Questions
How big is the BillCold V0.01 PCB?
It measures 53 × 53 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BillCold V0.01 use?
67 parts, built around the ESP32-S3, W25Q128JVSIQ, AMS1117 and USBLC6-2SC6. 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 BillCold V0.01 KiCad files?
From the willianlunca/termokip_hardware repository on GitHub, at the commit this page was made from: the board is projeto_eletronico/BillCold_V0.01.kicad_pcb and its schematic projeto_eletronico/BillCold_V0.01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BillCold V0.01 design in my own project?
Its repository states no licence, so its author keeps all rights: ask willianlunca before reusing the design.
