Questions
How big is the TinyTimer V01 PCB?
It measures 88.9 × 57.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TinyTimer V01 use?
111 parts, built around the CH340C, ESP32-WROOM-32UE-N4, RX5808 and TLV75733PDBV. 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 TinyTimer V01 KiCad files?
From the cd334/TD_TinyTimer repository on GitHub, at the commit this page was made from: the board is HW/TinyTimer_V01/TinyTimer_V01.kicad_pcb and its schematic HW/TinyTimer_V01/TinyTimer_V01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TinyTimer V01 design in my own project?
Its repository states no licence, so its author keeps all rights: ask cd334 before reusing the design.
