What We Do
We design the electronics, write the firmware and build the cloud for connected products. Hardware startups and product companies use us as one engineering team, from the first schematic to devices running in the field.
PCB Design & Prototyping
Schematic capture, PCB layout and prototype builds, designed with manufacturing in mind from the first revision.
Embedded Firmware
Production firmware for STM32 and ESP32 on FreeRTOS and Zephyr, with OTA updates and secure boot built in.
IoT Cloud Integration
Device connectivity over MQTT and CoAP to AWS IoT Core or Azure IoT Hub, with fleet monitoring and remote commands.
Embedded Linux & Gateways
Custom Yocto Linux builds for ARM boards and gateways, with the on-device application and cloud link built in.
Industrial Automation
PLC and SCADA integration, and connecting legacy industrial equipment to modern Industry 4.0 monitoring platforms.
Dashboards & Companion Apps
Web dashboards and mobile companion apps, including BLE apps that talk directly to your hardware.
Why Hardware Teams Choose Us
Connected products often slip in the gaps between the PCB designer, the firmware contractor and the cloud developer. At Freertron Systems one team owns all three, so problems get fixed where they start instead of being passed between vendors.
Our engineers have shipped custom ARM boards running Yocto Linux, ESP32 and STM32 firmware on FreeRTOS and Zephyr, BLE companion apps, and cloud backends on AWS IoT Core and Azure IoT Hub. We have delivered projects for clients in 14 countries, including the United States, Canada, the United Kingdom, Germany and Australia.
