About this Gig
Hardware & PCB Design for nRF52 + nPM PMICs
Turn your battery-powered BLE product idea into production-ready hardware. I specialize in schematic design and PCB layout for the Nordic Semiconductor nRF52 series (nRF52832, nRF52833, nRF52840) paired with nPM PMICs (nPM1100, nPM1300, nPM2100) to deliver ultra-low-power, compact, and reliably charging hardware.
What I Offer
Hardware & PCB Design
- -->Full schematic capture and PCB layout in KiCad or Altium Designer.
- -->nPM PMIC Integration: Optimized routing for buck/LDO regulators, battery charging paths, and fuel gauge circuitry.
- -->RF Design: Antenna matching networks (trace, chip, or u.FL) and 50Ω impedance-controlled routing.
- -->Low-power component selection to achieve sub-µA standby currents.
What I Can Do For You:
- Single, Double, and Multi-layer PCB Layouts.
- Schematic capture from your hand-drawn sketches or circuit ideas.
- Mix signal routing and Impedance matching.
- BOM (Bill of Materials) with sourcing links (DigiKey, Mouser, LCSC).
Software Expertise:
- Altium Designer / KiCad
What You Will Get (Deliverables):
- Gerber Files
- NC Drill files.
- BOM with part numbers and links.
- 3D Models (STEP or OBJ) for enclosure design.
- PDF Schemat

FAQ
Which nRF52 chips do you support?
nRF52832, nRF52833, nRF52840, and modules based on them
Which PMICs do you work with?
Primarily Nordic nPM1300 (charger + fuel gauge + 2 bucks + 2 LDOs + GPIOs), plus nPM1100 and nPM2100 for primary-cell designs. I can also work with TI and Analog Devices PMICs.
Which software do you use for PCB design?
I am proficient in Altium Designer and KiCad. I can provide the source files in whichever format you prefer for your workflow.
Can you help me find the right components?
Yes! Every design includes a BOM (Bill of Materials) with active links to suppliers like DigiKey, Mouser, and LCSC to ensure parts are in stoc
What do I need to provide to get started?
To begin, I need your circuit schematic (hand-drawn is fine) or a clear description of the project requirements. If you have specific board dimensions, enclosure constraints, or a specific BOM (Bill of Materials) you'd like me to use, please include those as well.
Will my PCB be ready for manufacturing?
Yes, absolutely. I design all boards following DFM (Design for Manufacturing) and DFA (Design for Assembly) standards. You will receive a complete fabrication package, including Gerber files, NC Drill files, and Pick-and-Place files compatible with manufacturers like JLCPCB, PCBWay
What if there is a shortage of a specific component in the BOM?
Component availability is a common issue. I will double-check the current stock on DigiKey, Mouser, and LCSC during the design process. If a part is out of stock, I will suggest a pin-to-pin compatible alternative to ensure your board can be assembled immediately.
