team that can own a project from architecture to production, let's talk.
