Custom 3S Li-Po PDB Design
Budget: ₹600 – ₹1,500 INR
I need a carefully-engineered power distribution board that can sit at the heart of a 3-cell Li-Po system, handle bursts up to 80 A (around 35 A continuous), and keep my analogue sensors reading cleanly even while five ESC-driven motors are spinning.
Core functions
• Step-down rails: two independent 5 V bucks and one 3.3 V buck to feed a Raspberry Pi, a Teensy, a standard servo and two analogue sensors.
• High-current bus: direct battery feeds for five ESCs plus an additional tap for a single analogue pressure sensor.
• Built-in protection: overcurrent, overvoltage and temperature monitoring are all mandatory, and the whole layout must be low-noise by design—analogue performance is the most critical element of the project.
What I expect to receive
1. Complete schematic (KiCad or Altium preferred, PDF export as well).
2. PCB layout ready for fabrication, including Gerbers, drill files and pick-and-place data.
3. BOM with manufacturer part numbers and at least one in-stock supplier link for every part.
4. Brief design note outlining key calculations, protection thresholds and any layout choices made to minimise noise on the sensor lines.
Please keep the board footprint compact, use connectors that can reliably carry the specified current, and allow reasonable heat dissipation without forced airflow. If you have questions about component choice or trace widths just let me know—I’ll respond quickly so we can keep momentum.
