Questions
How big is the Master PCB?
It measures 115.2 × 100.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Master use?
22 parts, built around the B2B-XH-A(LF)(SN) and B4B-XH-A(LF)(SN). 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 Master KiCad files?
From the buntueng/TLB_gen2 repository on GitHub, at the commit this page was made from: the board is PCB/master/master.kicad_pcb and its schematic ALL_CODE_TLB_GEN2_FOR_EDITE/CODE_DEMO/PCB/master/master.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Master design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
