Firmware Built for Manufacturing, Stability, and Scale

We build embedded firmware that is predictable in the field and easy to manufacture: clean architecture, robust drivers, secure connectivity, and structured testing. From early prototypes to production handover, POLR supports firmware development for IoT, sensor products, and connected devices for teams across Europe and beyond.

Coding

​We build production-ready embedded firmware for IoT and connected devices—covering board bring-up, peripheral drivers, RTOS workflows, low-power optimization, secure connectivity (Wi-Fi/BLE/LTE), and factory test modes. From early prototypes to manufacturing handover, POLR supports international teams delivering stable, maintainable firmware at scale.

What we do

​​​

  • Firmware architecture & board bring-up (boot, peripherals, stability)

  • Driver development (I2C, SPI, UART, ADC, PWM, GPIO)

  • RTOS-based systems (task scheduling, state machines, reliability)

  • Connectivity & networking (Wi-Fi, BLE, LTE/NB-IoT, GNSS, MQTT/HTTP as needed)

  • Low-power optimization (sleep modes, wake sources, power profiling)

  • Security basics (secure provisioning, key storage, update safety)

  • OTA updates & device lifecycle (versioning, rollback, configuration)

  • Testing & validation (logs, automated tests where applicable, fault handling)

  • Manufacturing test support (factory mode, calibration routines, serial IDs)

  • Documentation & production handover (build steps, flashing tools, release notes)

​

​

Platforms we support: ESP32 (ESP-IDF), STM32 (HAL/LL), Nordic nRF52/nRF53 (nRF Connect SDK/Zephyr), Raspberry Pi / Orange Pi (Linux), and other ARM-based embedded Linux SBCs, plus common wireless and IoT modules (Wi-Fi, BLE, LTE/NB-IoT, GNSS, LoRa) depending on the product.
