Switch
About the Switch PCB
Switch is an open source PCB design by Secoh, published on GitHub under the MIT license. It is a 2-layer board measuring 38.1 × 38.1 mm, with 17 components from 15 distinct parts.
By type, the board carries 6 resistors, 5 diodes, 3 connectors, 2 transformers and 1 capacitor.
From the project
Educational etudes related to electronics, schematics, PCB layout, etc.
Fairly random collection of designs related to my hobbies, with backup in hidden agenda. Historic items are in PCB123 (private vendor-specific, incompatible with anything else); more recent work is KiCad and LtSpice.
