About the AI-PCB

AI-PCB is an open source PCB design by ChengminLi, published on GitHub under the CC-BY-4.0 license. It is a 2-layer board measuring 100 × 76 mm, with 66 components from 49 distinct parts.

Other key parts include the UC3845BD1013TR, L78L12ACUTR, TL431AIDBZR and LTV-817S. By type, the board carries 23 capacitors, 19 resistors, 6 diodes, 5 connectors, 4 ICs and 2 inductors.

It belongs with the test & measurement designs in this gallery.

From the project

AI agent skill for designing and reviewing power-electronics PCBs, with a human review gate after every step

A small isolated flyback converter built as a live demonstrator for the EMC lectures at TU/e. Jumpers on the board, the "EMC knobs", switch the filter stages, the switching speed, a snubber, the potential of the heatsink case, the Y-capacitors, and the output earthing, so students can watch the conducted emissions change on two LISNs.

More: bottom copper, predicted board temperature.
