Questions
How big is the PCB v2 PCB?
It measures 147 × 17.3 mm and has 6 copper layers, 1.58 mm thick.
What parts does the PCB v2 use?
253 parts, built around the ESP32-S3-WROOM-1-N16, CAP1296-1-AIA-TR, TMP1075DSG and CYPD3177-24LQXQ. 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 PCB v2 KiCad files?
From the DodoZimmermann/lamp-2 repository on GitHub, at the commit this page was made from: the board is Hardware/Electrical/PCB_v2/PCB_v2.kicad_pcb and its schematic Hardware/Electrical/PCB/Microcontroller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB v2 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).
