Compact Line-Follower PCB Design
Budget: $10 – $30 USD
I’m building a line-following robot that must stay small yet reliably drive two 4 A motors and read a bank of analog QTR sensors. I need a concise, ready-to-route PCB package that covers:
• Schematic and single-board layout centered on an ESP32
• Twin H-bridge or driver stage capable of a continuous 4 A per channel
• Clean routing for 6–8 analog QTR reflectance sensors, keeping traces short for accuracy
• On-board 5 V and 3.3 V regulation with minimal noise
• Footprints and libraries compatible with Proteus so I can run quick simulations before fabrication
I’m prioritizing overall compactness, so component placement and board size matter more than extras. A basic Gerber set, BOM, and Proteus project file are all I need to move straight to prototype.
Looking for an expert PCB designer to create a custom board for a line-following robot chassis.
The design should handle 4A power, use 8 QTR-1A sensors, include programming ports and mode switches, and be compatible with both KiCad and Proteus.
Use common, low-cost components and deliver schematic, PCB layout, Gerber, and BOM files ready for manufacturing.
Key Requirements:
• 4A power circuit (robust and efficient)
• 8× QTR-1A line sensors
• Programming interface onboard (ISP/UART)
• Mode selection switches (DIP or toggle)
• Compact chassis-compatible layout
• Deliverables: KiCad + Proteus files, Gerber, BOM
