One Group, Four Doors: How the inteRFace R&D Family Fits Together

If you found us through a search engine, there is a decent chance you landed on the wrong site first — and that is partly our fault. Search for embedded courses and you might hit our consulting homepage. Search for a chip design course and you might end up at CHIPS, our kids program, because the names collide. So this post is the map. inteRFace R&D is one small Silicon Valley engineering group with four public doors, and each door is built for a different person. Here is what each one is for, who should walk through it, and why a consulting firm bothers running an education arm and product incubations in the first place.

Why a consulting firm runs an education arm at all

The honest answer is that the education work started as an internal discipline, not a business plan. Consulting has a known failure mode: you get very good at the three platforms your current clients use and quietly fall behind on everything else. Recording a course is the opposite pressure. You cannot record forty minutes on Linux device drivers or STM32 DMA with a vague understanding — the camera finds every gap. So we started teaching partly to force ourselves to keep first-principles knowledge fresh, and partly because the material already existed: the same explanations we give clients in design reviews, cleaned up and structured. The kids program and the product incubation came later, for different reasons, but the pattern held. Every branch of the group exists because it makes the engineering core better, not because a strategy deck called for a portfolio.

inteRFace R&D — the door for companies building a product

The parent brand at https://interfacernd.com is the consultancy, and it is for companies — founders with a validated idea and no hardware team, or engineering leaders who need senior bandwidth without a six-month hiring cycle. One team carries a product from schematic to production: PCB design, embedded firmware from bare-metal to RTOS to Linux, industrial design, in-house prototyping on our own 3D printers and CNC, DFM, FCC/CE pre-work, and production ramp, plus the companion app and cloud when the product needs one. The commercial terms are deliberately plain: priced in engineering hours, a written quote with phases before any work starts, no equity ever, the client owns 100% of the IP, and the founder is on every project. If you are building a physical product for sale, this is your door. The other three doors are for people, not companies.

Embedded Academy — the door for working engineers

https://academy.interfacernd.com is recorded, self-paced courses in embedded Linux, STM32, and ESP32, built for engineers who already have a job and want to level up without a bootcamp schedule. One clarification, since search engines send people here for chip design courses: we do not teach RTL, ASIC flows, or silicon layout. Our courses live one layer up — the software that runs on the chips. Device trees, bootloaders, drivers, RTOS internals, peripheral configuration on real silicon. That layer is where most embedded jobs actually are, and it is the layer our consulting work lives in, which is exactly why the courses exist. The curriculum is the same material we use in client design reviews, and the skills the courses teach are the skills we hire for.

ArduinoStudio — the door for makers and fast prototypes

https://arduinostudio.com is our product incubation: an AI-powered project creator for real Arduino hardware. You describe what you want to build, and it generates the three things every hardware project needs as one consistent set — the Logic (firmware that runs on the board), the App (a companion interface to control it), and the Wiring (a diagram showing exactly how to connect the components). Generating them together is the point. Anyone who has followed a tutorial where the code says pin 9 and the diagram shows pin 6 knows why. It is built for makers, students, and engineers who want a working proof of concept in an evening instead of a weekend. It also keeps us honest: a consultancy that only advises clients on shipping never feels its own advice. Running our own product means we do.

CHIPS — the door for kids, and the longest pipeline we run

https://chips.interfacernd.com is hands-on STEM for kids in the Bay Area. Small groups, real components, real tools — circuits you can hold, not simulations on a tablet. If you searched for Arduino for kids, this is the door. There is no revenue logic behind CHIPS and no funnel math that justifies it. The reasoning is longer than a business plan: the engineers who will build hardware in 2040 are eight years old right now, and most of them have never held a resistor. Someone put a soldering iron in our hands once. CHIPS is us returning the favor, and it has a side effect we did not plan for — explaining a circuit to a nine-year-old is the most brutal clarity test an engineer can face. Our team comes back from those sessions better at explaining things to clients.

How the four doors feed each other

None of these branches is a marketing funnel for the others. Each one stands on its own. But they are connected in ways that compound:

• Teaching forces clarity. An engineer who can explain interrupt latency to a camera, or a circuit to a fourth-grader, understands it better than one who can only implement it.
• Courses keep the consulting sharp. Producing Academy material forces us to stay current on toolchains and platforms beyond whatever this quarter's client projects happen to use.
• The Academy doubles as our hiring bar. The curriculum is a public statement of what we expect a senior embedded engineer to know, and course-driven skills are what we screen for.
• ArduinoStudio keeps us honest about shipping. Advising clients on product decisions lands differently when we make the same decisions on our own product every week.
• CHIPS builds the long pipeline — and reminds a team that spends its days on DFM checklists and certification paperwork why hardware was fun in the first place.

Which door is yours?

If you skimmed everything above, here is the routing table:

• You are a company building a hardware product and need a senior team — https://interfacernd.com
• You are a working engineer leveling up on embedded Linux, STM32, or ESP32 — https://academy.interfacernd.com
• You are a maker or engineer who wants a working Arduino prototype fast — https://arduinostudio.com
• You have a kid in the Bay Area who likes taking things apart — https://chips.interfacernd.com

And if you are not sure — a founder who also wants to understand the firmware, an engineer with a product idea, a parent who is also an engineering manager — that overlap is normal here. Most of us walked through more than one of these doors ourselves. Write to us through https://interfacernd.com/#contact and we will point you at the right one. No pitch attached; routing people correctly is cheaper than confusing them.
