Why APPPCB
Every layer.
Working together.
A connected product needs more than three separate deliverables. We align interfaces early and validate the complete journey, from a sensor reading on the board to the result in your app.
One coordinated engineering workflowHardware, firmware and app milestones aligned around your product requirements.
System-level validationDevice pairing, commands, data and update flows tested together.
Clear production & development handoverAgree source code, design files, BOM and test documentation in your project scope.
A clearer way forward
From concept to
connected product.
A clear development path, with scope, deliverables and review points agreed before the build.
01
Define the product
Share the use case, hardware needs, connectivity, app features and target market.
02
Design the full stack
Align schematics, firmware architecture, device protocols and app UX.
03
Prototype & integrate
Bring up the board, develop firmware and apps, then test the complete system.
04
Prepare for launch
Prepare production files, software handover and export delivery to your agreed scope.

What files do you need to get started?+
Start with a product brief. For PCB work, share schematics, Gerbers and a BOM if available. For embedded work, include the MCU and protocol requirements. For apps, describe the platforms, device connection and key user flows.
Can I start with just one service?+
Yes. We can support PCB work, embedded firmware or app development independently, or coordinate all three. We review your existing design, code and interfaces before agreeing the scope and timeline.
What will I receive at handover?+
Deliverables are agreed in the project scope. They can include PCB design and production files, BOM, firmware source, app source and builds, protocol documentation and test results. We also agree ownership and third-party licenses before development.
How do international projects work?+
We collaborate remotely with written requirements, milestone reviews and shared test results. For hardware shipments, destination, logistics, customs documents and applicable compliance requirements are confirmed in your quotation.
