About this Gig
I provide professional custom PCB design for IoT devices, wireless products, embedded systems, RF electronics, and electronic prototypes from schematic design through manufacturing-ready files.
My services include LoRa PCB, LoRaWAN hardware, ESP32 PCB, STM32 PCB, nRF52/nRF53/nRF54 PCB, RF PCB layout, multilayer PCB design, antenna routing, power management, and custom circuit board development.
I can help with:
- Custom PCB and circuit layout
- Schematic capture and PCB layout
- LoRa and LoRaWAN hardware
- ESP32, STM32 and nRF development boards
- RF PCB design and RF routing
- 2-layer, 4-layer, 6-layer and multilayer PCB
- Wireless and IoT device hardware
- Antenna feed and matching layout
- USB, SPI, I2C, UART, CAN, Ethernet and wireless interfaces
- Power supply, battery and charging circuits
- Component selection and footprint
- BOM, component sourcing and CPL files
- 3D PCB modeling and STEP files
- Gerber, drill and PCB fabrication files
- PCB assembly and manufacturing preparation
- DRC/ERC checks and design verification
I use Altium Designer, KiCad, EasyEDA, LTspice, Proteus and CST Studio Suite for PCB design, simulation, RF layout and verification.

FAQ
Can you work from a block diagram or only from complete schematics?
I can work from a block diagram, written requirements, reference board, datasheet, or an existing schematic and develop the design from there.
Can you match a specific PCB size or enclosure?
Yes. Provide the required board dimensions, mounting holes, connector locations, enclosure constraints, or mechanical drawings and I will design around them.
Can you use specific components that I have already selected?
Yes. Send your preferred part numbers or BOM and I can incorporate them while checking footprints, availability, and suitable alternatives where necessary.
Can you work with an existing PCB that needs correction or redesign?
Yes. I can review the existing files, identify layout or schematic issues, and update the design according to your requirements.
Will the design be ready to send to a PCB manufacturer?
Yes, I provide the required fabrication and assembly files after completing the necessary design checks.
Can you design around a specific LoRa, ESP32, STM32, or nRF module?
Yes. You can provide the exact module, chipset, or reference design and I can build the surrounding circuitry and PCB layout around it.
Can you help reduce the PCB size or component count?
Yes. I can optimize component placement, routing, layer usage, and circuit organization based on your size, cost, and performance requirements.
Can you prepare files for PCB assembly as well as fabrication?
Yes. Assembly documentation such as BOM and Pick-and-Place/CPL files can be included when required.
