ElectroLab AICheck

PCB checker

Run a board preflight before copper gets real.

Check schematic labels, footprints, polarity, routing, test pads, first power-up habits, and safety boundaries before ordering or soldering a board.

Safety first, always.

ElectroLab AI teaches theory, low-voltage electronics, and planning concepts. Mains voltage, switchboards, fixed wiring, high-current systems, and legal electrical work must only be performed by licensed electricians where required.

Open Safety Center

PCB preflight

Catch board mistakes before copper is ordered.

Choose a board type, mark checks as complete, and watch the risk map change.

Board risk map

LED timer board

Low current, but polarity and resistor values matter.

Readiness

0%

Sensitive areas

Timer pins, LED polarity, capacitor polarity.

Critical checks

3 high-risk checks still need attention.

This checker is for low-voltage learning boards. Mains, switchboards, fixed wiring, high-current systems, and legal electrical work must only be handled by licensed electricians where required.

Preflight checklist

Power nets namedPositive, ground, input, output, and signal nets are labelled clearly.Connector labels visibleEvery external wire has voltage, polarity, or signal direction marked.Pin 1 and orientation markedICs, modules, connectors, pots, and switches show orientation on the silkscreen.Polarity marks checkedLEDs, diodes, electrolytic capacitors, batteries, and supply inputs have clear marks.Decoupling close to ICsSmall capacitors sit near IC/module power pins, not at the far side of the board.High-current routes identifiedBattery, speaker, motor, buzzer, and output paths are routed wider and shorter.Ground return plannedNoisy load current is not forced through sensitive input or sensor ground paths.Clearance checkedBoard-house minimum trace/space rules and low-voltage spacing are respected.Test pads addedAdd pads for power input, ground, regulated rail, signal input, and output/load.First power-up plan writtenUse current limiting, measure rails first, and stop if current, heat, or smell is wrong.Licensed-work boundary clearNo mains, fixed wiring, switchboards, or legal electrical work is treated as a DIY board task.
