Project Overview
We are looking for an experienced PCB designer to develop a compact production ready DC-DC boost converter PCB for our RC product lineup. The PCB size is fixed and must match our existing RC chassis mounting system.
The board will take input from a single 3.7V 18650 Li-ion battery and boost it to a stable constant 12V output capable of driving either BO motors or N20 motors continuously without major voltage drop under load.
This is intended for mass production, so the design must be reliable, cost optimized, manufacturable, and use easily available components.
The final design must be fully production ready and suitable for commercial manufacturing.
PCB Size and Mechanical Constraints
PCB dimensions are fixed:
60mm x 38mm
All components must be placed only on the top side of the PCB.
The placement of JST connectors and capacitor positions are fixed to match our existing RC chassis and
locking system.
Please strictly follow the provided coordinates and orientations.
PCB Functional Requirements
Main Function
Input:
Single 3.7V 18650 Li-ion battery
Output:
Stable constant 12V DC output
The board should:
• Boost 3.7V battery voltage to regulated 12V
• Maintain stable output voltage under motor load
• Power 2 DC motors continuously
• Power 2 external 3V LEDs
• Turn ON and OFF using an external switch connected through JST connector
• LEDs should turn ON immediately when PCB is powered
• Motors should start running immediately when PCB is powered
Connectors and Fixed Positions
JST Connector Details
Connector Part Number:
B2B-XH-A(LF)(SN)
All connectors are through hole type.
Capacitor Placement Constraints
We currently have locking structures in our RC chassis based on capacitor positions from our old PCB.
You may use 2 or 3 capacitors as needed for the design, but please place them within the following
locations as much as possible.
Maintaining similar capacitor size is preferred.
Capacitor Footprint:
CapacitorSMD:CPElec_8x11.9
Capacitor Part Number:
JVE16V470M8X10
Motor Specifications
The designer must properly calculate current requirements and select suitable ICs, inductors, capacitors,
and track widths.
BO Motor Specifications
Operating Voltage:
3V to 12V
No Load Current:
40mA to 180mA
Rated Speed:
60 RPM
Rated Torque:
1 kg·cm
N20 Motor Specifications
Operating Voltage:
6V to 12V
Rated Voltage:
12V
Rated Speed:
60 RPM
Stall Current:
0.75A
Rated Torque:
0.97 kg·cm
Stall Torque:
3.0 kg·cm
Design Requirements
Important Requirements
• Output voltage must remain stable at 12V under motor load
• Avoid major voltage drop during startup or load changes
• Use proper inductors and efficient boost converter IC
• Track widths must support required motor current safely
• Design must be suitable for long term operation
• Use low cost and easily available components
• Manufacturing cost target for PCB assembly should remain below Rs.100 if possible
• Avoid expensive or difficult to source components
• Design should be optimized for mass production
• Use proper grounding and power routing practices
• Thermal performance should be considered
• All SMD components should be placed on top side only
Deliverables Required
The freelancer must provide all production files required for manufacturing.
Required files:
• Complete schematic design
• PCB layout design
• Editable KiCad project files
• Gerber files
• Drill files
• BOM
• Pick and Place files
• 3D PCB files
• PDF schematics
• PCB fabrication outputs
• Assembly files
• Any additional files required for manufacturing
Workflow Requirement
Step 1:
Designer must first create and share schematic design for approval.
Step 2:
Only after schematic approval should PCB layout design begin.
Preferred Skills
Looking for a designer experienced in:
• DC-DC boost converter design
• Power electronics
• Battery powered PCB systems
• KiCad PCB design
• High current PCB routing
• Manufacturing ready PCB development
• Cost optimized electronics design
Additional Notes
This PCB must fit inside our existing RC product enclosure, so connector and capacitor placement
accuracy is very important.
The design should be clean, practical, and production ready, not just a prototype level design.
Please share previous similar power supply or boost converter PCB work while applying.
