About this Gig
Please contact me before placing an order :-))
I will turn your electronics project idea into a fully functional prototype, from concept to production-ready hardware.
I can design boards using ESP32, ESP8266, STM32, ATmega, power supplies, BMS, charging circuits, sensors, actuators, connectors, and RF components.
My Expertise Include:
- PCB Design by using KiCAD, EasyEDA and Altium Designer
- ESP32, ESP8266, STM32, ATmega microcontrollers
- SPI, I2C, UART, RS232, USB protocols
- RF design for 2.4GHz, Wi-Fi, Bluetooth, LoRa, NFC, RFID UHF
- Low power / battery powered boards
- Signal Integrity and EMI
- Stack-up building
- Controlled impedance calculation
- Differential pairs and transmission line routing
- Matching network design
- Arduino and STM32CubeIDE
- Embedded Programming
- Antenna Design and Tuning with HFSS
- Microstrip Antenna / SMT Antenna solutions
Manufacturing Ready Deliverables:
- Schematic Files (Editable source + PDF)
- Editable KiCad, EasyEDA, Altium project
- Fabrication-ready outputs (Gerber & Excellon Drill Files)
- Bill of Materials (BOM)
- Pick-and-Place / CPL Files
- 3D PCB Model
- Fabrication & Assembly Drawings
- Design Verification (DRC/ERC) Reports
- Basic Firmware / Test Code
FAQ
Should I contact you before placing an order?
Yes I highly recommend to contact me and send your requirements, existing files, components, and specifications first so I can review the scope and can check that am I able to do it or not.
Can you develop my electronics project from concept to prototype?
Yes. I can help with component selection, schematic design, PCB layout, prototype preparation, testing, and manufacturing-ready files.
Can you design a custom PCB based on my requirements?
Yes. I can design 2-layer, 4-layer, and multilayer PCBs based on your schematic, specifications, or project concept.
Which microcontrollers do you work with?
I work with ESP32, ESP8266, STM32, ATmega, and Arduino platforms, including their required peripherals and interfaces.
Can you select suitable components for my project?
Yes. I can help select components based on functionality, availability, performance, power requirements, and project constraints.
Can you design power, battery, and charging circuits?
Yes. I can design power supplies, battery-powered circuits, charging circuits, protection, and BMS-related hardware as required.
Can you handle wireless and RF PCB designs?
Yes. I can work with Wi-Fi, Bluetooth, LoRa, NFC, RFID, and 2.4 GHz RF designs, including antenna and RF routing considerations.
Can you handle high-speed or signal-integrity requirements?
Yes. I can consider PCB stack-up, controlled impedance, differential pairs, transmission-line routing, signal integrity, and EMI requirements.
What manufacturing files will I receive?
Depending on the project, I can provide schematic, editable PCB source files, Gerbers, Excellon drill files, BOM, Pick-and-Place/CPL, 3D PCB model, fabrication drawings, and DRC/ERC reports.
Can you provide firmware for testing the prototype?
Yes. I can develop basic embedded programming and test firmware for hardware bring-up, peripheral testing, sensors, communication interfaces, and validation.
