FAQ
1. What do I need to provide to get started?
You can start with a simple idea, block diagram, or even a rough sketch. If you already have requirements like preferred microcontroller, interfaces, or dimensions, sharing those helps accelerate the process.
2. Will I receive all the files needed for manufacturing?
Yes, I will provide complete production-ready deliverables, including: Schematic and PCB layout files BOM (Bill of Materials) Gerber and Drill files Pick-and-place files 3D step files (if needed)
3. Can you help me reduce cost and optimize component selection?
Absolutely! I choose components based on your budget and availability (considering lead times and supply chain). I also suggest cost-effective alternatives or integrated solutions when possible.
4. Do you also write firmware for the board?
Yes, I can provide basic firmware for initial board testing—such as GPIO, sensor interfacing, UART communication, etc.—using platforms like Arduino and STM32CubeIDE.
5. Can you design RF circuits or antennas for wireless communication?
Yes, I have experience designing for Wi-Fi, Bluetooth, LoRa, NFC, and RFID UHF. I also offer microstrip or SMT antenna integration and can assist with antenna tuning and matching network design.

I chose Maryam to undertake my project because she struck me as a very capable and talented engineer, and she has proven that is true. My correspondence has not been with Maryam directly, and I understand that culturally a woman can't talk to a man, but having a go between has made "attention to detail"...
