02 / Ertan Hardware Solutions

Designed deep.
Built to last.

We design and prototype hardware for products that need to live in the physical world — embedded systems, custom electronics, and the firmware that ties them to the software stack above.

From schematic to bring-up to first production run. Owned end-to-end with the same team that ships the software it runs on.

Capabilities

From schematic to shelf.

  • 01 — Embedded

    Firmware & RTOS

    Firmware on bare metal, FreeRTOS, or Zephyr — written for the constraints of the device, not the convenience of the framework. C, Rust, MicroPython where each fits.

    • · ARM Cortex-M / ESP / RP
    • · Zephyr · FreeRTOS · bare metal
    • · OTA, secure boot, signing

  • 02 — Prototyping

    PCB & custom boards

    Schematic capture, PCB layout, and bring-up for sensors, controllers, and connected devices. From breadboard to small-batch production with a clear BoM.

    • · KiCad & Altium-friendly
    • · 4-layer mixed-signal
    • · DfM & small-batch fab

  • 03 — Integration

    Hardware ↔ software

    Device-to-cloud pipelines, OTA update channels, and the dashboards that watch fleets in production. Built on the same edge stack as our software work.

    • · MQTT / WebSocket / HTTPS
    • · Edge gateways · ingest pipes
    • · Fleet dashboards & alerts

Who it's for

Selective by design.

Hardware engagements take real lab time and real bring-up cycles, so we book fewer of them. The right fit looks like:

Connected products
A device that needs cloud, a dashboard, and a release pipeline — not just a one-off PCB.
Industrial sensing
Telemetry, monitoring, and control gear where reliability and field-update strategy actually matter.
Pre-production prototypes
EVT/DVT-stage hardware where the spec is firm enough to commit to a layout but the firmware is still alive.
Hardware-software bridges
Existing devices that need a software layer above them — fleet management, OTA, telemetry, replacement firmware.

Engage

Selectively booking hardware engagements. Public contact channels are being set up — until then, this is where they'll appear.
