Overview

Switch is an open-source printed circuit board by BASM, from the BASM/sh repository on GitHub, published under the MIT licence. It is a 2-layer board of 45.5 × 45.1 mm with 32 parts on 30 nets, routed with 458 tracks and 30 vias.

It is built around the RS485, SP3481CN-L and LM78L05ACZ, with the ULN2803LV among its other parts. Its parts include 12 connectors, 10 resistors, 8 ICs and 2 diodes. It belongs with the AVR (ATmega, ATtiny) boards of this library.

Questions

How big is the Switch PCB?

It measures 45.5 × 45.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Switch use?

32 parts, built around the RS485, SP3481CN-L, LM78L05ACZ and ULN2803LV. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Switch KiCad files?

From the BASM/sh repository on GitHub, at the commit this page was made from: the board is circuts/switch/switch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Switch design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
