Questions
How big is the Tbc PCB?
It measures 180 × 67 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tbc use?
130 parts, built around the STM32G051K8T6, CD74HC74M96, LM1086CS-3.3 and LM1086CS-5.0. 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 Tbc KiCad files?
From the philmcm/tbc repository on GitHub, at the commit this page was made from: the board is tbc.kicad_pcb and its schematic decoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tbc design in my own project?
Its repository states no licence, so its author keeps all rights: ask philmcm before reusing the design.
