Common Questions

Engineering & Consulting FAQ

Answers to common questions about hardware deliverables, supported microcontrollers, and collaboration workflow.

What microcontroller families and wireless platforms do you specialize in? +

I specialize in Nordic Semiconductor (nRF52832, nRF52840, nRF5340 with BLE and BLE Mesh), STMicroelectronics STM32 (ARM Cortex-M0+/M3/M4/M7), Espressif (ESP32, ESP32-S3, ESP8266), and Microchip AVR/PIC microcontrollers. Firmware is engineered in bare-metal C/C++, FreeRTOS, or Zephyr RTOS with ultra-low power optimization.

What deliverables are included with PCB design services? +

Every hardware project includes complete Altium Designer or KiCad source project files, schematics in PDF format, production-ready multi-layer Gerbers (RS-274X/ODB++), Excellon drill files, a Bill of Materials (BOM) with manufacturer part numbers and active distributor links, pick-and-place centroid files, and 3D STEP models for mechanical enclosure verification.

Can you build desktop or companion apps for hardware devices? +

Yes. I build native macOS companion applications using Swift 6 and SwiftUI. These communicate with devices over Bluetooth Low Energy (CoreBluetooth) or serial USB, providing live telemetry, d'Arsonval analog/digital gauges, statistics, and RFC 4180 CSV logging for test benches and production validation.

Who owns the intellectual property (IP) and design files? +

You retain 100% full intellectual property ownership. All schematics, PCB layout files, firmware source code, documentation, and CAD models are handed over upon project milestone completion. Standard non-disclosure agreements (NDAs) are signed before confidential project discussions.

Ready to build something amazing?

Whether you need firmware development, PCB design, or a full system architecture, I'm available for freelance projects.
