From Firmware to Cloud: Full-Stack Includes the Hardware

Taking a product from STM32/ESP32 firmware and custom PCBs up through edge telemetry to a cloud dashboard — and why owning the whole stack removes finger-pointing.

In tech, “full-stack” usually means front-end to back-end software. But for embedded and IoT products, full-stack takes on a wider meaning: hardware design, firmware, edge processing, and cloud integration. At Slopey Industries, owning every layer — from the silicon up to the cloud dashboard — is what makes the system actually reliable, and it eliminates the finger-pointing that happens when those layers belong to different vendors.

The Hardware Layer

It starts with picking the right microcontroller. For a lot of our work that’s a choice between STM32 and ESP32, driven by feature set, radio needs, and availability. We design custom PCBs to the client’s requirements so the board does exactly what the product needs — no more, no less.

Firmware Development

With the board defined, we write firmware that talks directly to the hardware, manages limited resources, and handles the communication protocols. Security and determinism come first: the firmware has to behave under real-world conditions, not just on the bench.

Edge Telemetry

Next we push processing to the edge. Collecting and filtering data on-device cuts latency and bandwidth, and it keeps the system useful even when connectivity is spotty. Sensors and local logic decide what’s worth sending before anything hits the network.

Cloud Integration

Finally the data lands in a cloud dashboard so the client can monitor fleets remotely, watch trends, and act on them. The cloud side is built to be scalable, secure, and genuinely usable — a dashboard nobody reads is just an invoice.

Owning the Full Stack

When one team owns hardware through cloud, a problem has one owner. No “it’s the firmware” / “no, it’s the API” standoff. We diagnose across the boundary and fix it, because we built both sides of it.

Bottom line: Owning the entire stack, from board to cloud, is what lets us ship integrated products and fix issues fast — because there’s no seam to argue over.
