IoT & wireless nodes
Compact boards carrying a Wi-Fi/BLE/LoRa module alongside sensors and power management.
PCB Design & Hardware Engineering
Schematic capture, multilayer PCB layout and manufacturing-ready output for connected products — designed alongside the app that controls the board, not handed off to a separate vendor after the fact.
Overview
What this service covers
Pak IT Corner designs the PCB hardware behind connected products — from a first schematic revision through a manufacturing-ready layout — alongside the mobile or web app that talks to it. Because the same team handles both sides, the board's pinout, power budget and communication interface are designed to match what the app and firmware actually need, instead of being guessed at from a datasheet after the board is already routed.
Client Problems
Problems this service solves
- A product concept exists but there's no schematic or board yet.
- An existing board has noise, thermal or reliability issues that need diagnosing and fixing.
- A design works on the bench but needs a DFM review before going to a fabricator.
- A board needs to shrink, add a wireless radio, or move from a one-off prototype toward a small or bulk production run.
- The hardware and the app that controls it are being built by separate vendors, and the integration keeps slipping.
Capabilities
What we do
- Schematic capture and multilayer PCB layout
- Power-supply and power-electronics design
- Component selection and footprint verification
- RF-aware layout for boards carrying a Wi-Fi, BLE or LoRa module
- Design-for-manufacturing (DFM) review before release
- Gerber, BOM and pick-and-place file preparation
- Board bring-up, interface testing and debugging support
- Bulk / production manufacturing coordination
Technologies
Tools & platforms
Industry-standard PCB design tools, chosen to match a project's complexity and your preferred file format. Most designs are built around ESP32, STM32 or Arduino-compatible microcontrollers as the starting reference.

Development Process
How we approach a PCB project
- 01Requirements
Confirm the board's function, interfaces, size and power constraints.
- 02Schematic
Capture the circuit and share it for review before layout starts.
- 03Layout & DFM review
Route the board and check it against the fabricator's process before release.
- 04Manufacturing handoff
Deliver Gerbers, BOM and pick-and-place files, then support bring-up and, where needed, bulk production.
Deliverables
What you receive
- Schematic files
- PCB layout files
- Gerber files
- Bill of materials (BOM)
- Pick-and-place files, where the board is going to assembly
- DFM review notes
