About this Gig
Are you looking to build a rugged, high-performance IoT device that actually survives the field? Let's design it right the first time.
Welcome, I'm Mathew a professional hardware engineering specialist focusing on ESP32 IoT architectures and Semtech SX1276 LoRa / LoRaWAN hardware design. I bridge the gap between messy breadboard prototypes and market-ready, mass-manufacturable hardware.
Whether you are designing a smart agriculture sensor, an asset tracker, or an industrial smart gateway, I deliver clean schematics and highly optimized PCB layouts that prioritize signal integrity and long-range RF performance.
️ Advanced Engineering & Technical Features Included:
- True RF Optimization: 50Ω coplanar waveguide or microstrip trace calculation for the SX1276 and ESP32 RF paths. I incorporate a Pi-matching circuit layout to allow fine-tuning of your antenna system.
- Low-Power Power Trees: Specialized design patterns using ultra-low quiescent current LDOs/Buck converters, battery management ICs, and deep-sleep isolation circuitry to extend battery life for years.
- Signal Integrity & Noise Isolation
- Design for Manufacturing

FAQ
Which software do you use for the design?
I primarily use Altium Designer or KiCad (latest versions). I provide the original source files so you can make future modifications easily.
Do you design the custom antenna on the PCB or use external options?
I can design a custom PCB trace antenna (like an inverted-F antenna), implement a surface-mount ceramic chip antenna, or route the RF path to a U.FL / SMA connector for high-gain external whip antennas.
How do you guarantee the LoRa RF circuit will achieve maximum range?
I use dedicated transmission line calculator tools to match the RF trace impedance exactly to 50 ohms based on the specific PCB manufacturer's layer stack-up and dielectric constant ($E_r$). Additionally, I isolate the RF trace with solid ground shielding to prevent EMI degradation.
Do you provide firmware along with the hardware design?
This gig focuses on hardware. However, I can provide a "Basic Hardware Test" script (Arduino/ESP-IDF) to verify that the ESP32 and SX1276 are communicating correctly over SPI.
My project requires CE / FCC compliance. Can you design for this?
Yes. If you select the Premium Package, I follow strict EMC/EMI design guidelines such as solid stitching ground planes, short return paths, decoupling capacitor optimization, and proper shielding-can placement to maximize your chances of passing compliance testing on the first try
What files will I receive for manufacturing?
You will receive a complete "Production Pack" including: Gerber Files (RS-274X or X2) NC Drill Files BOM (with LCSC/DigiKey part numbers) CPL/Pick & Place File (for SMD assembly) 3D STEP Model for enclosure fitting
Do you design custom RF PCB based on my idea?
Yes, I can design your RF PCB from scratch based on your requirements, concept, or block diagram
