Pi Zero Power PCB Finalization
Budget: $10 – $30 USD
I already have a two-board stacked layout for a Raspberry Pi Zero 2 W power-supply add-on drawn in KiCad 9. The footprints, outline, and general placement are finished; what is still missing are the actual copper connections between the designated power pins.
Here is what I need:
• Complete all required power nets, keeping the routing clean and within the physical constraints of the existing stackup.
• Run the full KiCad DRC to verify there are no clearance, net-tie, or unconnected-pin errors.
• Generate a production-ready Gerber set (Gerber X2 + drill files) plus the pick-and-place and BOM outputs most board houses expect.
• Provide the updated KiCad project so I can review the work.
Acceptance criterion: the milestone is released as soon as my chosen PCB factory uploads the files without returning any errors.
No assistance with the actual power-supply circuitry is required—only the routing and output files.
The small card is double sided, and the bigger card is single sided
Decoupling Capacitor Pack (single specification)
Install two capacitors in parallel between +5 V and GND, placed as close as possible to the Raspberry Pi header (within 10–20 mm), using short, wide traces.
Electrolytic capacitor: 1000 µF, ≥10 V, low-ESR, radial, polarized.
Connect positive to +5 V (GPIO header pin 2) and negative to GND (pin 14). Provides bulk energy to absorb load transients and prevents low-frequency voltage droop.
Ceramic capacitor: 0.1 µF (100 nF), X7R, ≥50 V.
Connect directly between +5 V and GND in parallel with the electrolytic. Shunts high-frequency noise and cleans fast edges.
Notes: Observe polarity on the electrolytic, keep leads short, and place the capacitors physically close to the power pins to maximize effectiveness.
