Skilled PCB Designer for Production-Ready Board
Budget: ₹400 – ₹750 INR
I am looking for an experienced PCB designer to design a production-ready PCB.
-Overview
The PCB will:
Accept a plug-in S3-N16R8 board
Include 4 × 8-pin high-current board connectors
Be powered via USB-C Power Delivery
Provide regulated 5V output
Support powering an ESP32
Support a possible 15W wireless charger
Be fully engineered (power design, protection, layout, manufacturing ready)
-Connector Requirement (Important)
Each of the 4 ports must:
Be an 8-pin board-mounted connector
Allow connection using a female cable plug
Be locking and secure (not Dupont type)
Support high current safely (minimum 5A total system capacity)
Designer should recommend a compact but high-current connector system, such as:
Molex Micro-Fit 3.0 (2x4)
JST-VH (2x4)
Or equivalent professional connector
-Not acceptable:
JST-XH
Dupont headers
Low current connectors
- Port Pin Definition
For each 8-pin port:
Pin 1 → 5V (VCC)
Pin 8 → GND
Pins 2–7 → Signal lines (GPIO / data from ESP32)
All ports share:
Common regulated 5V rail
Common GND plane
- Power System Requirements
Input:
USB-C PD input
Must accept standard USB-C chargers
Should negotiate 9V or 12V PD profile (designer to recommend best option)
Regulation:
High-efficiency buck converter
Stable 5V output
Minimum 5A capability
Thermal management considered
Protection:
Overcurrent protection
Short-circuit protection
Input protection
Per-port protection preferred if possible
-Load Requirements
Board must support:
5V LED strips
General 5V accessories
One port possibly powering:
15W wireless charger (~3A at 5V)
Total expected load:
Around 20W minimum capability
Designer must calculate:
Proper trace widths
Copper thickness
Power planes
Thermal performance
- Deliverables
Complete schematic
PCB layout
BOM (LCSC preferred)
Gerber files
Pick & Place file
3D renders
JLCPCB-ready manufacturing files
Documentation
-Expectations
Compact PCB
Clean professional routing
Proper ground plane
Power plane separation
Designed for manufacturability
Ready for small-batch production
Designer must have prior experience designing:
USB-C PD power systems
5V 3A–5A DC power distribution
ESP32-based boards
