Engineering & firmware

Firmware and IoT devices: ESP32, Arduino, STM32. We work from your schematics or build a prototype from scratch.

We don't do PCB design or electrical work — you provide schematics. But microcontroller code, protocols (MQTT, BLE, LoRa) and cloud part — that's our territory.

What we build

Six engineering directions

01 / 1–4 weeks

ESP32 firmware

WiFi + BLE, low power, MQTT/HTTPS, OTA updates. The most popular platform.

02 / 1–2 weeks

Arduino firmware

Classic for simple tasks: sensors, relays, actuators. Low cost.

03 / 4–8 weeks

Turnkey IoT device

Firmware + cloud + monitoring dashboard. Full-cycle solution.

04 / 3–6 weeks

Telemetry & SCADA

Data collection from devices, aggregation, charts, alerts. Industrial protocols.

05 / 1–2 weeks

Prototyping

We help choose MCU, peripherals, protocols. Assemble a breadboard mock for demo.

06 / 1–3 weeks

Existing firmware update

Port to new MCU, add features, optimize power, set up OTA updates.

How we work

From schematic to OTA updates

  1. 01

    Schematic

    Receive schematic and spec. Clarify peripherals, protocols, power.

  2. 02

    Firmware

    Write code, test on dev board, prepare test rig.

  3. 03

    Testing

    On client's real board — functional tests, power measurements, stress.

  4. 04

    OTA + cloud

    Set up over-the-air update system and monitoring dashboard.

  5. 05

    Support

    30 days free. Firmware updates under support or a separate SLA.
