Microcontroller Firmware
Firmware in C, C++ and Rust for ESP32, STM32 and other platforms — on FreeRTOS or bare metal, tuned for tight power and memory budgets.

Embedded IoT Solutions
We build custom embedded and IoT solutions: microcontroller firmware, industrial devices, telemetry and remote equipment control. We take a product from a dev-board prototype to ready for series production.
About this service
What it is and how we do it
Embedded development is the software that lives inside a device: a controller, a sensor, a board, a piece of industrial equipment. We write firmware in C, C++ and Rust for ESP32 and STM32 microcontrollers, run FreeRTOS or embedded Linux on them, and connect the device to the outside world over MQTT, Modbus, CAN, RS-485 or a cellular link. The device stops being a black box: you see its state online, receive its readings, and control it remotely.
We build the other half of the system too — the server side that ingests telemetry, keeps history, renders dashboards and raises alerts. That gives you one loop: a fleet of devices, their live status, automatic responses to failures, and over-the-air (OTA) firmware updates with no site visit. That is exactly how our TechMonitor project works — round-the-clock monitoring of LED screens with an automatic reboot when a device drops off the network.
What We Offer
Our Capabilities
Industrial Protocols
Modbus, CAN, RS-485, MQTT, OPC UA and integration with existing PLC and SCADA setups — including equipment with no documentation.
Telemetry & Monitoring
Real-time readings from the field, measurement history, dashboards, online/offline status and alerts when values drift.
Remote Control & OTA
Commands to the device, automatic reboot on failure, and over-the-air firmware updates without dispatching a service crew.
Hardware/Software Integration
We work alongside your hardware engineers: choosing sensors and radio modules, on-board debugging, and diagnosing faults where silicon meets code.
Production Readiness
Test rigs, factory flashing procedures, documentation, and preparing the product for certification.
Good fit
When to talk to us
- You have equipment whose state is invisible remotely — every failure reaches you as a phone call from the customer.
- You manufacture or assemble devices and need the firmware, plus a server side to manage the fleet.
- You need equipment from different vendors — including old kit with no protocol documentation — in one system.
- Servicing means physically driving to the device, and you want remote diagnostics and OTA updates instead.
How We Work
Our Process
- 01
Requirements
We map how the device is used, its operating environment, power budget, link options and the cost ceiling per unit.
- 02
Platform Choice
We pick the microcontroller, sensors and connectivity, then cost the unit and leave headroom for features that come later.
- 03
Prototype
A working sample on a dev board, proving the core assumption before you invest in custom hardware.
- 04
Firmware & Server
We build the firmware and the server side around one exchange protocol, with dashboards and alerting.
- 05
Field Trials
Testing in real conditions: link quality, interference, temperature, and behaviour on dropouts and power spikes.
- 06
Production & Support
We hand the product to manufacturing, ship OTA updates, and keep watching the fleet after launch.

Questions about this service
Do you design the device itself, or only the software?
Our core responsibility is the software: the device firmware and the server system for telemetry and control. The circuit design and board manufacturing stay with your producer or contractor, and we work alongside them — advising on the microcontroller, sensors and radio module so the hardware does not have to be redone to suit the software.
Can you connect equipment that has no protocol documentation?
Yes, that comes up often. We capture and analyse the device's traffic, reconstruct the exchange logic and build a compatible driver. We do the same for legacy systems whose vendor no longer supports integration.
What happens if a device loses its internet connection?
Firmware is designed for an unreliable link: readings are buffered in device memory and pushed to the server once the connection returns, while the device keeps performing its main function autonomously. On a long outage it can reset its own link or fail over to a backup channel.
How long does an IoT project take?
A dev-board prototype is usually ready in 4–8 weeks, and the full path to production readiness takes 4 to 8 months — mostly because of field trials, which cannot be rushed: the device has to be proven in real conditions, including link and power interruptions.
