Embedded engineering & consultancy
Firmware that crashes in the field. An architecture that won't scale to the next product. A deadline that's closer than the finish line. Squarrot helps hardware teams design, debug and ship reliable embedded systems — with direct, engineer-to-engineer advice.
At home in
Services
From a single architecture review to hands-on firmware work. Pick what fits — we'll tell you honestly if you don't need us.
Choosing an MCU, an RTOS or a connectivity stack is a decision you'll live with for years. We help you make it with confidence: requirements, trade-offs, a clear architecture and a roadmap your team can execute.
A fresh pair of expert eyes on your firmware. You get a clear report with prioritised findings — reliability, safety, memory, timing and maintainability.
Random resets, hard faults, race conditions, that one bug that only shows up on Tuesdays. We dig in with the debugger and the scope until it's found and fixed.
Drivers, BSPs, RTOS applications, bootloaders and OTA updates. Clean, tested and documented C/C++ that your team can maintain after we're gone.
First boards on the bench? We get peripherals talking, validate your design and feed findings back to the hardware team before the next spin.
BLE, Wi-Fi, CAN, Modbus, MQTT and friends. Robust communication between your device, your gateway and your cloud.
Battery life measured in weeks instead of years? We profile, tune sleep modes and rethink duty cycles until the numbers add up.
Unit tests on the host, hardware-in-the-loop, automated builds. So every release is less exciting — in the best possible way.
Why Squarrot
No sales team, no layers of project managers. When you work with Squarrot, you talk directly to the engineer who does the work.
You explain the problem once, to the person solving it. No translation layers, no lost context.
A small team means short lines. We can usually start within days, not months.
If an off-the-shelf module does the job, we'll tell you. We'd rather save you money than bill you hours.
You own every line of code and every document. Everything is handed over so your team can carry on without us.
Fixed-scope proposals where possible, so you know what you get and what it costs before we start.
Readable code, sensible architecture and documentation that is actually useful. Firmware that survives its second year.
How we work
A free, no-strings 30-minute call. You tell us what's going on; we tell you honestly whether and how we can help.
Under NDA, we look at your requirements, schematics or code to understand the real problem — not just the symptoms.
A concrete plan with scope, deliverables, timeline and price. No surprises.
We get to work, with short feedback loops and regular demos on real hardware.
Code, documentation and a walkthrough for your team. Optional support afterwards.
1 – 5 days
Architecture review, code audit or a technical second opinion. Ends with a clear written report and recommendations.
Fixed scope
A well-defined piece of work — a driver, a bootloader, a bring-up, a bug hunt — delivered end to end.
Ongoing
A set number of days per month. Your on-call embedded expert for questions, reviews and development.
About
Because we like getting to the root of things — and because engineering doesn't have to be boring. Squarrot is a young, independent embedded consultancy from the Netherlands, founded by an embedded engineer who enjoys nothing more than a tricky problem, a logic analyser and a cup of coffee.
We work with start-ups building their first connected product, and with established companies that need extra embedded expertise for a while. Remote wherever it makes sense, on-site whenever the hardware asks for it.
Serious engineering. Slightly silly name.
FAQ
Probably not. A one-day code review or a single tricky bug is a perfectly good reason to get in touch.
Yes, happily — before you share any details about your product.
Both. Most advice and development works fine remotely. For bring-up and hardware debugging we're happy to come by, or you can ship us a board.
You do. All source code, documentation and intellectual property created for your project are yours.
Absolutely — that's often the best setup. We slot into your repo, your tools and your way of working.
It depends on the scope. After the free intro call you'll get a clear proposal with a fixed price or a day rate, so you always know where you stand.
