PCB trace lab
Route copper like it has to carry real current.
A visual PCB trace playground for current, width, length, copper weight, voltage drop, heat, and clearance intuition.
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 CenterCheck the whole board too.
Trace width is one part of board readiness. Use PCB Checker for polarity, footprints, test pads, first power-up, and safety boundaries.

Routing rule
High-current traces need width, short paths, good connectors, and sometimes copper pours or heavier copper.
Heat clue
If the trace has meaningful voltage drop, it is also dissipating heat. The board is part of the circuit.
Clearance warning
Clearance looks more comfortable for low-voltage learning boards, but still check manufacturer rules.
