Services

From circuit board to finished product.

Every service is built to hand off cleanly to the next stage. Verified designs, complete documentation, no surprises at the factory.

The core craft

PCB Design & Layout

It starts with the board. Multi-layer schematic capture and layout in KiCad, Altium, and Eagle, from 2-layer IoT boards to dense mixed-signal and RF designs. Every board is placed and routed against a real fab stackup from the first net, so impedance, clearances, and drill sizes are correct by construction rather than fixed at the end.

Design rule checks are closed to zero errors before anything leaves the studio, and the layout ships with the exact stackup documentation your fab needs.

Embedded Firmware

Board bring-up and firmware for ESP32, STM32, nRF52, and RP2040: peripheral drivers, sensor integration, and communication stacks including UART, I²C, SPI, RS-485 Modbus, BLE, ESP-NOW, and LoRa. Because the same studio designs the hardware, the firmware is written against the actual pinout and power budget, not a guess.

Delivered as a clean source repository with build instructions and bring-up notes, ready for your team to extend.

Beyond the board

Product & Enclosure Design

3D CAD enclosures designed around the real board outline, from sheet-metal housings to consumer shells, with mounting bosses, connector cutouts, and tolerances that survive contact with an actual injection moulder or 3D printer.

Photorealistic KeyShot renders turn the design into e-commerce hero shots, packaging artwork, and investor deck imagery before a single unit exists.

Turnkey Manufacturing

Managed fabrication and assembly through JLCPCB and PCBWay with LCSC-first part selection, so the whole build stays in one supply chain. The studio handles the fab dialogue, part substitutions, and assembly queries, and you receive tested boards with tracking, not a pile of files and a factory to chase.

Design Audits & DFM

Independent review of schematics and layouts done elsewhere: ERC and DRC resolution, footprint verification against datasheets, clearance and creepage checks, and design-for-manufacture review against your chosen fab's real capabilities.

The output is an annotated report of every finding, ranked by severity, with the option to have the corrections applied directly to your project files.

Capabilities at a glance.

The numbers a hardware team checks before handing over a board. If a requirement sits outside these, ask anyway. Edge cases get an honest answer, not a stretched one.

After delivery

You own the source

Native KiCad or Altium project files transfer with the final payment, alongside every fab output. No lock-in; any engineer can pick the design up.

30-day fix window

Any ERC, DRC or fab-blocking error found within 30 days of handoff is corrected free of charge. No debate, no invoice.

Supported respins

Future revisions are quoted against the existing project files, so a v1.1 costs a fraction of the original design, not a restart.
